Forgotten Weapons
Published 15 Sept 2025The Sniper Rifle Experimental Model (S.R.E.M.) was designed by the “Czech Section” of small arms designers who had taken refuge in the UK to escape German occupation of Czechoslovakia. The intention was to develop a scoped sniper rifle that could be fired and cycled without disturbing the shooter’s sight picture. The idea that the designers came up with was to use the pistol grip as a moving charging handle, similar to the Czech BESA machine gun already in British service.
In 1944, the Essex Engineering Works in the UK got a contract to make 22 sample S.R.E.M.s, although only 2 were actually made. Really, the whole concept was a bit of a red herring, as the recoil from 8mm Mauser (this was made in 8mm, expected the post-war the UK would be adopting it or another modern rimless round to replace the .303) would disturb the sight picture regardless of the mechanism used to cycle the action. The project was cancelled in 1945, and this example is the only known survivor today.

French Trials FN CAL: Adding Rifle Grenade Capability
Forgotten Weapons
Published 10 Sept 2025In the 1970s when the French Army was looking for a new rifle 5.56mm, they tested a number of foreign rifles alongside development the FAMAS at St Etienne. These included the HK33, the M16, and the FN CAL — and today we are looking at the FN CAL. It already had a four-position selector switch (safe/semi/full/burst), fulfilling one of the French Army requirements. But it did not have sufficient grenade launching capability, and so several examples were modified for trials with unique rifle grenade launching hardware.
Ultimately the HK33 was the best performing rifle, but it was not seen as a politically acceptable option and the FAMAS was chosen instead. I have not seen the trials reports to understand specifically why the FN CAL was unsuccessful, but we know that it was unsuccessful in many other trials, and FN dropped it for the distinct FNC design instead before long.

Japanese Last-Ditch Pole Spear Bayonet
Forgotten Weapons
Published 8 Sept 2025Japanese bayonets followed the same trend of simplification as Arisaka rifles towards the end of World War Two, culminating in what is today called the “pole bayonet”. Abandoning even the fittings to mount to a rifle, these bayonets were intended to be lashed to a pole to create a spear. The Japanese government did not have the military forces to repulse an American invasion of the home islands, and was actively planning to sacrifice millions of Japanese civilians in a hopeless defense, literally having them charge American machine guns with spears. Some of this was done on outer island battles, like Saipan and Okinawa but the scale in Japan itself would have been unimaginable. It was the nuclear bombs on Hiroshima and Nagasaki that led to a Japanese surrender and prevented this from becoming a reality.

The Best Operational Briefcase: American 180 & Laser Sight
Forgotten Weapons
Published 5 Sept 2025The “American 180 Security Briefcase” is the best execution of the operational briefcase concept that I have yet seen. The idea is simple; hide a submachine gun inside an ordinary looking briefcase so that it can be carried in the open by VIP security without arousing attention. Sometimes this is done strictly for stowage (see the Uzi coming out of a Secret Service briefcase during the attempted Reagan assassination) and sometimes it is designed to fire from within the case (see the H&K MP5 operational case). This one is meant for firing.
Unlike virtually all other such cases, this one includes a sight, a helium-neon laser. That allows the gun to be actually aimed — what an idea! The firing mechanism is also well thought out, with a manual safety switch that powers the laser and firing solenoid, then a constant-pressure switch for the laser and a pressure pad for the gun. I don’t know who made this, but it was a commercially available product … and a very cool one at that!

Potato Digger at War: Marlin Model 1917 Machine Gun
Forgotten Weapons
Published 27 Aug 2025John Browning’s first machine gun design was a gas operated system that used a swinging lever instead of a linear piston. He presented the first prototype to Colt in 1890, and it went into production in 1895. The US Navy bought a couple hundred, but the Army opted not to adopt it (much to Colt’s surprise). It was offered for sale internationally, but didn’t become very popular until World War One broke out.
By this time, Colt had improved it a bit with a finned detachable barrel, and they started getting orders for thousands of the guns from Belgium, Russia, Canada, Britain, and elsewhere. Unable to keep up with demand, they licensed the design to the Marlin company. Marlin made a few additional improvements (pistol grip attachment, sights, and access door for clearing malfunctions) and made several thousand for allied nations as well as 2,500 fort he US Army to use as training guns in 1917. They further improved the design by changing it to a linear gas piston, and sold some 38,000 to the US military for aircraft use.

Soviet World War Two 50mm Light Mortars (RM-39 & RM-40)
Forgotten Weapons
Published 25 Aug 2025The Soviet Union decided to adopt a 50mm light mortar in 1937 as a company-level armament. The first such weapon they used was the RM-38, introduced in 1938. It was a complex design, with a gas venting system to adjust range (200m – 800m), a bipod specifically set to either 45 or 75 degrees, and a recoil buffering system. This was clearly too complex, and it was replaced by the RM-39 the next year. This remained a well-made mortar, but now had a freely adjustable bipod. However it quickly proved too complex and expensive and it was in turn replaced by the RM-40.
The RM-40 is a much more efficient (aka, cheap) design. It used simple stamped bipod legs and a heavy stamped baseplate. It still uses adjustable gas venting to set range and retains a simplified recoil buffer, but it is a much more quickly produced weapon. A 1941 model of completely different design did replace it though, and by 1943 the Soviet Union moved to 82mm mortars for better effectiveness.
The Soviet mortars were generally well liked by German troops who captured them, as they were significantly longer ranged than the German 50mm mortar. They were also captured in large numbers by the Finns, who used them as well but found them underpowered. In 1960 some 1,268 Soviet 50mm mortars of all models were sold by the Finnish Defense Forces to Interarms to be imported into the US. Some were registered and sold as Destructive Devices and some were deactivated and sold as dummies.

OSS Lockpick Pocketknife for Secret Intelligence Operatives
Forgotten Weapons
Published 23 Aug 2025In early 1944, the Office of Strategic Services purchase 1,000 specialized pocketknives made by Schrade. Instead of regular blades and tools, these were lock picking knives, with one small blade, three different picks, and two rakes. Able to easily pass as a normal pocketknife on casual inspection, nearly all of them were issued out to OSS Secret Intelligence agents across the European, Mediterranean, and Far Eastern theaters of operation. Today only a few are known to survive …

Pauly/Roux Pistols: The First Self-Contained Cartridges
Forgotten Weapons
Published 22 Aug 2025Samuel Pauly is the largely unrecognized father of the modern self-contained cartridge. In 1808 he patented a cartridge with a metal base that held a priming compound and attached to a paper or metal cartridge body holding powder and projectile. He followed this with an 1812 patent for a gun to fire the cartridges. What makes Pauly’s original system particularly interesting is that he did not use mechanical percussion (ie, hammer or striker) to ignite the primer compound, but rather a “fire pump”. A spring loaded plunger compressed air on top of the primer, heating it enough to detonate the compound in the same way that a diesel engine works. This was not a commercially successful system, though, and Pauly left Paris for London in 1814.
Pauly’s shop was taken over by Henri Roux, who continued making guns under the Pauly name while also improving the cartridges. These two pistols were made around 1820 and use a Roux cartridge with a mechanical striker hitting the primer compound in a Pauly-style cartridge case.

A Modern Integrally Suppressed Pistol for Everyone: The SilencerCo Maxim 9
Forgotten Weapons
Published 20 Aug 2025SilencerCo announced the Maxim-9 pistol in late 2015. Having gone through some huge growth of the past few years, the company wanted to expand its capabilities and thought that the time was right for a modern integrally suppressed pistol. It was a unique new design of modern semiautomatic pistol build from the ground up to be integrally suppressed. The action is a proprietary delayed blowback system with all of the moving parts in the back half of the slide. This leaves the front of the gun dedicated entirely to suppressor volume.
The guns were released at SHOT Show 2017, and were relatively slow sellers, because of the high price and the required NFA registration. The expected passage of the Hearing Protection Act around that time would have been a huge boon for sales, but did not ultimately happen. Still, production continued until tapering off in early 2021 as SilencerCo shifted priority to regular suppressor manufacture in the face of a boom in demand.
The project may not have been a massive success for SilencerCo, but it was still a worthy endeavor that they do not regret. It helped mature the company, forcing them to embrace new proficiency in things like GD&T and advanced quality control machinery. And the pistol is, in fact, very cool.

The Official American Boy Scout Rifle: Remington 4-S
Forgotten Weapons
Published 15 Aug 2025The scouting concept exploded into the American culture after 1907, with a multitude of local, regional, and national organizations setting up in the years before World War One. Among these was the American Boy Scouts, founded by William Randolph Hearst. In 1913 they adopted the Remington 4-S as their official rifle, a .22 Short caliber rolling block. It was initially sold directly and exclusively to Scouts for $5, although it was quickly added to the general Remington catalog.
This rifle was intended to be used for both target shooting and also military style drill. To that end, it had military-style furniture, a stacking swivel, and a bayonet lug with miniature bayonet. About 1500 of these were made in 1913, which was the only year of production. In 1914, probably having failed to make the hoped-for sales numbers, Remington renamed the gun the “Military Model” to expand its sale beyond just the American Boy Scouts.
Oh, and note that this was not the Boy Scouts of America! The ABS would have a series of legal fights with the BSA over naming rights, which the BSA finally won in the early 1920s. The ABS was never a very large organization, and it faded away entirely in the 1920s. The BSA opted not to have an official rifle, as it was shying away from firearms at the time after a couple well-publicized shooting accidents.

Interdynamic MP-9 SMG: Origin of the TEC-9
Forgotten Weapons
Published 13 Aug 2025The story of the Tec-9 begins with a Swedish company called Interdynamic AB and their designer Göran Lars Magnus Kjellgren designing a cheap and simple submachine gun for military use. It found no interested clients, and so the company decided to market it in the United States as a semiautomatic pistol. Kjellgren moved to the US in 1979, anglicized his name to George Kellgren, and founded Interdynamic USA with a partner, Carlos Garcia.
The pair produced a few dozen MP-9 submachine guns in 1982 (they were all transferrable, as this was before 1986) as well as a semiauto open bolt version called the KG-9 (Kellgren-Garcia). About 2500 of the KG-9s were made before later in 1982 the ATF determined that it was a machine gun, and they had to redesign it as a closed bolt semiauto, which they named the KG-99. At about this point Kellgren decided to move on to other plans, and he sold his interest in the company to Garcia, who formed a new company called Intratec. Kellgren used the proceeds to start Grendel a few years later.

Baker Pattern 1800 Rifle for Napoleonic Wars Sharpshooters
Forgotten Weapons
Published 11 Aug 2025The British military decided to organize their disparate small units of riflemen into a single standardized group in 1800. The 95th Regiment – the British Rifle Corps – was founded and it was equipped with a pattern of rifle designed by one Ezekiel Baker. This was a .625 caliber rifle with a 30” long barrel and a remarkably slow 1:120” rifling twist. That rifling was deliberately chosen to balance rifle accuracy with ease of loading and it worked quite well as a compromise solution. The Baker was considered effective on individual targets to 200 yards (300 with a particular skilled marksman) and area targets out to 500 yards.
The Baker was used throughout the Napoleonic Wars and only replaced in 1838 by the Brunswick rifle. This example is one of the original 1800 pattern, modified in 1815 to replace its distinctive bayonet bar (used to fit the large short sword bayonet made for the Baker) with a typical socket bayonet lug.

Colt SMG: First of the 9mm ARs
Forgotten Weapons
Published 8 Aug 2025With the expansion of SWAT teams throughout law enforcement in the 1980s, Colt realized that it was leaving a lot of sales on the table by not having a submachine gun it could offer alongside M16/CAR-15 rifles and carbines. They addressed this in the early 1980s by adapting a CAR-15 to 9x19mm. It used an adapter in the magazine well to fit modified Uzi pattern magazines (they were given hold-open tabs on the followers), and retained the same handling and controls as the full size AR. The SMG was made as a closed bolt, hammer fired, simple blowback action. By adding weight to the bolt carrier and buffer, the rate of fire was kept down to around 800 rpm.
The Colt SMG never really captured wide appeal. It was reasonably successful for Colt in large part because of their ability to market it alongside rifles, but it was dogged by reliability problems. A bunch of different models were made with different fire control options, including a couple civilian semiautomatic models and the distinctive DoE “briefcase gun” and the integrally suppressed DEA model, although neither of those saw very substantial sales. Still, it remains available to this day.

Pick One: G1 (FAL) vs G3 (H&K) w/ John Keene
Forgotten Weapons
Published 2 Aug 2025If you had to pick one, would you take a G1 (FAL) or a G3 (H&K)? Both are 7.62mm NATO rifles adopted by Germany. The G1 has more features and capabilities, like the carry handle, bipod, multiple muzzle devices, and adjustable gas system. The G3, on the other hand, is simpler, without things to change for better or worse. So which would you take?

Swedish Paratrooper Prototype: AK Fm/57
Forgotten Weapons
Published 30 Jul 2025As Sweden was looking to adopt a new self-loading infantry rifle in the 1950s, one of the contenders was a modernized version of the Ljungman. The Fm/57 is one of the last iterations of that project. It is chambered for 6.5x55mm but uses the short-stroke gas piston conversion that we previously saw on the 7.62mm NATO conversions of the Ljungman. It also uses a more refined lower receiver than its Fm/54 predecessor, with a nose-in-rock-back 20 round magazine and a folding stock. It was entered into formal trials against the GRAM-63 (another domestic Swedish design), the M14, G3, SIG 510, FAL, and AR10 … which it lost.
