Prototype & Trials Weapons
  • Frommer Prototype Semiauto Rifle

    Rudolf Frommer was a self-taught engineer and firearms designer who worked his way up through the FEG concern in Budapest to eventually hold the position of CEO. During this time he developed a series of long-recoil, rotating-bolt pistols culminating in the Frommer Stop, which was adopted by the ...

  • George Hyde's First Submachine Gun: The Hyde Model 33

    George Hyde was a gun designer who is due substantial credit, but whose name is rarely heard, because he did not end up with his name on an iconic firearm. Hyde was a German immigrant to the United States in 1927 who formed the Hyde Arms Company and started designing submachine guns. His first wa...

  • Spanish 8x33mm Mosqueton CB-51

    The Spanish military, like many others, was quite interested in developing a new semiautomatic or selective fire combat rifle after World War II. Franco's political ties to Germany (combined with Spanish neutrality in the war) gave them unusually good access to German arms designs, and the Spanis...

  • America's First Assault Rifle: Burton 1917 LMR

    America's first assault rifle? Well, it does meet all the requirements - select-fire, intermediate cartridge, and shoulder-fired. It was never actually fielded, though.

    The Burton Light Machine Rifle was developed during World War One, with the firing model completed in 1917. It was intended as ...

  • Bjorgum 1905 Norwegian Prototype Pistol

    Niels Bjorgum was a Norwegian artist-turned-gun-designer who decided to try his hand at handguns for the Norwegian military. His design work ran from 1894 until 1921 or so, starting with long guns but later turning to handguns. He was able to convince the Norwegian government to sponsor his work,...

  • WF Bern C42 & E22: Stgw90 Trials Rifles to Compete With SIG

    Today at the Kessler auction house in Kreuzlingen Switzerland we are taking a look at the W+F Bern C42 and E22 rifles. These are the guns supplied by Bern to compete for the Swiss military Sturmgewehr 90 trials. The C=type ones are chambered for the 5.56mm cartridge, but Swiss adoption of that ca...

  • Steyr M95 Straight-Pull Semiauto Conversion

    This rifle is a Steyr M95 straight-pull carbine that has been converted into a semiauto by adding a gas piston under the barrel connected to the bolt carrier, and an extension to the stock and receiver for the bolt to travel in. The pistol grip was added so that the trigger group could remain unc...

  • Before the Lewis Gun was the McClean Automatic Rifle

    Samuel McClean was a medical doctor from Iowa who began tinkering with firearms designs in 1889, and formed the McClean Arms Company in 1896. He was an intelligent and talented designer, but never quite managed to get a gun good enough for military acceptance. His work included bolt actions rifle...

  • Thompson SMG in 30 Carbine

    When the US military released a request for what would become the M1 Carbine in 1940, the Auto-Ordnance Corporation offered up a Thompson submachine gun simply rechambered for the new .30 Carbine cartridge. This entailed a new magazine, a receiver modified for the longer magazine, and a new barre...

  • Hudson Machine Gun

    Robert F Hudson developed a series of machine guns for the US Navy during the 1920s and 1930s, including this .30 caliber example as well as .50 caliber and 1.1 inch versions. What makes these guns unusual is both the attempted use of a counter-balanced system to eliminate felt recoil and also th...

  • Experimental Remington-Keene: Preventing Magazine Detonations

    This is a fascinating experimental Remington Keene rifle, build in an attempt to alleviate concerns about magazine tube detonation. With centerfire ammunition in a linear tube magazine, there was an ever-present (if very slim) risk of a bullet detonating the primer ahead that it was resting again...

  • Colt Sidehammer "Root" Dragoon Prototype

    During the development of the 1860 Army revolver, Colt did consider mechanical options other than simply scaling up the 1851 Navy pattern. One of these, as evidenced by this Colt prototype, was an enlarged version of the 1855 Pocket, aka Root, revolver. That 1855 design used a solid frame and had...

  • Italian Trials Czech ZK-391 Semiauto Rifle

    The ZK-391 is one in a series of Czech developmental semiautomatic rifles designed by Josef Koucký. It was developed initially in 1939 (hence the "39" in the designation), and was tested by the Italian military in 1943. It was ultimately not put into production, but nonetheless is an interesting ...

  • SA80 History: The First L85 Mockups (Sterling and Stoner)

    The British military had been working towards a reduced-power cartridge since the end of World War 2, and the ultimate adoption of the FAL/SLR in 7.62x51mm NATO did not end their interest in the concept. It would not be long before the roots of SA80 would take hold, and today we are looking at th...

  • SA80 History: XL60 Series in 4.85mm

    Once the basic configuration of the new British rifle was determined, the next step was to build a series of prototypes. The design that took form was basically a bullpup copy of the Armalite AR-18. The design team at Enfield were mostly senior draftsmen, with virtually no firearms experience amo...

  • SA80 History: XL70 Series Final Prototypes (Individual Weapon and LSW)

    By 1980, the scheduled deadline for adopting the L85 and L86 was rapidly approaching, and the weapons should have been in the last stages of fine-tuning before production began. This was not the case, however - testing was still uncovering critical problems in the guns.

    The goal for these weap...

  • SA80 History: The Pre-Production XL85 and XL86

    The SA80 saga continues today with the final pre-production versions of the L85A1 and L86A1, although at this point they still both carry XL designations, as they were not yet formally adopted weapons. In these weapons we can see a couple last distinctive mechanical changes, but perhaps more impo...

  • SA80 History: L22A2 and Experimental L85 Carbines

    One of the original design intentions of the SA80 project was to replace the infantry rifle and the submachine gun with a single weapon that could fulfill both roles - hence the choice of a bullpup configuration. This would, theoretically, allow rifle ballistics and also SMG handling and maneuver...

  • 1891 Salvator-Dormus: The First Automatic Pistol

    The Salvator-Dormus has the distinction of being the world’s first semiauto pistol, being patented in 1891. It is chambered for the 8mm Dormus cartridge, and holds 5 rounds in a Mannlicher type clip. Only about 50 of these pistol were made, mostly for an Austrian military trial in 1896/7 (this pa...

  • Savage .25 ACP Prototype Pocket Pistols

    Savage was very successful with their .32 ACP and .380 ACP pocket pistols, and in the 1910s was interested in also breaking into the .25 ACP market, to compete with the Colt 1908 "Baby Browning". Savage invested in all the tooling to make a new blowback .25, but never put them into serial product...

  • Schwarzlose 1901 Toggle-Delayed Prototype

    Andreas Schwarzlose was a German designer who created several very interesting and unusual handgun designs (in addition to his 1907 heavy machine gun, which was adopted as a standard arm of the Austro-Hungarian military). His first handgun was the model 1898, a short recoil, rotating bolt pistol ...

  • Sosso 1941 Italian Prototype Pistol

    The Model 1941 Sosso is a huge Italian experimental semiauto pistol designed by Giulio Sosso. It uses a short recoil locking mechanism and is chambered for standard 9x19mm Parabellum ammunition, but its more unusual feature is its magazine. Instead of using a traditional spring and follower, the ...

  • Prototype Friberg/Kjellman Flapper-Locking Semiauto Rifle

    The origins of flap-locking (as used in the G41(W), G43, DShK, DP, and RPD, among others) goes back to a Swedish Lieutenant Friberg in 1870, who patented the system. At that time, however, the fouling endemic to black powder made self-loading firearms effectively impossible and so the concept wou...

  • Unique Ross Experimental A2 Pistol Prototype

    This is a very rare Ross automatic pistol, patented in 1903 by Charles Ross, of the Ross Rifle Company in Quebec. It is a short recoil, toggle locked design, made for the .45 Ross proprietary cartridge (although efforts were made, unsuccessfully, to make a .45 ACP version for the US 1907 pistol t...
