Rifle grenades-Introduction

Add-on kits, Area effect, Cold War, Rifle grenades, Weapons, WWI, WWII

Firstly, apologies that it has once again been an age since I last posted. I’ll be updating what I have been up to over the last month this week.

A slight diversion from the usual this time, the rifle grenade was developed in the early 20th century to allow soldiers to launch grenades further than they could throw. This technology would fill the gap between hand-thrown projectiles and small bore mortars until the 1970s, when dedicated grenade launchers became popular and the 1980s when underslung grenade launchers became widespread.

The rifle grenade first saw extensive use in the Great War where the high trajectory required to land a projectile in the enemy trench and short-medium ranges between opposing forces made them an ideal area-effect weapon where mortars were not available.

In airsoft, gas powered 40mm grenades are popular with modern players who are able to use them for room clearance and area-effect. However the M203-type launchers are entirely unsuitable for WWII and other pre-1970s era airsoft games. Anyway, this is my prototype answer to those who want to add a bit more ‘oomph’ to their semi-auto or bolt-action. More to come on this concept.


I’d really like to build these for WWII airsoft rifles, if you would like to be a test subject let me know! Our email is: enquiries.vintageairsoft@gmail.com or you can contact us through our Facebook page!

G43: Part One

As regular readers of this blog and the Facebook page will be aware, many of the projects begin with some intense design work and a lot of laser cuttings! I was particularly looking forward to getting these as it was my first venture into mass-preparing parts for hand folding.

I tend to run several components’ production in parallel so that i can be working on one as another cools, but the first job was assembling this little former:


This shape allows me to very accurately bend the front sight hood by hand.



This done, I did much the same with the barrel band and drilled them so that the unit could be assembled with the sight post in the middle.



The one screw loosens and fits the whole unit. I may do some more work on the appearance of the foresight itself but it’s not bad as a first attempt!

Next was the front band, the part that ties the top and bottom of the stock together.


Again I made formers, this time out of wood, for the strips of steel going around the woodwork. These were then viced with the plates that corresponded to them and welded in place. I rather conveniently had a piece of steel pipe exactly the same diameter as the barrel of the M14 I’m working from in order to assemble these parts.

Clean, polished and fitted to the gun for the first time. I must confess that even I was surprised at the first fitting with no modifications needed at all!

With the receiver came a lot more bending. Each panel was hand bent over a piece of 38mm steel tube.


Once the curve was pretty close, the appropriate endcaps and features were welded in place, holding the exact curve needed.


I then had to fit it to the gun:


Clamped in place, ready to go! At this point my angle grinder gave out. Typical.
_DSF5977A quick trip to Screwfix later and I could get to work removing the receiver unit from the gun. I had hoped to keep this intact but it turned out to be integral to the gearbox housing so it had to go!


Once the main part of the receiver was gone, I could trim away the remainder of the receiver that was in the way. At this point I had to make some adjustments to the stock in order to fit the disk at the back of the gun. A straight bit cut away the space needed and a small channel where there would be a curved lead in like the original G43.



Cut away stock, also trimmed down at the front for the top guard. I will need to make a filler piece for the lead in to the receiver as the stock was pretty hollow at this point to fit the gearbox in.

The last photograph shows the fit of the parts so far. I’m happy with the back two, but I will need to modify the rear sight and chamber to fit over the hop unit/barrel mount. I will be putting strips of steel down the edge of the receiver to help it fit absolutely spot on.


So far this had been a really fun build, it’s nice to be able to focus on the cosmetics for a change!

G43: Hitler’s Garand

Custom builds, G43/K43, History, Weapons, WWII

Firstly, apologies for not posting in an age, I’ve been too busy building and not doing enough writing!

The Farquhar-Hill, an experimental British semi-automatic rifle.

Semi-automatic rifles were not a new technology by the Second World War, indeed they were available from the 1890s for those who really wanted to stay ahead of the curve: this not being all that long after the bolt-action/magazine combination was widely accepted. In spite of the seemingly obvious advantage of semi-automatic fire to the modern viewer, it took some time before it was widely adopted.

In the interwar years, most of the major nations experimented with semi-automatic rifles though only the US adopted it as their main rifle technology. That said they decided to sit out the first two years of the Second World War so had a bit more time to faff around.

The advent of the Second World War actually put back the adoption of semi-automatic rifles in Europe as there was a sudden need to re-arm without time for developing the new weapons. As a result, pretty well every nation went to war with the same rifles as they fought the Great War with.

On the Eastern Front, German forces generally made good headway against the Soviets, thanks mostly to their major superiority in the air and mobility. One of the few sticking points was where they came up against troops armed with the SVT40 and SVT38 semi-automatic rifles.

As a result, the Wehrmacht put out a tender to German manufacturers for a semi-automatic rifle:

  • No holes for tapping gas for the loading mechanism were to be bored into the barrel
  • The rifles were not to have any moving parts on the surface
  • In case the autoloading mechanism failed, a bolt action was to be included

The latter two make some sense even to modern eyes. The former was the result of paranoia that tapping gas for a reloading mechanism would sap the power of the bullet. The G41 used the ‘Bang’ system instead*. This system uses a ‘cup’ at the muzzle end to capture the blast and move the long operating piston. Sadly this system proved sensitive to dirt, hard to clean in the field and suffered from exposure to the corrosive chemicals used in primers of the era.

As a result of these problems among others, the G41 has earned a reputation of being possibly the most unreliable rifle of the era.

This was not good enough for the Wehrmacht who had the rifle redesigned, using the Tokarev system for inspiration.

The result was the G43, a far more effective rifle, but the Germans still weren’t quite happy! G/Gewehr meant ‘long rifle’. At only two centimetres longer than the Kar98k the Germans felt It was too short to be ‘gewehr’ so in time renamed it K43.

Beyond this the rifle stayed much the same for the duration of the war with mainly minor alterations. A scope rail was added and featured on most production rifles so that a Zf4 scope could be used, though this was only special issue.

Over the next month or so I’ll be converting an M14 into a G43 lookalike, as usual sharing the results here!

Fun facts!
  • Later in the war some last-ditch K43s were produced to run on the 8mm Kurtz intermediate round and use Stg magazines
  • The Zf4 was the ONLY scope used by the Wehrmacht in WWII on the G43
  • German soldiers were instructed to make semi-automatic rifles unusable if capture was imminent, as a result many examples are found with broken butt stocks
