LMG25: Build 1

The LMG25 is a really weirdly formatted gun, but with a Sten and some modifications I’m hoping to make something really interesting and unique.

As ever, this started with a load of research and design work. There aren’t too many parts to this compared to some of my builds and they nearly all attach directly to the receiver. The first step of construction was to make this receiver, which I made a template for and centre punched for the drill, before cutting the space needed for the donor.

The welding begins with the mock-upped ejection port and the trigger grouping/pistol grip.

I also cut a hole for the magazine feed.

The magazine well has an awkward and distinctive shape, so it is being 3D printed and will be mounted with metal plates and screws to the receiver.

In place it fits quite nicely! This replica takes AK magazines which look the part well enough from a distance.

Onto the stock. I cut it out in the usual way from the blank, but I can’t cut out the action recess in the usual manner due to the awkward lump at the front of the stock. It would have been possible to have this as a separate piece but it’s not a major issue to work around.

The pistol grip unit is, fortunately, an entirely separate unit. This means making it is a lot easier than a one-piece pistol grip/stock. It somewhat resembles some of the early semi-auto conversions of bolt-action rifles in this respect of its design.

There is quite a pleasing curve to the back of this pistol grip which is easily missed.

This means that all the major working parts are in place. The next important step is to get the working parts actually working! Then we can enjoy the detailing, sights and bipod.

The LMG25 Furrer

Cold War, Custom builds, Inter-War (1918-1939), LMG25, Machine-Guns, Weapons, WWII

The LMG25 is a Swiss Light Machine Gun adopted, as the name suggests, in 1925. It is a real oddity, even for a time when LMG designs were far less standardised than today.

This Swiss soldier will get a very warm thumb if he opens fire now.

It was developed at Waffenfabrik, Bern by Adolf Furrer over seven years and was produced until the end of WWII. It served into the 1970s with the Swiss military, so must have been a pretty serviceable firearm to have hung around for so long.

So, why is this an oddity? Well, the magazine is on the right-hand side, when most side-feeders (though not all) feed/fed from the left. There was a monopod at the back for support during sustained fire which wasn’t an uncommon idea at the time, but this could be moved to the front and used as a foregrip, which was.

Monopod used as a fore-grip in the assault role.

But most interesting of all, this is a toggle-locked design. There are very few toggle locked guns due to the complexity and expense of manufacture as it is. There are even fewer rifle-cartridge toggle-locked guns (especially that went into production). As well as the high level of accuracy required for these to function, they also need to have a very strong recoil spring and a conventional toggle-lock doesn’t provide great purchase when cocking. The LMG25 has a separate operating handle to aid with this.

The LMG25 is also interesting because as well as being toggle-locked it fires as you would expect a support weapon to do, from an open bolt. It is the only firearm of which I am aware that is both of these.

lmg25-8

The open toggle. When opened, it kicks open the two-part dust cover. Anyone familiar with the Luger will recognise the parts of this.

Just in case this wasn’t different enough for your liking, it is also unconventional in that the barrel does not stop once the toggle is broken open but keeps moving backwards. The shell is still ejected as the toggle moves much faster than the barrel.

The dust cover in the closed position below, and open above. It is in two parts to fit around the toggle. Very Swiss. 

In spite of all this strange-ness and the alleged complexity of toggle-locked guns (over-egged by those who have spent no time with them) it is very simple to field strip. One large nut at the back of the receiver allows you to remove the recoil spring, then pull out the barrel assembly. What about the bolt? Well the bolt/locking mechanism is all part of the barrel assembly on this so the whole lot pulls out together. Neat for cleaning in the field.

While beautifully made, this type of gun never really caught on. It served the Swiss well, where money was no object for a relatively small army but for any other military the expense would have far outweighed any advantages. 

lmg25-3

Of course due to never being adopted outside of its home country, which didn’t participate in any conflicts during this period (or ever since about 1847) it never saw active service so it is difficult to say how it would have performed. 

 

If you want to see some footage of the LMG25, Ian at Forgotten Weapons has a nice video talking through one in Belgium here:

He also has some awesome footage of another LMG25 firing, including a lovely bit of slow-motion:

Vintage Airsoft will be building an LMG25 over the next few months with progress posted up here.

The bolt-action rifle

Cold War, Custom builds, Products, Rifles, War on Terror, WWI, WWII

With the advent and popularisation of centrefire ammunition, militaries around the world welcomed in a new era of accuracy and power. As smokeless powder replaced other propellants, a higher accurate rate of fire became not only possible but necessary to overwhelm the enemy.

The weapon of choice most armies turned to to arm their infantry was the bolt-action rifle. The best known being the British Lee Metford/Enfield series of rifles, the German Mauser mechanism and the Russians welcomed in Belgian firearms designer Leon Nagant in order to pilfer his feed mechanism! (OK, this story is a lot more complicated than that but I won’t go into that here).

There are advantages and disadvantages to all these mechanisms, the Enfield by all accounts had the highest rate of fire, The Mauser is a very solid, reliable mechanism and the (Mosin-)Nagant which is a solid mechanism with a good reputation for accuracy.

All of these rifles served their countries well throughout their service lives. Consider that these mechanisms were all designed around 1890, the Lee-Enfield served the UK until around 1990 (100 years of service) and was still being used by India as of 2010, the Mosin-Nagant is still in use by a number of countries. The Mauser is harder to pin down on military use but it is still widely used for sporting rifles.

So it would be fair to say that these rifles deserve a fitting tribute in Airsoft too. Although good quality bolt-actions are available they are not often suited well to the Vintage Airsofter. Some are gas-powered and struggle in cold weather, others load through the fore-grip rather than the magazine so lose out on authenticity and ‘feel’ when being shot and some shell-eject which although look good are not practical for skirmishing.

Here at Vintage Airsoft we are developing a spring mechanism that will feed from a magazine in the ‘correct’ location. If you are interested, do let us know as we are looking for ‘backers’ to help us speed up the development of this system. It isn’t far off a functioning prototype at this stage and once it is functional we will be able to produce the main bolt-actions of the Second World War and many other rifles besides.

The ‘realism’ kit, and a teaser

Add-on kits, Sub Machine-guns, WWII

20141125_173616

Some of you may have noticed that in the MkV post, my Sten looked a bit different from the standard ASG Sten (and not just because of the load of wood attached to it!). Due to the shape of the AEG internals, it is not possible to fit a real steel spring so I made up a jig that would allow me to bend some wire to a consistent angle repeatedly.

This created a wire zig-zagged like half a spring, but flat. Pressing this along the outside of the Sten longways bends it roughly to shape for the inside of the gun. Although it can be inserted through the back of the gun, I found that it made the ‘spring’ get stuck on the back of the gearbox. Instead, I removed the fore-end and slid it in backwards, easing it along with a pair of pliers.

The fake bolt-carrier I used is actually made from a sardine tin lid. The finish on this is of course rustproof within reason, making it ideal. Again, I bent it to shape outside the Sten and just slid it in through the fore-end. In the longer run, I plan on replacing this with a piece of brass sheet and offering it as a kit, once I have made a cover for the rather ugly hex-bolt that comes with the original gun.

 

 

And why is this post a teaser? The first picture is a clue to my next project for release…
