Toggle actions are a relatively exotic locking system that are relatively common and well-known because the system was used in a pair of particularly successful early guns: the Luger and Maxim/Vickers. There have also been toggle-action shotguns, military rifles, sporting rifles, and submachine guns, but the system went out of favor by the 1930s (except in the mind of one Adolf Furrer).
Most toggle-action designs use the toggle as a locked breech system, unlocked by a secondary operating system (usually short recoil). However, toggle system can also be the basis for delayed blowback actions, as in the Pedersen rifle.

Infantry Weapons at Guadalcanal – WW2 Special
Update: The folks at the World War Two channel have taken down this video due to technical errors in the script. Here’s their explanation.
World War Two
21 hours ago
Video on Infantry Arms at Guadalcanal retracted. Indy explains why:Hi everyone. Indy here. As most of you know, I do the research and writing for all of the regular weekly episodes here. I host many of the specials as well, though I do not do the research for most of them- occasionally so, if it’s something that’s really in my field of expertise, like geopolitics, strategy, personal stories, communications, and international relations. The research for the other specials is done by a variety of specialists in their fields or historians, so we can maintain the quality you’ve come to expect from us. I understand, though, that many of you have serious issues with the research for the Guadalcanal infantry special. Our apologies for that- the research was done by an historian, a PhD [student], actually, and we also ensured it was double fact-checked, but obviously some serious mistakes slipped through. Live and learn. I will say that I think it is important that you continue to tell us when you take issue with something we present, since we strive to make the most complete and accurate documentary series possible, so although some of them are hard to read we appreciate such feedback from our community.
And this is from the researcher who worked on the script:

Hey guys! This is Marlon, the PhD student in question who helped with the researching and writing of the episode. Just to give a little background, I’m a volunteer researcher who helps with the channel over the summer while I’m not teaching/researching/taking coursework. I’m a military historian and my main academic focus is on social and cultural military history (i.e. what people’s wartime experiences were like and why. I’m especially interested in how people justify wartime violence and oftentimes the types of weapons they use play a role in that mental process, so that’s the context in which I usually think about weapons on the battlefield).I’m sorry that I let a lot of you down with the mistakes about the Garand and Arisaka, among others. To be honest, I was surprised to learn they were myths. But I certainly know now, and I don’t think I’ll be forgetting any time soon 😅 One thing that I firmly believe as a researcher and educator is that nobody has a monopoly on the truth, least of all me. I tell that to my students on the first day of class each semester. I certainly don’t presume that the degree I’m pursuing makes me infallible or instantly qualified for anything. And this was a classic example of just how wrong I can be sometimes!
For what it’s worth, I love war history just as much as anyone else in the community, and I’m sorry that my research wasn’t as rigorous as it might otherwise have been. I hope you all might be willing to give any future episodes of mine a second chance, and of course I’m all ears for any mistakes that you want to point out!

Australia’s FAL-Based L2A1 Heavy Automatic Rifle
Forgotten Weapons

Many the nations that adopted the FAL (or L1A1, in Commonwealth terminology) opted to also use a heavy-barreled variant of the same rifle as a light support weapon. In the Commonwealth, this was designated L2A1 and it was used by Canada, Australia, and New Zealand. The Australian model was build at Lithgow and supplied to the Australian and New Zealand forces, as well as being exported to a variety of other nations including Ghana, India, Singapore, Malaysia, Papua New Guinea, and others (total Lithgow production was 9,557). It has a 21″ heavy barrel and a distinct folding bipod with wooden panels that act as handguard when the bipod is folded up. Doctrinally, the L2A1 was intended to be used in semiauto most of the time, with the bipod and heavy barrel allowing greater sustained semiauto fire than a standard rifle.
A 30-round magazine was developed and issued, but abandoned before long. It was found to be insufficiently reliable, interfered with prone shooting, and contributed to overheating of the guns. Interestingly, Australia also opted to not have an automatic bolt hold open functionality in their FAL type rifles. The control can be used manually, but the rifle does not lock open when empty. This was presumably done in favor of keeping the action closed and clean at the expense of slower reloading (the same compromise was made on the G3 family of rifles).
This particular example is a registered transferrable machine gun made on a Lithgow receiver imported by Onyx in 1985 with other Lithgow-produced parts, including a 1960 bolt, 1961 carrier, and 1961 lower receiver from an L1A1 originally exported to Malaysia.

Rhodesian FAL – with Larry Vickers
Forgotten Weapons

The iconic weapon of the Rhodesian Bush War is the FN-FAL, painted in a distinctive “baby poop” yellow and green pattern. Because Rhodesia was under international embargo, its options for obtaining weapons were limited. Some domestic production was undertaken, but one large source was neighboring South Africa. Both South African production FALs and also Belgian-made South African contract FALs were provided. This rifle is one of the latter, with the South African crest and proof marks defaced for some theoretical deniability should it be scrutinized.
Larry Vickers will talk us through this FAL, pointing out the different elements that are distinctly Rhodesian, as well as the unique Halbeck Device — and detachable muzzle brake.
Thanks to Larry for sharing this rifle with us!

Shooting the Ishapore MkIII Vickers-Berthier LMG
Forgotten Weapons
Published 20 Sep 2017http://www.patreon.com/ForgottenWeapons
Cool Forgotten Weapons merch! http://shop.bbtv.com/collections/forg…
The Vickers-Berthier MkIII was adopted by the Indian army in 1933, and served through World War Two and into the 1970s (at least). It is chambered for the standard .303 British cartridge, fires from an open bolt, and uses top-mounted 30-round magazines. I didn’t know exactly what to expect when I had the chance to fire this one — and it turned out the be an excellent experience.
The rate of fire on the Vickers-Berthier is relatively low, and I found it to be an exceptionally stable and controllable gun to fire from its bipod. I don’t know if it’s the unusual muzzle brake design or other factors as well, but the sight picture remains stable and clear in a way that few other LMGs have matched in my experience.
Thanks to Marstar for letting me examine and shoot their Vickers-Berthier!

History and Disassembly of the Vickers-Berthier MkIII LMG
Forgotten Weapons
Published 19 Sep 2017http://www.patreon.com/ForgottenWeapons
Cool Forgotten Weapons merch! http://shop.bbtv.com/collections/forg…
The Vickers-Berthier was initially designed by Andre Berthier in France prior to World War One. It went through a number of substantial design changes before the war, and was actually ordered in quantity by the United States right at the end of WWI — but the order was cancelled with the armistice. In the 1920s, Berthier sold the design to the Vickers company in England, which wanted a light machine gun to market alongside its Vickers heavy machine gun.
When the British military decided to replace its Lewis and Hotchkiss light machine guns, the Vickers-Berthier was one of the leading contenders, although in the endurance trials it was edged out by the Czech ZB-33, which would ultimately be adopted as the Bren. However, the Indian Army opted to take the Vickers-Berthier, and it was put into production at the Ishapore Rifle Factory and saw substantial use in World War Two.
Mechanically, the Vickers-Berthier is a tilting bolt design with a long stroke gas piston. It has a thorough set of covers over the magazine well and ejection port, and a relatively slow rate of fire. The barrel is quick-changeable, and it feeds from top-mounted 30-round magazines, with an aperture type rear sight being offset to the left side of the gun to clear the magazine.

The M2 Browning machine gun was first conceived in 1918, as a request by General John Pershing of the AEF for a large-caliber anti-aircraft and antitank machine gun. John Browning scaled his M1917 water-cooled .30 caliber design up to .50 caliber, and the first prototypes were test fired in November of 1918. Impetus behind the project faltered after the Armistice, but Colt continued to develop the gun during the 1920s and 1930s. It was first adopted in 1922 by the US Coastal Artillery as an anti-aircraft gun, but significant manufacture would not come until World War Two. By this time, the gun’s main role had shifted, from antitank to being an aircraft armament, and some 2 million were made during World War Two, primarily as aircraft guns.
The M2 remains in service today, highlighting the brilliance and longevity of John Browning’s designs.

Colt R75A: The Last Commercial BAR (With Shooting)
Forgotten Weapons
Published 2 Mar 2018The R75A was the last version of Colt’s commercial BAR, with 832 made between August and December of 1942 for the Netherlands Purchasing Commission. It was a derivative of the commercial R75 BAR, with a pistol grip, magazine well cover, and ejection port cover. The R75A added on a folding bipod and a detachable barrel functionality, albeit not of the most elegant sort. To remove the barrel, one first used the lever under the muzzle to detach the gas block from the barrel by sliding it rearwards. Then a tool or cartridge tip was used to pry open the barrel locking lever at the front of the receiver, which then allowed the barrel to be rotated about 60 degrees to unlock its interrupted threads and remove it.

When the British military transitioned from the .303 British cartridge to 7.62mm NATO in the 1950s, it replaced the Enfield rifles with the new L1A1 SLR (the FAL) but retained the Bren gun as a support weapon. The Bren was updated to use 7.62mm, in a process more complicated than most people would think. Ultimately, only a few thousand L4 series Brens were made, as they were rather quickly supplanted by the FN MAG as a belt-fed support weapon.
The four different patterns of L4 are:
L4A1 – the initial pattern, without magazine supports
L4A2 – the Bren MkIII in 7.62mm with magazine supports
L4A3 – the Bren MkII in 7.62mm with magazine supports
L4A4 – the A2 and A3 patterns with chrome-lined barrelsContact:

MG-34: The Universal Machine Gun Concept
Forgotten Weapons
Published 7 Oct 2017The MG34 was the first German implementation of the universal machine gun concept — and really the first such fielded by any army. The idea was to have a single weapon which could be used as a light machine gun, heavy machine gun, vehicle gun, fortification gun, and antiaircraft gun. The MG34 was designed to be light enough for use as an LMG, to have a high enough rate of fire to serve as an antiaircraft gun, to be compact and flexible enough for use in vehicles and fortifications, and to be mounted on a complex and advanced tripod for use as a heavy machine gun.
Mechanically, the MG34 is a recoil operated gun using a rotating bolt for locking. It is chambered for 8mm Mauser, and feeds from 50-round belt segments with a clever and unique quick-change barrel mechanism. The early versions were fitted with adjustable rate reducers in the grips allowing firing from 400 to 900 rounds per minute, and also had an option for a top cover which would fit a 75-round double drum magazine. Both of these features were rather quickly discarded, however, in the interest of more efficient production. However, the gun fulfilled its universal role remarkably well.
The MG34 was considered a state secret when first developed, and despite entering production in 1936 it would not be formally adopted until 1939 — by which time 50,000 or so had already been manufactured. It would comprise about 47% of the machine guns in German service when the Wehrmacht invaded Poland, but would be fully standardized by March of 1941. It was replaced by the MG42 later in the war, as that weapon was both faster and cheaper to produce and also required substantially less of the high-grade steel alloys that Germany had limited supplies of. However, it would continue to be produced through the war, particularly for vehicle mounts.

Wartime Changes: The Bren MkI Modified and Bren MkII
Forgotten Weapons
Published 3 Mar 2021http://www.patreon.com/ForgottenWeapons

The British lost some 90% of their stock of Bren light machine guns in the disastrous Dunkirk evacuation, and in the following months rushed to rearm. Part of this program was a two-tiered simplification of the Bren design. First was a MkI Modified Bren (which was not marked any differently than the original MkI), and this was followed by a MkII design. These patterns simplified many of the machining operation required to produce the Bren, significantly reducing the number of required machining operations. The most visually distinctive elements of the MkII pattern were the omission of the stainless steel flash hider assembly and the replacement of the original dial rear sight with a simple ladder sight. In addition, changes were made to the buttstock, buttplate, receiver profile, gas block, and bipod. Both Enfield and Inglis would produce the simpler MkII Brens by the middle of the war. Despite the many changes made, the core operating components (bolt, bolt carrier, etc) were left unchanged, so they could still interchange between all patterns of the gun in service.

Very Rare and Mostly Pointless: the Bren Fixed Line Sight
Forgotten Weapons

https://www.floatplane.com/channel/Fo…
Cool Forgotten Weapons merch! http://shop.bbtv.com/collections/forg…
The very early production MkI Bren light machine guns were made with two dovetail brackets on the left side of the receiver. The rear one was for the standard rear sight, and the front one was to accommodate two types of optical sights. A mounting for the No.32 telescopic sight (the same one used on the No4(T) sniper rifle) was planned, but never produced. What was made in small numbers by the Plessey company was a “fixed line sight”. This was really more like a surveyor’s tool than a traditional sight, and it used the same optical element as the Vickers dial sight that was introduced alongside it in 1939. The purpose was to allow a tripod-mounted Bren to be set up with specific limits to its field of fire, and then for the gun to be removed, used on the bipod elsewhere, and returned to the tripod and confirm the field of fire, especially in the dark. This is a somewhat technically complex task, but not one that was actually needed very much for the Bren. As a result, production and use of the fixed line sights was very limited, and the sights are extremely rare today. The mounting bracket on the Bren receiver was rather quickly dropped from production as an unnecessary waste of machining time.

Bren MkI: The Best Light Machine Gun of World War Two
Forgotten Weapons

https://www.floatplane.com/channel/Fo…
Cool Forgotten Weapons merch! http://shop.bbtv.com/collections/forg…
In the years after World War One, the British military wanted a new machine gun, and they wanted it to replace both the Lewis and the Vickers. Through the 1920s the British would tinker with most of the light machine guns that became available, but it was not until the early 1930s that a serious formal trial was conducted. The initial trials found three particularly encouraging guns; the ZB-26, Madsen, and Vickers-Berthier. Over a series of followup testing, the Madsen and Vickers-Berthier were both eliminated, leaving the Czechoslovakian ZB as the final choice.
The British were extremely enthusiastic about the qualities of the ZB, and it is understandable why. The final .303 British version, the Bren, is widely regarded as the best magazine-fed light machine gun ever made. In its final preproduction trial, one of the prototype guns endured a 150,000-round trial without any real problems.
The design was licensed for British production as well as in the Dominions, and would be put into production at both Enfield in England and the John Inglis company in Canada. About 30,000 were produced before the Dunkirk disaster, which would lead to simplification of the design. But those changes are a subject for another video later…
