Ever wanted a bullpup M4 or got an old one just lying around then this is the kit for you. Why not convert you classic M4 into something a bit different. 


This is a 3D printed conversion kit for m4a1 aegs and should be compatible with G&G, Tokyo Marui, Cyma and ICS rifles.

As this is an after market kit we cannot guarantee compatability with all M4 Rifles. Please check all parts for fitment before fitting as once they show signs of wear we cannot take them back. The same for any damage caused by fitting the parts to an incompatible rifle.

Basically avoid the hassle and get us to do it, if we break it that's on us!

Please be aware that your M4 will require significant modification to go in to this kit including removal of the grip hand guards and stock.


3D printed parts are not as strong in their fine details as injection molded parts, over tightened screws etc will void your warranty, we recommend going to your local tech for installation, or give us a call! Please also note, the materials involved in manufacturing these do not fair well in the heat, do not expose them to heats in excess of 50 degrees C as this will cause heat damage to the parts, yes even in England, a hot car will get up there!

Gun not included!
