Today we have a chance to do some shooting with a ZB-26, a German-occupation 8mm light machine gun made at Brno in Czechoslovakia. The ZB-26 does not get nearly as much attention as LMGs made by the better known powers during the war, but it is an excellent weapon. In addition to being adopted by the Czech military, the gun was sold to about two dozen other countries and used in significant numbers by the Waffen SS.
As one would expect form its reputation, the ZB was smooth, reliable, and very controllable. For all the reasons discussed in yesterday’s history and disassembly video [here], it is a top notch firearm.
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 an aircraft observer’s weapon for attacking balloons — a role which required incendiary ammunition. With this in mind, Winchester’s Frank Burton adapted the .351 WSL cartridge from his 1905 and 1907 self-loading rifles into the .345 WSL, with a spitzer bullet. He designed an open-bolt, select-fire shoulder rifle to fire it, which became known as the Light Machine Rifle.
Burton’s rifle was to be usable both in an aircraft where it could be fixed to a Scarff mount for a wide field of fire or used by an individual on the ground, fired from the shoulder. It weighed in at just about 10 pounds (4.5kg) and had a pistol grip and straight-line design to bring the recoil impulse directly into the shooter’s shoulder and minimize rise during automatic fire. The barrel was finned for better cooling, and infantry barrels were equipped with bayonet lugs.
The most distinctive elements of the design, of course, are the dual top-mounted magazines. Each one holds 20 rounds, and each has a pair of locking catches. One position locks the magazine into a feeding position, and the other holds it up above the cycling of the bolt. The idea here was to keep a second loaded magazine easily accessible for an aerial observer, so they could reload without having to find another magazine somewhere in the aircraft. Contrary to some speculation, there is no automatic transition between magazines. When one is empty, the shooter must pull it back to the second locking position (or out of the gun entirely) and then push the second magazine down into feeding position.
Despite Burton’s work — which was well ahead of its time — the LMR had been rendered obsolete for its primary role by the time it was ready. Synchronized, forward-mounted Vickers machine guns firing 11mm incendiary ammunition were being mounted on aircraft, and were more effective on balloons and airplanes than Burton’s weapon would have been. Only this single example was ever made, and it was not presented for infantry consideration as far as I can tell. It was lost for many years before being discovered in a Winchester building, and eventually ending up in the Cody Firearms Museum with the rest of the Winchester factory collection.

The BESAL is a simplified redesign of the Bren light machine gun, developed by a BSA employee named Faulkner. The design of the gun was motivated by the disastrous retreat of the British Army from Dunkirk in 1940, where they abandoned a huge amount of weaponry and war material, including most of their Bren guns.
The Bren gun was in production only as the BSA factory, which was at great risk to German bombing — and the Bren included a number of complex parts that could not be effectively put into production elsewhere in the UK on short notice. It was with this in mind that Faulkner designed the BESAL, which used much simpler components which could be made in a great number of small shops. Decentralized production would have made it a much more resilient process in the case of invasion (similar to German small arms production late in the war).
By the time the BESAL prototypes were built, tested, and approved as being reliable and effective, however, the immediate threat of invasion had passed and the Bren was in production at the Inglis factory in Canada as well as at BSA. The BESAL design was shelved for use in case it became necessary again, but it never was.
The ZB-26 stands as one of the best magazine-fed light machine guns developed during the 1920s and 30s – it was a very popular gun for small military forces and many countries which did not directly buy it were strongly influenced by it. The Japanese Nambu Type 96 and 99 were heavily based on the ZB, and the British Bren was a direct evolution licensed from Brno.
The design dates back to 1921, when the Czech government began searching for a modern light machine gun. They tested pretty much all the guns available on the market at the time, and also solicited guns from Czechoslovak designers. Brothers Vaclav and Emmanuel Holek submitted their I-23 light machine gun, which would become the ZB-26 (LK vizor 26 in Czech terminology) and become the official Czechoslovak light machine gun as well as a popular commercial export for the ZB factory. More than 120,000 were made in several different calibers and sold to 24 countries between 1926 and 1939.
When the Germans occupied Czechoslovakia, they seized a huge number of these guns both from the military and guns still in the factory. This particular one was part of a Spanish purchase contract, but was completed under the oversight of Heinrich Krieghoff and supplied to German forces.
Mechanically, the ZB-26 uses a tilting bolt and a long stroke gas piston, in a combination that would be copied in many later designs. It is robust, accurate, controllable, and handy – a truly excellent all-around light machine gun.
When the United States entered World War One, its military has a relatively tiny handful of machine guns, and they were divided between four different types, as the military budget was small and machine guns were not given much priority. However, since the failure of his gas-operated 1895 machine gun design to become a popular military item, John Browning had been working on a recoil-operated machine gun to replace it. This work became serious in 1910, and by 1915 Browning had met with Colt and agreed to give them exclusive license to his new design — and they began to work with him to refine and perfect it.
When the United States realized that it would be fighting in Europe and would need machine guns in 1917, it held an open trial for designs which Colt and Browning entered. The Browning gun was the undisputed star of the show, firing 40,000 rounds with only one parts breakage and no malfunctions that were not the fault of ammunition or belts. The gun was almost immediately adopted and pushed into production. Ultimately, Colt would allow the manufacture of its guns by Remington and New England Westinghouse, and Browning himself would accept a lump-sum royalty payment from the government for its use, which was about 3.5 million dollars less than he was contractually entitled to — out of patriotism and a desire not to profit too much from the war.
Browning 1917 machine guns would see only brief combat use in World War One, first tasting action in September of 1918. They would remain a staple of US military armament through World War Two, however, improved after the Armistice to the M1917A1 pattern. The gun we are looking at today is an original WW1 M1917, mounted on an equally rare M1917 original tripod.
Out at the range today with the Chauchat, testing accuracy against a simulated MG08/15 nest at 150 yards. I’ll try out semiauto and full auto (in short bursts), and see how they compare. For reference, the US Army recommended never using the Chauchat beyond 400 yards, as it was not sufficiently accurate to be effective at greater distance.

The Belgian Army was the second to adopt the Chauchat automatic rifle, after the French. Almost all of Belgium was under German occupation during World War One, leaving Belgium significantly dependent on French aid for arms during the war. The initial Belgian purchases were standard 8mm Lebel CSRGs, but by 1917 Belgian engineers were working on a solution to convert the guns to the Belgian standard 7.65mm Mauser cartridge. This was completed by the end of the war, and the Chauchat remained a standard arm of the Belgian military after the war.
Work to improve the design continued, and an upgrades version was formally adopted in 1927. This included the 7.65mm conversion, with the best magazines made for any model of the Chauchat, as well as a series of dust covers to close off every hole in the gun (magazine well, ejection port, charging handle slot, and barrel shroud vents). The Belgians also replaced the original bipod with a much better type (similar to what they would use on the FN BAR), simplified the feed system, and added a tension latch to ensure reliable operation.
This new pattern of CSRG would be standard Belgian front-line armament until the FN BAR was adopted in 1930. The Chauchats were still in service with some units at the beginning of World War Two though, and saw service at that time.

John Browning developed the Browning Automatic Rifle for use by American troops in World War One, taking inspiration from the other light automatic weapons in service including the Chauchat, Lewis, and MG08/15. Rather than being used as a light machine gun as we would understand it today, the BAR was an “automatic rifle”, intended to be used in much the same way as the Germans would use the Sturmgewehr in WWII. It would be fired in semiautomatic mode from the shoulder or hip while advancing on the enemy, using steady fire to keep them pinned down. Once troops broke into close contact, the gun could be switched to fully automatic to provide overwhelming firepower for the final assault on a position. While the walking fire from the hip was not particularly realistic in practice, the fully automatic firepower was a huge boon to the infantry. While it filled the game role as the Chauchat, the BAR was a much more refined weapon and much easier to use effectively.
The BAR was showed to the US Ordnance Department in 1917, and the first order for them was placed with Colt in July of 1917. In short order further contracts would be placed with Winchester and Marlin-Rockwell, although it would take many months to fabricate the production tooling and perfect the design for mass production. A few hand-fitted guns were ready in February 1918 for a public demonstration, but significant quantities were not being built until July of 1918.
These guns would be shipped to France for use by the AEF, but not actually put into combat service until the Meuse-Argonne offensive in late September of 1918, due to General Pershing’s desire to keep them secret from the Germans until a large number could be used at once. As a result, the guns saw only very limited use before the war ended on November 11th. In total 102,173 BARs would be built, about half of them being finished into 1919, after the armistice. They would go on to be changed and updated for use in World War Two, but that is a discussion for another day. This particular gun is an excellent example of an M1918 BAR in correct World War One configuration, which is a rare find today.
The General Electric M134 “Minigun” is essentially an electrically-powered Gatling gun — the conceptual operation of the gun is identical to Dr. Gatling’s original creation. What has changed, however, is the chambering (it’s in 7.62 NATO), the power source (an electric motor), and the feed mechanism (belt-feed using M60 links instead of the Gatling’s Accles, Broadwell, or Bruce feeds). The weapon was a scaled down version of a 20mm rotary powered cannon devised for aircraft armament after WW2, hence the “mini” name. It was used primarily as helicopter armament, although it has found its way only ground vehicles as well. Firing between 3000 and 6000 rounds per minute, the Minigun is ideal for aerial engagements where the gunner only has a brief moment on target and needs to fire as much as possible during that moment.
It is a truly awe-inspiring weapon, and quite an experience to fire! In addition to destroying a truck with it, we will look at disassembly and functioning of the minigun — the delinking mechanism is really the most complex part of the weapon, and a very interesting device.
Thanks to Modern Arms of Tempe, AZ for providing the Minigun for this video! They offer the gun for rental, if you are interested in trying it out yourself.
Roller locking is a system that is not used in many guns and often confused with roller-delayed blowback — which is understandable, given the similarities between the systems. Roller locking was first developed as a modification of the German G43 rifle, and it is really a sub-type of flapper locking mechanism. It was most significantly used in the MG42, and also in the Czech vz.52 pistol. In essence, it uses rollers in place of flaps to lock the bolt and barrel securely together during firing, and depends on an external system (short recoil, in the case of the MG42 and vz.52) to unlock before it can cycle.

In addition to building three main patterns of straight-pull bolt action rifle for the Canadian military and the commercial market, Sir Charles Ross also experimented with self-loading rifles. Starting with a standard Ross Mk III, this experimental rifle has a gas piston and trigger to allow automatic fire and a very neat forced-air cooling system. A one-way ratchet mechanism (now broken, unfortunately) spins the fan when the bolt cycles, pushing air into a barrel shroud similar to that of a Lewis gun. This rifle was most likely made in 1915 or 1916 with an eye to a military light machine gun or automatic rifle contract — which never happened.
Thanks to the Canadian War Museum for providing me access to film this Ross for you!
Joseph Chambers invented a repeating flintlock weapon in the 1790s, and I think it is appropriate to consider it a “machine gun”. The design used a series of superposed charges in one or more barrels, with specially designed bullets that has hollow central tubes through them. This would allow the fire from a detonation charge to transit through a bullet at the rear and set off a subsequent charge. The result was a single trigger pull to use a flintlock action to start an unstoppable series of shots. Chambers made pistol and musket versions, as well as a full-on mounted machine gun.
He submitted his design to the fledgling US War Department in 1792, but it was not accepted. He brought the guns back to their attention when the War of 1812 was declared, and this time he found an eager client in the United States Navy. More than 50 of the machine guns were built and purchased to use on Navy warships. This version had 7 barrels, each loaded with 32 rounds, for a total of 224 shots, at (apparently) about a 120 round/minute rate of fire. The British found out about the guns and made some effort to reverse engineer them, and there was also interest in France, the Netherlands, and Spain. Ultimately, the potential unreliability of the system prevented more widespread adoption, but the gun is a fascinating example of early automatic firearms.

The perk for $100 Patrons is choosing a gun they would like me to find and film, and one such Patron (Mark) expressed a curiosity about US testing and lack of adoption of an MG-42 in .30-06 caliber. So, today we will discuss that (the trials gun was designated the T24) as well as why it took so long for the FN MAG to be developed and adopted.
In the world of converted semiautomatic “machine guns,” the Browning 1919 is a happy example of one of the most iconic and historically important US machine guns and also one of the cheapest semiautomatic belt fed guns available. This stems from two factors, primarily. One is that the Browning 1919, being developed from the water-cooled M1917 Browning, is a closed bolt system. Open bolt semiautomatic designs are not allowed by ATF, and so most semiauto machine gun conversions require substantial alteration to convert from open bolt to closed bolt — which the M1919 does not need. Second, the IDF used the Browning M1919 for many years and in large numbers, and surplussed many of them in the late 1990s. These guns came into the United States as parts kits in large numbers. This meant a glut of cheap guns, easily built as semi autos, and in an easily shootable caliber — 7.62mm NATO (as converted by Israel from their original .30-06 chambering).
Today, we are looking at an example of a semiautomatic converted M1919, and specifically at the various changes made by Israel to both improve the design and convert it successfully to the NATO cartridge.
The M1915 CSRG, commonly called the Chauchat after its primary designer, has a reputation as the worst gun ever put into military service. That reputation, however, is not deserved. It was not a great weapon, but it was a very serviceable gun for its day. The French needed a light automatic rifle *right now*, and needed it in large numbers. The Chauchat answered that call, and was used to great effect by many French soldiers.
The Chauchat’s poor reputation comes from a couple places, some justified and some not. First off, many US troops trained on M1918 Chauchats built in .30-06, which were poorly made and pretty darn bad guns. They were replaced by 8mm Lebel guns before going into combat, but the bad experiences of training stuck with many Americans. The biggest mechanical flaw in the Chauchat was its magazine. All automatic weapons are heavily dependent on good magazines, and the Chauchat used a magazine that was made of thin metal, easily damaged, and open on the sides for dirt and mud to enter. If the magazines were not treated well, the gun would become hopelessly useless.
In addition, many of the Chauchat guns in the United States today were deactivated at one time, and often badly reactivated. This has nothing to do with their original reliability, but it does a lot to perpetuate their reputation. This particular example is an original gun that does not appear to have ever been deactivated, and it ran flawlessly for me. It will be an excellent example for someone who can appreciate it!
