Rifle Grenade Prototype

Area effect, Cold War, Rifle grenades, WWI, WWII

Following my last post about rifle grenades I thought I would show the prototype in a bit more detail.


The power plant for this system is a 40mm CO2 grenade. I have used the S-thunder mini grenades for this build but there is no reason the design couldn’t be used with a different grenade.

So, how to use! Open the chamber by pulling out the barrel.

Insert your loaded grenade:


Insert the barrel. Have the barrel face downwards to stop premature firing of the grenade. The grenade is locked securely in place when the polished steel is no longer visible.


And bang, you’re ready to go!


This prototype is for my M14, though I would love to make some more of these for other rifles. You can see the video with the initial test firing below:


Let us know what you think in the comments, on Facebook or email us on  enquiries.vintageairsoft@gmail.com. We will develop these for other rifles as they are requested so let us know if you want one!


UPDATE: Since this post was made initially, I have also started development of a rocket to go on it. The rocket in the attached video is only an initial prototype and improvements will be made as time goes on.

G43: Part Two

Custom builds, G43/K43, WWII

At the end of the last post on the G43, it looked like this:


The next piece of metalwork was the buttplate. This elegant pressed steel piece was ideal for the rushed mass production of late-war Germany but this apparently simple shape is actually very expensive to produce as a one-off.I decided to create it in two pieces, the side and back. These were then formed around each other into the correct shaped welded in place. It doesn’t look like much yet but it should clean up nicely!



The shape of the buttplate for the G43 is very different to the original M14. The stock shape had to be adjusted significantly, especially the back slope along the top.


Once the rough shaping had been completed, I cleaned the varnish off along the whole length.


I also welded the rear sight and chamber unit to the rest of the receiver.


Which could then be fitted roughly into place:


The eagle-eyed among you will see the hole at the back of the receiver. In an ideal world this would be filled with wood, but I was concerned that this would be a fragile solution. In order to make it look ‘right’ if not ‘correct’, I used a piece of thin sheet steel to cover this area, trimmed to shape.


A bit of real woodwork next, the upper hand guard is made from beech. The channel inside was routed out first, then the external shape planed by hand. I then marked out the vents in the side, cut the edges and removed them with the chisel.


Next, the rear sight. My first attempt wasn’t as tidy as I would have liked so I made a few tweaks to the design and had another go.Largely welded in the main, a little brazing secured the rear end.


A little cleanup later and the casual viewer would be none the wiser.


So, this is where we are at now:


I must confess that i have missed out a few steps on the way to this point.I made side panels for the receiver that fitted the woodwork. There is also a small arch of steel at the front of the rear sight unit that helps holt the top hand guard in place. These features will be refined for production.


This project has sparked a lot of interest and it looks likely that this model will be available as a kit and complete gun. If this post has inspired you to want a gun of your own, do drop us a line on enquiries.vintageairsoft@gmail.com to discuss or find us on Facebook.


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!
