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 barrels

MG-34: The Universal Machine Gun Concept

Filed under: Germany, History, Military, Weapons, WW2 — Tags: , , , , , — Nicholas @ 02:00

Forgotten Weapons
Published 7 Oct 2017

The 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.

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

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.

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…

How Does it Work: Short Recoil Operation

Correction: Browning invented the pistol slide, but not the overall short recoil system. Maxim was the first to successfully create a short recoil firearm.

Short recoil is the most common system used today in self-loading handguns, and it also used to be fairly popular in machine gun designs. The basic principle is that the bolt and barrel (in a handgun, slide and barrel) are locked together for an initial travel substantially less than the overall length of the cartridge. After typically a few millimeters of travel, the barrel stops and the bolt or slide is able to continue rearward to extract and eject the empty case. Short recoil can be paired with virtually any locking system, but today the Browning tilting barrel system is most common.

Short recoil has never been popular in shoulder rifle, as the reduction in mechanical accuracy from the moving barrel can be undesirable. In handguns and machine guns, this accuracy reduction is generally below the threshold of relevance.

Italy’s WW1 Heavy Machine Gun: FIAT-Revelli Modello 1914

Italy was the first major adopter of the Maxim heavy machine gun and had several hundred by 1914 — but wanted to have a domestic design in production as well. The Italian government and military put a lot of resources into the Perino machine gun, but kept it so secret that it was never properly tested and development was very slow. By the time war broke out, the Perino was clearly not ready for field use — and Maxims (along with other foreign designs) were no longer available for commercial sale as production was being taken up by warring nations. This led Italy to adopt a private design of Bethel Revelli in partnership with the FIAT company.

Adopted as the Modello 1914, Revelli’s machine gun was a delayed blowback system with a wedge under mechanical disadvantage holding the bolt closed long enough to safely cycle. Its most unique element was the 50-round mousetrap-type box magazine that used 10 independent stacks of 5 rounds each (a 100-round version was also made). This was a very complex magazine to produce, and much more delicate than the other machine gun feed systems in use at the time. The Revelli is also notable for being the only major machine gun of the period to have a circulating water jacket, operated by a small hand-cranked pump on the condensing tank.

The FIAT-Revelli would see service as both and aircraft and ground gun through World War 1, and was updated in 1935 to an air cooled pattern that would serve through World War 2. These guns are very scarce in the United States today, and I am grateful to the collector who owns this one for providing access to it!

The MG42 was developed to be a more reliable and easier to manufacture replacement for the MG34, although both would serve side by side until the end of World War Two. Designed by Grossfuss company engineer Werner Gruner with no previous military or small arms design experience, the MG42 used heavy stampings for its main assemblies, thus reducing German need for expensive and difficult to obtain alloyed steels.

As a practical matter, the MG42 had a much higher rate of fire than the MG34, at 1500-1600 rounds per minute (more than 50% faster than the MG34). This was deemed desirable to improve the effectiveness of suppressing fire and the density of the cone of fire, but naturally resulted in much higher ammunition consumption than other machine gun models.

This example is a very early production Gustloff example, with the early horizontal charging handle, unreinforced wooden stock, and adjustable front sight. It was most likely captured in North Africa from Rommel’s forces, as they were a primarily user of the very early MG42s.

In November of 1950, the US Ordnance Department requested an improved version of the Browning 1919 air-cooled machine gun for use in tanks. The new version was to be able to feed from either the left or right, a feature which was unimportant for an infantry gun but much more relevant when mounting guns into the tight spaces of an armored vehicle. An interim conversion of existing guns to the M1919A4E1 pattern came first, followed by manufacture of all-new guns by the Rock Island Arsenal and Saco-Lowell company from 1955 until 1957.

The design of the gun fell to Bob Hillberg at High Standard. He came up with a clever set of reversible plugs to change the bolt between left and right hand feed, as well as a captive recoil spring, manual safety, improved top cover and rear cover latches, and several other strengthened parts. He also incorporated a charging handle extension with integral manual hold open and a link ejection chute that could be mounted to either side of the gun. His T153 design was formally adopted as the M37, in caliber .30-06. A 7.62mm NATO version (the M37E1) followed as well. The M37 would serve into the late 1960s on the M48 and M60 tanks as well as several helicopters.

Semiauto DPM Light Machine Gun Review

Filed under: History, Military, Russia, Weapons, WW2 — Tags: , , , — Nicholas @ 02:00

Forgotten Weapons
Published 7 Mar 2017

I have had a parts kit for a Soviet DPM light machine gun (actually a Polish one, but the design is identical) stashed away for many years now, with the hope to eventually have it built into a live gun. When I found out that SMG (makers of the sweet semiauto FG42 replicas) was making a new production run of DP and DPM barrels, receivers, and semiauto trigger conversions I jumped at my chance. I sent my kit to SMG, and they built it into this complete semiauto rifle.

The DP was introduced in 1928 as the standard Soviet light machine gun, and served through World War Two. In 1944, several defects were acknowledged and improved, notably the location of the recoil spring, the grip, and the bipod. This created the DPM, which did see some slight use at the very end of WW2, as well as use by several eastern bloc nations after the war (including in Korea). It would be updated again in 1946 with the RP46 conversion assembly to feed from Maxim belts instead of the distinctive pan magazines (and in fact, SMG is working on a reproduction of the RP46 conversion as well, although it is not yet ready).

Anyway, I took my new semiauto DPM out to the range and got a firsthand understanding of why these guns were so well liked by troops who used them. The design is nothing if not solid, rugged, and dependable. Like other iconic Soviet firearms, the DP/DPM is elegantly simple and bombproof. It is easy and comfortable to shoot, and SMG’s new and very clever linear hammer-fired semiauto conversion gives it a better trigger than any other semiauto machine gun conversion I have handled. Most such guns have really heavy and really creepy triggers, but this is about 8lb and very crisp – and that makes a huge difference in its shootability.

In a nutshell, the gun zeroed easily and shot well, it had no malfuctions in my 3 or 4 pans of ammo expended (using Czech surplus steel-case ammo), and was really a joy to shoot. I would not hesitate to recommend them, and SMG is offered everything from individual parts for you to build yourself to kit build services, and turnkey complete guns.

Light Machine Guns in Finland: DP-28 vs LS-26

Forgotten Weapons
Published 20 Jul 2017

http://www.patreon.com/ForgottenWeapons

Before the Winter War, the standard light machine gun adopted by the Finnish military was the Lahti-Saloranta LS-26. This was a complex and finely built weapon, using a short recoil action and tilting bolt, chambered for the same 7.62x54mm rimmed cartridge as used by Finland’s Mosin-Nagant infantry rifles. The LS-26 fed from 20-round box magazines which are a bit unusual in having a single-feed presentation (which made them difficult to load without a tool, but also prevented potential problems from rimlock).

In total, about 5,000 LS26 machine guns were made for Finland (and an additional 1,200 sold to China in 8mm Mauser). They were apparently quite accurate, but highly prone to malfunctioning in the cold and dirty field conditions of Finnish combat. When the Winter War broke out and Finns began capturing Russian equipment, the Russian DP-28 light machine gun became a very popular alternative to the LS-26.

The Degtyarev DP-28 may not have been as refined of a weapon, but it was much better suited to real combat. It was simple and reliable, and the 47-round magazine capacity was certainly appreciated as well. By the end of the Continuation War, Finland had some 15,000 Degtyarev light machine guns in its inventory, far outnumbering the LS-26s.

Today Karl and I had a chance to fire both weapons side by side (unfortunately, my trigger time on the LS-26 was quite limited, and I was not able to film a full disassembly of it). We both found the LS-26 to be quite a challenging weapon to use effectively, even without any malfunctions. The Degtyarev was a much more usable machine gun.

One other interesting takeaway for us was the remarkable effectiveness of the semiautomatics DP/DPM made by SMG Guns here in the US. It delivered probably 90% of the utility of the original fully automatic version, which is quite impressive. After this comparison, I would recommend it even more heartily than before.

In August 1913, the British War Office wrote to Sir Charles Ross requesting a sample automatic rifle for trials in the UK. Ross was able to submit a prototype in May 1914, which was tested at Enfield — but only fired 308 rounds before the test ended, suggesting that something important probably broke. The gun was a very strange looking contraption, whose Ross MkIII lineage is visible only in the bolt and front of the receiver forging. A long stroke gas pistol was added, and the action flipped upside-down. A large 25-round magazine was fitted, along with a thumbhole style stock that looks very similar to the grip of a Lewis gun. In addition to one example tested at Enfield in .303 caliber, one other model was send to the US for testing, chambered for .30-06. That is the gun we are looking at today, which came to the Canadian War Museum from the collection stored at Fort Knox in the 1970s and 80s.

Thanks to the Canadian War Museum for providing me access to film this extremely unusual Ross for you!

“… the Liberals’ oft-stated commitment to listen to the experts and the frontline workers fizzles when said experts and workers disagree with a preferred policy”

In The Line, Matt Gurney explains why the Liberals are so in love with a set of proposed rule changes that will do almost nothing to reduce gun crime in Canada and might even end up creating criminals of previously law-abiding Canadians … but it polls well in Liberal ridings:

Restricted and prohibited weapons seized by Toronto police in a 2012 operation. None of the people from whom these weapons were taken was legally allowed to possess them.
Screen capture from a CTV News report.

Talking about gun policy in Canada is tricky, because the debate is highly technical. The regulation of firearms in this country, at least in theory, depends on the specifications of the firearm in question. Mode-of-operation, magazine capacity, ammunition calibre or barrel-bore width, barrel length, muzzle energy — these are all the criteria upon which a firearm is classified into one of three categories under Canadian law: prohibited, restricted or non-restricted. Any Canadian who wishes to own or borrow a firearm, or purchase ammunition, must be licenced, a process which includes mandatory safety training and daily automatic background checks.

Prohibited firearms are essentially banned in Canada; a relatively small number are held by private citizens who already possessed them when the current regulatory regime was brought in in the 1990s. The government of the day didn’t want to get into the thorny issue of confiscation, so it let existing owners keep them under strict conditions. The vast majority of guns in Canada, and all new guns sold for decades, therefore fall into the other two categories. Restricted guns are generally pistols and revolvers, but also some rifles and shotguns. Non-restricted guns are run-of-the-mill hunting rifles and shotguns, though some sports-shooting rifles (used for target practice) are also included.

The above is all somewhat theoretical, as the regulations are twisted and pulled in a variety of ways to suit political ends, leaving a system that’s tortured and confusing even for those of us who study it. But it gives you at least an idea of how the system is designed. If you know guns, of course, you knew all this already. If you don’t, I wouldn’t blame you if your eyes glazed over a bit while reading the above. Without a basic working familiarity with all the terminology and technical specs and regulations, it’s damn hard to follow the debates over gun control. This is why I have to ask you non-aficionados to take my word for it: the Liberal proposal is really bad.

Well, actually, you don’t have to take just my word for it. You can read the NPF’s position paper, which makes at least some of the case. It notes, correctly, that “military style assault weapons” aren’t actually a thing that’s defined under Canadian law; it can therefore mean whatever the government of the day wants it to mean. True military style battle weapons — fully automatic weapons with high-capacity magazines and full-sized ammunition — are already effectively banned in Canada and have been for decades. Further, the NPF notes, firearms are used in a minority of homicides in Canada, a majority of those homicides are committed with handguns, and a majority of those killings are directly linked to organized crime or gang activity.

You’re probably starting to see the problem: Going after the guns that aren’t being used in the crimes, and taking them from the people who aren’t committing them, isn’t a public-safety policy. It’s a political gift to the Liberals’ urban base, where the proposal is popular and gun literacy low (those two latter points are not unrelated).

While the ban is almost entirely a political sop, it’s probably a good political sop, alas. I’m sure the proposal will be very well received in ridings the Liberals would like to hold or flip. But it’s still a stupid policy, even if it’s popular. The Liberals are proposing to spend tons of money on this. They estimate hundreds of millions, but recall that the long-gun registry came in about 1,500 times overbudget. And all to “ban” some of the rifles used by a segment of the population — licenced and screened gun owners — that’s been found to be the several times less likely to commit murder than those without licences.
