Forgotten Weapons
Published 21 Mar 2018In 1952, Czechoslovakia adopted a whole new family of small arms, including the vz.52 pistol, vz.52 rifle, and vz.52 light machine gun. The rifle and LMG were both chambered in the Czech 7.62x45mm cartridge, and both would be adapted to the Soviet standard 7.62x39mm a few years later, in 1957. Very shortly thereafter, the Czechs would also introduce a heavier universal machine gun version in 7.62x54mmR under the designation UK vz.59 (universal machine gun model 59).
The UK 59 was basically a scaled up sibling of the vz.52 and vz.52/57 machine guns, although it fed from a belt only, where its smaller predecessors had allowed either belt or magazine feed. It used a pivoting locking block system much like the Walther P38 and Beretta pistols, in conjunction with a long stroke gas piston much like that of the vz.26 light machine gun.
The weapon did not see much interest outside of Czechoslovakia, although it does remain in service in that region in the modernized 7.62x51mm iteration.
Thanks to Marstar for letting me examine and shoot their UK vz.59!

Negev 7: Israeli Scales up to a 7.62 NATO Machine Gun
Forgotten Weapons
Published 31 Mar 2025The Israeli Negev machine gun had a rather long development cycle, beginning in 1985 but not seeing final completion and issue until 1997. Once on the market, it proved to be a pretty successful weapon, used by the Israeli military and also a number of export client around the world. In 2012, IMI released an improved newer version, the Negev 7. This was made exclusively as a 7.62mm NATO caliber gun, as opposed to the original Negev which was only made in 5.56mm NATO.

ZB37: Czechoslovakia’s Super-Heavy Machine Gun
Forgotten Weapons
Published 12 Mar 2025The ZB37 began in 1930 as a design by none other than classic Czech arms designer Vaclav Holek. The Czechoslovakian military was still using the Schwarzlose heavy MG, and wanted something to replace it. To fill all the roles intended, there would eventually be three different models of the ZB37 — one for infantry, one for fortresses, and one for vehicle mounting.
Note that the factory designation for this gun at Brno began as the ZB50, and iterated to the final version being the ZB50. However, it was identified by the military as the ZB37 (for 1937, the year of adoption).
After a series of redesigns, an early version of the gun is finally adopted in 1935 as the ZB35. A series of improvements leads to the final ZB37 model. About 500 of the early ZB35s were produced, and most of these were used to fill export sale contracts. By the time World War Two begins, the Czechoslovak military has about 5,000 of the guns in its possession.
Interestingly, the gun uses a hybrid recoil and gas operating system, with a tilting bolt. It has two rates of fire that can be chosen, and uses the rear spade grips as the charging handle. It is belt fed, using continuous 100- and 200-round metallic belts and chambered for the 8x57mm Mauser cartridge.
During the war, both German and British forces made substantial use of the ZB37. The Germans purchased ongoing production from Brno, and the British had actually purchased a production license before the war began. For the British, the gun was called the BESA and used in several armored vehicles (still in 8mm Mauser) — with about 57,000 being made during the war. A number of export sales were also made, including Romania, Persia, China, and several others. In 1946 another 3,000 were ordered and manufactured for fortress use in the Czech Republic, serving until the end of Communist control of the country.

Glock 18 & 18C Machine Pistols: How Do They Work?
Forgotten Weapons
Published 3 Mar 2025After the success of the Glock 17 in Austrian military trials, the company chose two specific markets to target for expansion. One was competition shooters, for whom the Glock 17L was released. The other was the international law enforcement and military market, for whom they decided to make a machine pistol — the Glock 18. The 18 was released in 1986, a model identical to the 17 except for the addition of a rotary selector switch on the slide.
In response to complaints about the controllability of the Glock 18, the 18C (Compensated) was released in 1996. This was a new model which added four barrel ports and a lightened slide to the 18. Neither has ever been really successful simply because machine pistols are by their very nature not very practical.
The question we are going to look at today is how the Glock 18 system works. As one would expect from Glock, it is a quite simply mechanical change to the semiauto lockwork.

WF-54: The Swiss FG-42 Scaled up to 7.5×55
Forgotten Weapons
Published 19 Aug 2024After World War Two the Swiss needed a new self-loading military rifle to replace their K-31 bolt actions. Two major design tracks followed; one being a roller-delayed system based on the G3 at SIG and the other being a derivative of the German FG-42 at Waffenfabrik Bern. Bern, under the direction of Adolph Furrer, had been experimenting with intermediate cartridges since the 1920s, and they used this as a basis to develop an improved FG-42 using an intermediate cartridge (7.5x38mm). The program began in 1951 and went through about a half dozen major iterations until it ultimately lost to the SIG program (which produced the Stgw-57).
Today we are looking at one of the later steps in the Bern program, the WF-54. By this point the intermediate cartridge had been discarded in favor of using the standard Swiss GP11 (7.5x55mm). The overall design was a bit simplified as well. The Bern program would continue for two more years after this rifle before ultimately losing out to the SIG 510 for Swiss military adoption.

Steyr-Solothurn S2-200: the Austrian MG30 and Hungarian 31M
Forgotten Weapons
Published 23 Sept 2024The S2-200 was developed by Louis Stange at the Rheinmetall company in Germany in the late 1920s. Because Germany was not allowed to be doing this sort of arms development at the time, Rheinmetall bought a controlling stake in the Swiss firm Solothurn AG, to make the product deniably Swiss. The gun itself is recoil operated, with a rotating locking collar connecting the bolt and barrel, rather like the Hotchkiss Portative. It was a design that had some early influence on the German MG34, although the German military declined to adopt it. Instead, it was taken into service in 8x56mm by both Austria (as the MG30) and Hungary (as the 31M). A third purchaser was El Salvador, which purchased 47 examples in 7x57mm caliber.
After the anschluss in 1938, the Austrian guns were integrated into the Wehrmacht, where they were primarily used by mountain troops. Hungary did later make a version in 7.92x57mm, designated the 43M.

Small Arms History of the Falkland Islands Defense Force
Forgotten Weapons
Published 12 Feb 2025Various militias existed on the Falkland Islands since its earliest settlement, but the Falkland Islands Defense Force of today traces its roots to the 1892 Falkland Islands Volunteer Corps. This force was equipped with Martini Henry rifles. With the outbreak of World War One, the Falklands were a strategically important naval station, and the FIDF grew significantly in size and was fitted out with more modern arms. They expanded again in World War Two, with Lee Enfield rifles, Sten MkV SMGs, and Bren, Lewis’s and Vickers machine guns. Eventually in 1972 the force modernized, acquiring British L1A1 SLR rifles, L2A3 Sterling SMGs, and GPMGs (FALs and FN MAGs) and updating its Bren guns to 7.62mm. These were the standard arms at hand during the Argentine invasion in 1982, although the FIDF was not really an active participant in the resistance to the invasion. In fact, the British Marine party on the island was in the middle of being replaced when the invasion happened and twice the normal number of Marines were present. They armed themselves with most of the FIDF SLRs, leaving the FIDF with mostly just SMLE rifles.
After the war, the FIDF was reconstituted. It kept its SLRs until the early 1990s when they were replaced with 5.56mm rifles. Instead of adopted the British L85A1, the FIDF opted to purchase Steyr AUGs. The intention was to replace the GPMG with the heavy-barreled AUG, but this did not work out in practice. Instead, the GPMGs remained in service and the heavy-barreled AUGs were converted to standard rifles. In the post-war years the FIDF also began to acquire more specialty arms, starting with a Parker-Hale M85, a couple of Steyr HS-50s, and ultimately a batch of LMT 7.62mm rifles. They remain a small but quite well-equipped for today, offering valuable reconnaissance and local knowledge to the British Army garrison should conflict break out again.
Many thanks to the FIDF for giving me access to their armory to dig out these arms to film for you!

Praga I-23: Prototype Belt-Fed Predecessor of the ZB26
Forgotten Weapons
Published 3 Feb 2025Vaclav Holek’s first machine gun design for the Czech military was the Praga I, built in 1922 and based heavily on the Vickers/Maxim system. However, it became clear that the military wanted something lighter and more portable, and so the next year he heavily updated the design to this, the Praga I-23 (for 1923). It remains a belt-fed weapon chambered for the 8mm Mauser cartridge, but the locking system has been much simplified into a tilting bolt arrangement. The recoil operation from the earlier model is also gone, now replaced by a long stroke gas piston. Some elements of the Maxim remain in the belt feeding elements, but the overall gun is much more a light machine gun than the mounted heavy machine gun that was his first design.
A total of 40 of the Praga I-23 were ordered by the Czechoslovak military, and they were tested in 1924 (only 20 examples were actually delivered of the 40). The I-23 performed well, but it was again clear that it wasn’t quite what the military really wanted. Holek revised the design again to the model 1924, using a box magazine instead of a belt feed — and that is the gun that continued the path to the ZB-26.

Praga I: A Blow-Forward Bullpup Semi-Auto-Selectable Vickers Gun
Forgotten Weapons
Published 15 Jan 2025The Praga I was the first machine gun design from noted Czech arms designed Vaclav Holek. Three examples were made for Czech military testing in 1922, but they were not acceptable. Instead, this design served as the first stepping stone to the eventual development of the ZB-26, perhaps the best of the interwar light machine guns.
Mechanically, the Praga I is largely based on the Vickers/Maxim system except with a locking wedge instead of a toggle joint. It also uses a forward-moving gas trap sort of action instead of recoil operation like the Maxim/Vickers. The fire control mechanism is essentially a Vickers lock, just built into the receiver of the gun instead of in a moving bolt or lock. It is a truly fascinating system!
Many thanks to the VHU — the Czech Military History Institute — for giving me access to this fantastic prototype to film for you.

Modernizing Le Clairon: the FAMAS Valorisé
Forgotten Weapons
Published 25 Dec 2024The FAMAS was the best bullpup rifle of its era, but it was a difficult platform to modernize with optics. In 1995, the “FELIN” (Fantassin à Équipement et Liaisons INtégrés; Integrated Infantry Equipment and Communications) was commissioned to create a next-generation weapons platform for the French soldier. This used a computerized multi-function optic mounted to a lowered rails system and a control keypad on a new front grip on the rifle. Like the American Objective Force Warrior and other similar programs, FELIN was not successful — but the base rifle did have a future. By dropping the new keypad-integrated lower assembly for the original FAMAS F1 lower but keeping the lowered upper assembly with its Picatinny rail, the FAMAS Valorisé was created, allowing much improved optics mounting.
These new rifles still used the FAMAS 25-round magazine, but now had Beretta-made barrels with 1:9 rifling, suitable for M855 and other heavy 5.56mm loadings. The Valorisé also included a small piece of rail specifically for an IR laser and added pivot to the bipod (which remained free-floated from the barrel). A total of 18,500 rifles were converted, and in 2015 they were used to equip 17 French regiments — and they saw some combat use in Afghanistan. Had the FAMAS platform been retained, this would have been the basis for its further modernization — but with adoption of the H&K 416F instead, the Valorisé rifles are being decommissioned.

The First Sturmgewehr: The MKb42(H)
Forgotten Weapons
Published 27 Nov 2024The first iteration of the iconic German Sturmgewehr was developed by Haenel starting in 1938. It was a select-fire rifle chambered for the short 8x33mm cartridge, developed by the Polte company. It used a long-stroke gas piston and a tilting bolt patterned after the Czech ZB-26 light machine gun. What makes the MKb42(H) stand out from the later Sturmgewehr models is that it was an open-bolt design. The original design spec was concerned about preventing cook-offs, and so it required firing from an open bolt. This means a very simple fire control system, but it also made the rifle difficult to shoot accurately in semiautomatic.
The first MKb42(H) prototype was finished in 1941, with 50 sample guns produced by late March 1942. A major trial was held in April 1942, in which Hitler rejected the design (mostly, he disliked the smaller cartridge). Development was continued anyway, with a move to a closed-bolt system that would become the MP43/1 which was ready for its first testing in November 1942. The open-bolt 42(H) was put into production anyway, as a stopgap measure to provide some much-needed individual firepower to troops on the Eastern front. Serial production began in January 1943, and continued until September 1943. In total, 11,813 of the rifles were manufactured. They saw use in Russia until replaced by newer MP43 models, and represent the first combat use of the assault rifle concept.

A century of war: The cartridge that remains deadly on today’s battleground
BFBS Forces News
Published 19 Oct 2024Say “7.62mm” when talking about rifle and machine gun rounds, and most people will think of the Nato cartridge that was introduced in 1954, but there’s a far older one that’s still in use – the 7.62x54mmR.
While the 7.62x51mm Nato cartridge was brought into service in 1954, the 7.62x54mmR dates back to 1891 in Imperial Russia.
Although this cartridge was developed in Russia, the “R” actually stands for “Rimmed” and this is what makes these two 7.62mm cartridges so different.
