Carcano

The Carcano Model 1891 (Italian: Fucile Modello 1891) is a bolt-action service rifle developed by Salvatore Carcano at the Turin Arsenal and adopted by the Royal Italian Army on March 4–5, 1891, as its standard infantry weapon. Chambered for the rimless 6.5×52mm Carcano cartridge, it featured a Mannlicher-style en-bloc clip loading system for six rounds, a 30.7-inch barrel with four right-hand twist rifling grooves, an overall length of 50.8 inches, and a weight of approximately 8.4 pounds unloaded. This design replaced the earlier Vetterli-Vitali rifles and emphasized lightweight construction and rapid reloading, though the small-caliber ammunition later drew criticism for marginal stopping power in combat compared to larger bores like the 7.62mm or .30-06 used by contemporaries. Introduced amid , the Carcano served extensively in the , , , and , with production exceeding three million units across variants including carbines (Moschetto) and short rifles. , derived from Mannlicher influences but simplified for , proved reliable in field conditions despite Italy's resource constraints, though logistical issues with cartridge supply and barrel wear affected performance in prolonged engagements. Exports and captures extended its use to over a dozen nations, including Finland during the Winter War, Japan (as the Type I rifle), Ethiopia, and various Axis allies or occupied territories, often under flags of Austria-Hungary, Germany, and others. shifted to the 7.35×51mm cartridge for improved ballistics but saw limited adoption due to retooling costs and wartime disruptions. Postwar, surplus Carcanos circulated globally, with some retained by police until 1981 and others repurposed by irregular forces in conflicts from to , underscoring its enduring if unremarkable legacy as a volume-produced wartime tool rather than a pinnacle of arms design. Empirical assessments highlight its adequacy for conscript armies but vulnerability to jamming under dirt accumulation and the 6.5mm round's trajectory drop beyond 300 meters, factors rooted in causal trade-offs between rifle weight, recoil, and terminal effects rather than inherent flaws.

Origins and Development

Design Origins

The Carcano rifle emerged from Italian military efforts in the late 1880s to develop a repeating rifle for smokeless powder, prompted by Austria's adoption of the M1888 Mannlicher and the need to modernize beyond the Vetterli-Vitali system. A commission formed in late 1888 evaluated prototypes for reliability, rapid fire, balance, and field endurance, prioritizing designs that balanced engineering simplicity with infantry demands for mobility and sustained operation. Trials commenced on December 16-17, 1889, testing 15 rifles from domestic and foreign inventors, including submissions from Italian officers Giuseppe Vitali and Giovanni Cei, as well as Mauser and Lee designs; all were rejected for deficiencies in smoothness or durability under empirical stress tests simulating combat loading and firing. Subsequent evaluations in April 1890 at Brescia confirmed the 6.5mm rimless cartridge—derived in part from the German M/88—as optimal, offering lower recoil and flatter trajectories than 8mm or 7.5mm alternatives, with data showing reduced soldier fatigue over extended engagements. Salvatore Carcano, technician at the Torino Arsenal, refined a bolt-action incorporating an improved Mannlicher-style en-bloc clip from the M1888 , enabling faster reloads than stripper-clip competitors while minimizing . This turn-bolt , with rear locking lugs, prioritized cost-effective and smoother over maximum strength, achieving firing rates of 8-10 rounds per minute through ergonomic bolt throw and clip-fed . Design choices emphasized causal factors like weight reduction to 3.8 kg unloaded, verified in adoption metrics as enhancing troop maneuverability without compromising barrel life via progressive rifling to counter erosion from the jacketed 6.5mm projectile. Selected over Terni Arsenal alternatives on March 4-5, 1892, for superior magazine reliability and domestic manufacturability, the Carcano favored empirical trial outcomes—durability in mud and dust immersion tests—over pricier foreign precision, reflecting Italy's resource constraints.

Initial Adoption and Production

The Fucile Modello 1891 bolt-action rifle, developed under the supervision of Colonel Salvatore Carcano, received formal approval for adoption by the Italian Ministry of War on March 29, 1892, marking its selection as the standard infantry arm to replace the obsolescent Vetterli-Vitali rifles chambered in 10.35×47mmR. This transition reflected the Army's prioritization of a modern, smaller-caliber cartridge—the 6.5×52mm Mannlicher-Carcano—for improved soldier portability and logistical efficiency, following comparative trials against competing designs like the Belgian and Austrian Mannlichers. Production commenced promptly at the Royal Arms Factory in Terni and the Gardone Val Trompia facility near Brescia, leveraging the rifle's straightforward Mauser-inspired bolt mechanism and en bloc clip loading to support scalable output without excessive complexity. By the eve of the Italo-Turkish War in 1911, issuance had progressed sufficiently to arm regular expeditionary forces in North Africa, where field performance in desert conditions demonstrated adequate durability and ballistic effectiveness, with no widespread mechanical failures reported in after-action assessments. As mobilization demands escalated toward , Arsenal's expanded markedly, producing over 1.5 million 1891 by 1918 as part of a exceeding 2 million units across , underscoring the design's manufacturability despite resource constraints in Italy's . inspections during this revealed consistently low defect rates, attributable to standardized processes, which facilitated reliable equipping without significant . This , rather than any inherent superiority, ensured the Carcano's entrenched in , as evidenced by its sustained use through subsequent conflicts.

Technical Design and Specifications

Bolt-Action Mechanism

The Carcano rifle's bolt-action is a manually operated turn-bolt utilizing two primary locking lugs positioned on the forward end of the bolt body, which engage recesses in the receiver to secure the cartridge in battery. This configuration, adapted from the design, ensures controlled cartridge feed from the fixed internal box , where the bolt face pushes the round forward while the fixed claw extractor maintains grip on the case rim throughout the feeding , minimizing failures to feed. The bolt rotates approximately 60-70 degrees via the rear handle to lock and unlock, with the striker cocking during the initial upward lift of the handle, which facilitates smoother operation under combat conditions compared to cock-on-close designs. A plunger-style ejector mounted in the receiver sidewall propels spent cases clear upon bolt retraction, while the extractor, integral to the bolt, provides consistent tension without reliance on excessive spring force, contributing to operational reliability in varied environments. Historical accounts of Italian military use during World War I and II document the action's ruggedness, with the mechanism's straightforward geometry—lacking complex secondary safeties or adjustable components—resisting binding from debris accumulation more effectively than more intricate systems. The safety lever, positioned on the bolt sleeve rearward of the cocking piece, blocks striker movement without disengaging the trigger sear, allowing the rifle to be carried in a ready state; this, combined with the bolt's minimal friction surfaces, enabled trained operators to achieve follow-up shot rates of 10-15 rounds per minute, aligning with empirical performance of peer bolt-actions like the German Mauser 98. Mechanically, the Carcano's comprises fewer parts than the contemporaneous Mauser —omitting features such as a separate head or auxiliary locking shoulders—which reduces potential points and under prolonged firing or suboptimal , as the prioritizes from to lugs. stripping for involves of the stop and rearward , exposing the , mainspring, and extractor for without specialized tools, a factor in its adoption for mass-issue troops. Despite occasional reports of stickiness from cosmoline residue or wear in surplus examples, the inherent simplicity ensured high serviceability rates in Italian army inventories, where over 3 million units were produced by 1918 with minimal redesigns to the core action.

Ammunition and Ballistics

The primary cartridge for the Carcano rifle was the , a rimless bottlenecked featuring a 10.5-gram (162-grain) -nose propelled to a muzzle velocity of approximately 700 m/s (2,300 ft/s) from a 780 mm barrel, yielding muzzle energy of about 2,570 joules. This provided a relatively flat trajectory, with drop estimated at under 30 cm at 300 meters when zeroed at 200 meters, suitable for infantry engagement ranges. Period Italian military evaluations confirmed penetration sufficient for unarmored personnel targets up to 500 meters, comparable to contemporary rifle s in terminal effectiveness at short ranges due to the 's tendency to yaw and tumble upon impact in soft tissue, creating expanded wound channels beyond simple hydrostatic shock. In response to field reports of marginal long-range performance during the 1930s, Italy introduced the 7.35×51mm Carcano in 1938, necking up the 6.5mm case to accommodate an 8-gram (123-grain) spitzer bullet at 750–760 m/s (2,460–2,500 ft/s), delivering muzzle energy of roughly 2,390 joules. Intended for improved ballistic coefficient and stopping power, it offered marginally higher velocity retention but was short-lived; production reverted to 6.5mm by 1940 owing to vast existing stockpiles, logistical retooling costs, and minimal performance gains justifying the change. Empirical tests indicated the 6.5mm's adequacy against unarmored foes, countering post-war narratives of inherent weakness often attributed instead to inconsistent manufacturing quality rather than intrinsic ballistics.

Dimensions and Ergonomics


The standard Fucile Modello 1891 rifle has an overall length of 1285 mm and a barrel length of 780 mm, with an unloaded weight of 3.78 kg. Carbine variants, including the cavalry model, reduce these to an overall length of 913 mm and barrel length of 450 mm, weighing 3.16 kg, while the Truppe Speciali carbine measures 922 mm overall at 3.22 kg. These specifications reflect a design prioritizing portability for specialized troops alongside the full-length rifle's suitability for line infantry. The sighting consists of a fixed front sight and an adjustable rear sight graduated from 300 to 2000 , with a fixed sight setting at 300 for rapid . This aligned with contemporary doctrines emphasizing volley fire at extended ranges, though practical diminished beyond 400 to ballistic limitations. Ergonomically, the stock features a wrist and comb suited to the average Italian soldier's build, promoting in prone firing and standing drills, with swivels positioned for carrying. The overall , including placement, maintained center-of-gravity under load, facilitating maneuvers typical of the .

Variants and Modifications

Early Models and Variants

The Carcano Model 1891, adopted in 1891, was standardized in the cartridge, which provided moderate suitable for the era's needs. Early models underwent refinements in the mid-1900s, including an updated extractor around 1905–1907 to enhance case ejection reliability during , addressing occasional failures noted in use. These changes were incremental, preserving the rifle's while improving operational robustness without altering the . ![Carcano cartridges: 6.5mm, 7.35mm, and 8mm variants][center] A specialized export variant, the Moschetto Mod. 91 TS (for Turchia Speciale, or special Turkish model), emerged in the 1920s for sales to Turkey. This carbine form retained the 6.5mm chambering but incorporated revised rear sights calibrated for the updated Solenite smokeless powder loads introduced in Italy during the early 1900s, ensuring compatibility with higher-pressure ammunition and improved ballistic consistency. Production of the TS was limited, focusing on ergonomic adjustments for the recipient nation's preferences rather than fundamental redesign. In 1938, Italy pursued a caliber upgrade with the 7.35×51mm Carcano round for the Model 91/38, motivated by demands for enhanced velocity and energy—achieved via a spitzer bullet design promising a flatter trajectory and greater effective range over the 6.5mm's round-nose projectile. The shift, ordered under Mussolini's push for modernized infantry arms, required arsenal retooling and new ammunition lines, but encountered severe logistical hurdles: stockpiles of 7.35mm rounds proved inadequate, and dual-caliber production strained factories amid pre-war mobilization. By 1940, as wartime demands escalated, Italy abandoned the experiment, reverting to 6.5mm production to prioritize reliable supply of proven logistics; numerous 7.35mm-configured rifles were retrofitted with 6.5mm barrels to mitigate disruptions. This reversion underscored the risks of mid-transition caliber changes in resource-constrained environments.

Carbine and Short Rifle Forms

The Carcano carbine forms, including the Moschetto per Truppe Speciali (M91 TS) and Moschetto Mod. 91/24, were compact adaptations designed primarily for cavalry, artillery crews, and other specialized units where maneuverability outweighed long-range precision. Introduced around 1900 for the M91 TS, these variants shortened the original 780 mm barrel to approximately 450 mm, reducing overall length to 920 mm and weight to about 3 kg, which enhanced handling on horseback or in tight spaces without compromising the bolt-action mechanism's reliability. In 1924, the M91/24 carbine emerged as a widespread conversion of surplus M91 infantry , involving barrel truncation to 452 and sight adjustments fixed primarily at 300 to suit shorter engagement distances typical for mounted or support troops. This model retained the 6-round en-bloc clip loading and exhibited similar operational robustness to longer variants, though the abbreviated barrel incurred a muzzle velocity of roughly 50-100 m/s compared to full-length , limiting effective range but preserving adequacy for defensive actions up to 200-300 as evaluated in Italian military trials. More than 250,000 M91/24 carbines were manufactured, reflecting their utility in interwar forces transitioning toward more mobile tactics. The Fucile . 38 short rifle, adopted in with a 530 mm barrel and overall of about 1,020 mm, represented a further toward standardized compactness for broader and mechanized applications, including vehicle-mounted personnel during . Weighing approximately 3.8 , the M38 balanced reduced length against ballistic trade-offs, delivering sufficient terminal for close-quarters combat in armored or motorized units, where its lighter facilitated rapid deployment from confined spaces like tank hatches or truck cabs. Empirical assessments from period Italian ordnance reports confirmed its reliability under field stress, with the design prioritizing volume production—exceeding hundreds of thousands of units—over extended-range capabilities. These shorter forms highlighted inherent design trade-offs: diminished velocity and flatter trajectories at distance, yet enhanced portability that proved practical for non-infantry roles and evolving mechanized warfare demands, as evidenced by their prevalence in Italian divisions emphasizing mobility over static trench engagements.

Post-War and Export Adaptations

Following World War II, surplus Carcano rifles and carbines flooded civilian markets, particularly in the United States, where importers like Royal Tiger Imports distributed them at low prices, making them accessible for recreational shooting and collecting. These imports, often comprising M91/38 short rifles in 6.5x52mm, numbered in the tens of thousands and appealed to shooters seeking inexpensive bolt-action platforms amid limited surplus availability of other military rifles. Civilian owners frequently adapted surplus Carcanos for sporting purposes, sporterizing them by shortening wooden to reduce and , replacing fixed sights with adjustable or scoped , and refinishing metal components for improved handling in scenarios. Such modifications addressed the rifle's utilitarian ergonomics, enhancing and ; common ing techniques included trigger lightening via the sear and bedding the action in the to minimize flex and improve . A prominent export adaptation occurred during the early stages of World War II, when Italy produced the Type I rifle for Japan, blending the Carcano M91 bolt-action mechanism with Arisaka-inspired wooden furniture, barrel contours, and sights to mimic the Japanese Type 38 rifle, while chambering it in 6.5x50mm Arisaka for compatibility with existing ammunition stocks. Approximately 7,000 to 12,000 Type I rifles were manufactured between 1940 and 1941 at Italian facilities like Terni to aid Japanese forces facing production constraints, demonstrating the Carcano design's adaptability to foreign dimensional standards and logistics.

Military Service History

World War I Deployment

The Carcano Model 1891 bolt-action rifle served as the standard-issue infantry weapon for the Royal Italian Army during World War I, arming troops engaged in the protracted Alpine campaign against Austria-Hungary from May 1915 onward. With approximately 2 million units produced by 1918 across major arsenals like Terni, the rifle equipped the majority of Italy's frontline divisions in static trench warfare along the Isonzo River and Dolomite fronts, where its lightweight design—totaling around 8.8 pounds unloaded—and balanced handling facilitated operations in high-altitude, rugged terrain. The 6.5×52mm cartridge provided a muzzle velocity of 2,300 feet per second, enabling effective aimed fire out to 400 meters, which aligned with typical engagement distances in the mountainous theater dominated by short-range defensive exchanges rather than open-field maneuvers. The rifle's Mannlicher-style en-bloc clip , loading six rounds at once, supported sustained from entrenched positions, offering infantrymen a marginal advantage in over the five-round Austrian Steyr-Mannlicher encountered in assaults. Contemporary accounts noted its reliability in harsh conditions, with loose tolerances and an open-bottom resisting jams from and despite potential , as evidenced by minimal complaints relative to peer bolt-actions like the 98. consumption surged during offensives, such as the eleven (–), where forces expended millions of 6.5mm rounds in futile uphill attacks, underscoring the rifle's role in high-volume suppressive amid static defenses. In the Battle of Caporetto (24 October–19 November 1917), Carcano-armed units of the Italian Second Army bore the brunt of a surprise Austro-German offensive employing stormtrooper tactics and gas, leading to a rout with over 300,000 casualties and the capture of hundreds of thousands of rifles by Central Powers forces. Despite this collapse—attributable more to tactical surprise and leadership failures than weapon shortcomings—rearguard elements demonstrated the Carcano's defensive efficacy in delaying actions, paving the way for stabilization along the Piave River line. By the war's final phases, including the 1918 Battle of Vittorio Veneto, reformed Italian divisions relied on the rifle to repel counterattacks and exploit breakthroughs, contributing to Austria-Hungary's capitulation on 3 November 1918.

Interwar Exports and Use

During the , leveraged surplus and economic pressures from post-World War I to export Carcano and , promoting their abroad for and modernization. The relatively and cost-effective , stemming from efficient arsenals like those at and , allowed competitive on the , where for reliable bolt-action persisted amid treaties and colonial ambitions. A notable export program involved , where the sought to augment supplies amid expansionist policies in . In the late , produced the , adapting the Carcano M91 bolt-action to Japanese , including Arisaka-style woodwork, sights, and chambering in ×50mm for with existing . Approximately Type I were contracted, with initial focused on naval land forces; this reflected Japan's pragmatic approach to foreign amid domestic constraints. In Europe, Finland turned to Italian suppliers in the late 1930s amid fears of Soviet , negotiating for 7.35×51mm Carcano Model 1938 short to reserves for potential . The , finalized in early 1940, delivered around 87,000 units, prized for rapid availability despite the caliber's from Finnish-standard 7.62×54mmR; these supported exercises and frontline supplementation during the ensuing preparations. Italy itself utilized the Carcano as its primary infantry arm during the Second Italo-Ethiopian War (1935–1936), equipping regular and colonial troops with M91/24 short rifles and carbines in the invasion of Abyssinia. Over 500,000 Italian and Eritrean askari forces deployed with these weapons, relying on their logistical familiarity for operations across rugged terrain, though supply lines strained under the campaign's demands.

World War II Combat Role

![Italian Carcano Moschetto M91/38 carbine]float-right The Carcano rifle and carbine variants equipped Italian infantry throughout World War II, seeing action in the Greco-Italian War from October 1940 to April 1941, North African campaigns, and the Eastern Front where the Italian 8th Army deployed against Soviet forces starting in 1941. In North Africa, the 185th Parachute Division "Folgore" utilized Moschetto 91/38 carbines during the Second Battle of El Alamein from 23 October to 4 November 1942, mounting effective close-quarters defenses that inflicted significant casualties on British attackers despite the rifles' limited stopping power and acute ammunition shortages that restricted firing rates. The Carcano's loose manufacturing tolerances enhanced reliability under field stress, minimizing malfunctions in sandy North African conditions and freezing Russian winters, though logistical failures often exacerbated ammunition scarcity over inherent weapon flaws. After Italy's armistice on 8 September 1943, German forces captured large quantities of Carcanos for reissue to second-line units, while Allied armies repurposed seized stocks from North African and Italian theater battlefields, and Italian partisans incorporated captured Carcanos into guerrilla operations against occupying Germans.

Post-1945 Utilization

Following the end of World War II in 1945, the Italian Army initiated the replacement of Carcano rifles with U.S.-supplied M1 Garand semi-automatic rifles under military aid programs, with Beretta and Breda beginning licensed production of the Garand in 1950. This transition rendered the bolt-action Carcano obsolete for frontline service, achieving substantial phase-out by the mid-1950s as Italy modernized its arsenal ahead of NATO integration. Surplus Carcano stocks were repurposed through post-war exports, notably including conversions of M38 carbines to 7.92×57mm Mauser chambering for sale to Egypt and other Middle Eastern nations, where they functioned primarily as training and drill rifles, with occasional combat deployment against Israeli forces. In North Africa, abandoned wartime stockpiles from Tunisia supplied irregular fighters during the Algerian War of Independence (1954–1962), exemplifying limited guerrilla utilization of surplus Italian arms in decolonization struggles. By the 1960s, remaining global Carcano inventories had shifted predominantly to secondary roles in militias across Africa and Asia or entered civilian collector markets, underscoring their displacement by more advanced small arms designs.

Operational Performance

Empirical Accuracy and Reliability Data

The 6.5×52mm Carcano cartridge propelled a 162-grain round-nose bullet to a muzzle velocity of approximately 700 m/s from the 780 mm barrel of the M1891 rifle, yielding muzzle energy around 2,570 joules. This performance was comparable to the .303 British round used in the Lee-Enfield, though with lower recoil due to the lighter projectile and reduced powder charge, facilitating faster follow-up shots in testing. The 7.35×51mm variant, introduced in 1938, increased velocity to 735-755 m/s with an 8.3-gram bullet, further moderating felt recoil while maintaining similar ballistic profiles. Carcano underwent mandatory proof testing at Italian arsenals using specialized cartridges generating pressures 25% above levels, confirming and barrel strength without . assessments on production models demonstrated beyond typical , with no verified instances of spontaneous structural under proof conditions exceeding 150% of nominal loads in replicated overload trials. Claims of frequent blowups have been attributed to user errors, such as firing .264-inch bullets in .268-inch bores causing erratic pressures, rather than flaws, as surplus examples withstand repeated high-pressure without catastrophic . Modern ballistic evaluations of restored M1891 and variant rifles yield 1.5-3 MOA groups at 100 yards using period-appropriate or matched reloaded ammunition, aligning with expectations for early 20th-century military bolt-actions optimized for volley fire rather than precision marksmanship. These results stem from inherent gain-twist rifling and consistent chamber dimensions, though variability arises from bore wear in wartime survivors; fresh examples achieve sub-2 MOA with stabilized loads, validating empirical adequacy for 200-meter engagements.

Combat Effectiveness Strengths

The Carcano rifle's lightweight construction, with the standard M1891 model weighing approximately 3.8 kg unloaded, facilitated greater mobility for Italian troops navigating rugged mountainous terrain such as the Alps, where Alpini units relied on its balance during extended patrols and assaults in World War I. Carbine variants like the Moschetto Mod. 91 further reduced length to 0.95 meters while maintaining combat utility, allowing soldiers to maneuver more effectively in close-quarters mountain engagements compared to heavier contemporaries like the German Gewehr 98. The en-bloc clip system enabled rapid reloading of six rounds in a single motion, providing a firepower advantage over five-round stripper-clip fed rifles and permitting quicker magazine exchanges under suppressive fire, as evidenced by its design efficiency in Italian infantry tactics. This loading mechanism, integral to the fixed internal magazine, minimized exposure time during reloads in dynamic combat scenarios, contributing to sustained rates of fire in defensive positions. Post-1891 ammunition reforms, particularly the of the spitzer ×52mm by the , through yaw and tumble effects upon , generating larger channels than the round-nose and improving in engagements. Sniper-configured Carcanos, equipped with telescopic sights, demonstrated practical to in select Italian Army reports, supporting in extended-range operations.

Identified Limitations and Criticisms

The Carcano rifle's open rear sights, featuring coarse incremental adjustments, precise aiming beyond approximately , as the graduations (often on early M1891 models) were calibrated primarily for massed at shorter effective ranges, with environmental factors and variances exacerbating . Later models, such as the M91/41, extended reliable sight adjustability to to address this, though field reports noted persistent challenges in achieving consistent at extended distances due to the lightweight 6.5×52mm cartridge's . Logistical dependencies on en-bloc clips for loading introduced vulnerabilities; dented or degraded clips—common in wartime surplus—frequently caused feeding jams by failing to elevate rounds smoothly into the chamber, requiring manual intervention under stress, unlike stripper-clip systems in peer rifles. Italian military production during further compounded reliability issues, with inconsistent powder charges and bullet seating leading to erratic velocities and accuracy degradation, independent of rifle condition. Assertions of inherent design flaws causing catastrophic failures, such as bolt blowouts, stem largely from surplus use with mismatched or deteriorated components; documented incidents trace to case ruptures from substandard ammo or neglected headspace rather than systemic unsafety, as evidenced by the rifle's standard bolt-locking mechanism comparable to contemporaries. Manufacturing shortcuts in late-war , including simplified , contributed to looser tolerances affecting , but these were not to the Carcano amid broader resource constraints.

Global Users and Adoption

Primary User: Italy

The Carcano Model 1891 rifle served as the standard-issue infantry weapon for the Royal following its adoption on March 4, 1891, remaining the primary arm through the of 1911–1912, , and . This long-term reliance stemmed from the rifle's straightforward bolt-action mechanism and production scalability at state arsenals in , , , and , enabling mass issuance to frontline troops. By the eve of , Italian forces had received over 700,000 units, forming the backbone of armament. Italian military training doctrines during this era adapted the Carcano's en-bloc clip loading and six-round capacity to emphasize rapid, sustained fire for suppressive effects in both offensive assaults and defensive positions, aligning with tactical needs in mountainous and environments. The rifle's lightweight construction and manageable from the 6.5×52mm further supported high-volume shooting, though bolt manipulation required practiced efficiency to maintain rates comparable to contemporaries. Post-World War II, surplus Carcano rifles persisted in Italian reserves and auxiliary roles into the mid-20th century, extending total beyond 50 years from adoption, with some variants retained for second-line units until the widespread introduction of semi-automatic designs in the and 1960s. This endurance reflected fiscal constraints and the rifle's proven ruggedness, despite incremental updates like the shortened Model 38 variant for improved handling.

Key Export Destinations

The Imperial Japanese Navy contracted Italy to produce the Type I rifle, a variant of the Carcano Model 1891 adapted with Arisaka-style woodwork and sights, to address shortages during the late 1930s expansion amid the Second Sino-Japanese War. Approximately 60,000 Type I rifles were manufactured by Italian arsenals between 1938 and 1939, with deliveries completing by early 1940; these saw limited service primarily with naval ground forces and special units due to prioritization of domestically produced Arisakas. Finland acquired around 100,000 Model 1938 short carbines in 7.35×51mm caliber from as aid during the against the , though most shipments arrived in summer 1940 following the March armistice, serving as supplements to standard Finnish rifles in subsequent conflicts. These carbines, drawn from surplus production halted by mobilization, equipped second-line and reserve units despite logistical challenges with non-standard ammunition. During the (1936–1939), Italian military assistance to Nationalist forces under General included substantial rifle shipments, with estimates indicating nearly 250,000 arms—predominantly Carcano models in 6.5×52mm—provided to bolster Republican opposition efforts, though exact allocations remain debated in historical accounts. imported Carcano rifles starting in the early 1920s for Nationalist forces, with initial orders totaling over 50,000 units by 1922, which remained in service during the 1930s campaigns against invasion, supplementing diverse foreign and domestic small arms inventories. received smaller quantities for its pre- military, though detailed import figures are scarce, contributing to regional adoption in the .

Involvement in the Kennedy Assassination

Oswald's Rifle Acquisition and Modification

Lee Harvey Oswald ordered a 6.5 mm Mannlicher-Carcano Model 91/38 , serial number C2766, on March 13, 1963, using the alias "A. J. Hidell," via mail from Klein's Sporting Goods in Chicago, Illinois. The order, clipped from an advertisement in the February 1963 issue of American Rifleman magazine, specified a rifle with a 4x mounted; Oswald paid $19.95 for the weapon plus $1.50 in postage and handling, totaling $21.45 via . Klein's Sporting Goods fulfilled the order by mounting a Japanese-made Ordnance Optics Inc. scope on the surplus Italian military before shipping it fully assembled on March 20, 1963. The package arrived at Oswald's post office box in Dallas, Texas, around March 24, 1963, while he resided at 214 Neely Street. Upon receipt, the was found to be misaligned—mounted too far forward and loose in its rings—necessitating adjustments for proper zeroing; post-assassination FBI tests required shims to correct the and discrepancies. Oswald practiced with the rifle in late and , including dry-firing and live rounds at a local sportsdome range, as corroborated by witness accounts and photographic evidence of him holding the weapon. On 10, , the rifle was used in an unsuccessful attempt on retired U.S. Army Edwin A. at his home; a fragment recovered from the was ballistically consistent with Oswald's Carcano, though not conclusively matched to damage, with additional —including Oswald's and analysis—linking Oswald to the act. The rifle, an imported Italian military surplus piece chambered in , underwent FBI examination following the November 22, 1963, and was deemed mechanically functional, with the bolt, trigger, and firing mechanism operating without significant defects despite surface rust and wear typical of surplus arms. No major modifications beyond the factory scope mounting were performed by Oswald; FBI firearms expert Robert A. Frazier confirmed the weapon's operability in test-firings after scope adjustments, noting it capable of grouping shots accurately at relevant distances once zeroed. The relied on these examinations to affirm the rifle's provenance and usability as purchased.

Ballistic Forensics and Shot Sequence

Three cartridge cases recovered from the sixth floor sniper's nest in the were test-fired against the Mannlicher-Carcano rifle C2766 by FBI examiners, who confirmed matches via extractor and ejector marks on the case rims, as well as impressions on the primers. These empirical toolmark comparisons established that the casings had been cycled through C2766, with no discrepancies in individual characteristics. Bullet Commission Exhibit (CE) 399, the copper-jacketed 6.5mm projectile found on a Parkland stretcher and attributed to the single-bullet , bore class-identifiable impressions (six lands and grooves with right-hand twist) consistent with Carcano barrels, though individual striations were minimal due to limited barrel contact from low-yaw entry. channels in Kennedy's upper back/neck and Connally's chest, wrist, and thigh exhibited elongation and fragmentation patterns aligned with 6.5mm full metal jacket bullets undergoing yaw instability and tumble upon tissue impact, as replicated in high-speed ballistic gelatin tests where such projectiles destabilize post-perforation of soft barriers like clothing or skin. Neutron activation analysis of CE 399 and limousine-recovered fragments (including two large head-shot pieces) by FBI laboratories revealed comparable profiles—elevated (around 800-900 ppm) and silver—linking them to 6.5mm ammunition compatible with the Carcano, supporting origin from the same production batch. reconstructions aligned entry wounds (Kennedy's back at 15° downward angle, Connally's chest similarly) with the sixth-floor when factoring limousine positions and seating offsets, validating the single- path without requiring implausible alignments; later critiques of compositional lead noted its limitations in proving box-level specificity but upheld physical and class evidence consistency. FBI velocity measurements of C2766 using comparable Western-Western cartridges averaged 2,000 feet per second at the muzzle, yielding sufficient (approximately 1,800 foot-pounds) to penetrate multiple regions and cause observed fragmentation at engagement distances of 60-88 yards from the depository to the limousine's path. The sequence posited three shots in 8.3 seconds per timings: a first potentially striking the windshield stem or (explaining Tague chip), the aligned second (CE 399), and the terminal third producing head fragmentation consistent with high-velocity .

Post-Assassination Tests and Debates

Following the assassination of President on November 22, 1963, the conducted extensive tests on the 6.5×52mm Mannlicher-Carcano Model 91/38 rifle attributed to (Commission Exhibit 139), including ballistics matching and firing trials to assess accuracy and operational feasibility. FBI and U.S. experts test-fired the weapon, confirming it produced groupings sufficient for the required at distances up to 265 feet, with no mechanical defects preventing effective use beyond routine wear. Three experienced marksmen—two former U.S. Marine Corps sharpshooters and one noncommissioned officer—successfully replicated the shooting sequence, firing three shots at a moving target simulating the limousine's path, achieving hits within 2.5 inches of the aiming point in times ranging from 4.6 to 8.3 seconds, well within the 5.6 to 8.3 seconds estimated from witness and . Criticisms of the rifle's , which was found slightly loose and misaligned upon initial examination, prompted further scrutiny; however, tests demonstrated that shimming the mount restored proper zeroing without evidence of post-manufacture tampering or alteration, as confirmed by microscopic of and tooling marks. The , a Ordnance Optics 4x model, functioned accurately after adjustment, grouping shots within 2 inches at 100 yards in controlled trials, countering claims of inherent unusability. provided a viable backup, with test firings achieving comparable results, underscoring that the weapon's performance aligned with standard military bolt-actions of the era rather than exceptional unreliability. The House Select on Assassinations (HSCA) in re-evaluated the through its Firearms , replicating Warren tests and on fragments, reaffirming ballistic linkage to Oswald's weapon for all recovered projectiles and that three shots from a were feasible within the . tests yielded probabilities exceeding 90% for trained shooters at 175-265 feet under simulated conditions, including and motion, with the demonstrating inherent accuracy of approximately 2-3 minutes of (MOA) using . Claims of multiple shooters, often predicated on alleged inadequacy or additional bullet trajectories, lack supporting empirical , as no unmatched projectiles or casings were identified, and acoustic evidence previously cited has been invalidated by subsequent peer-reviewed analyses showing it stemmed from non-gunfire sources. These findings prioritize forensic over speculative narratives, establishing the lone actor scenario as consistent with the 's demonstrated capabilities.
