>>211849121>unless you have acces to spare parts and ammoNeggen, you can't be serious. There's a thread on /t/ with parts for almost everything. There must be ammo STL files there. Just put the gunpowder in and follow those instruction videos on Youtube to make your own ammo. It's not that hard.
About the spare parts, I don't know why you would need them for a cheap plastic immitation.
