M4 assault rifle with M203 grenade launcher, both of which fire.
About this creation
Having built the first one, I thought I could do better with the general shape of the model, so I rebuilt most of it. It still used exactly the same firing mechanism for the gun (although not for the M203 grenade launcher, which was significantly improved).
I've been inundated with requests for instructions recently. Sorry, but not only do I not have time to make instructions, but also the models have usually been dismantled by the time people ask.
Awesome design, could you send me some pics of the trigger assembly and maybe some instructions on how it works, I've been working on my own AR but I havent been able to find a good firing mechanism that works well other than the one I already have which isnt that great. Well anyway good work and keep it up man.
