Sup everyone, so here and there I basically know little things about converting blanks, but I never had really a good project, can someone please explain how to convert to .380 /32 /25 or even 22lr? In the past I would drill a hole and shoot the normal 9 mm PAK with a steel 4.5mm inside it and that's how I was dealing with converting bbs until my last ekol gediz exploded, now im with blow mini 09 ,blow tr 17 and a bruni (forgot the model name). can anybody please help with details how i can fully convert a pak pistol without exploding?

I'm curious how open bolt straight blowback smg bolt are in battery. Are blot entirely sitting on the end of a case or is it sit on a barrel or barrel retainer

Anyone who says that tape won't hold , never owned a slam fire. Went through quite a few shots with this thing

Please be safe, I know I'm probably the dumbest one in this sub. But for your own sake be safe.

I feel dumb asking here because google isnt super helpful.

Oh I loved her , but hot damn you had better hold on tight

Im currently deciding between making a .410 or a 12 gauge, but I simply dont know where to look or what parts I exactly need. Any help is appreciated, aswell as any tips or things you guys have learned making your own, thank you guys for your time!
