Questions & Answers


hahaha incredible, I am trying to make my own full auto gun for days and now I see I created a mechanism that you came up 2,5 years ago!

Yes; the gun will not work if you don't.

Does the Friction Mech cause recoil?

Yes, quite a bit which i think is cool.

coool. i'll have a look. btw i'm making a ppsh with your idea. hope that's alright. it has a drum mag that actually works (not like the real one though.). it's just a normal mag with 2 semi circles on each side lol

OOPS! Sorry i forgot to say. i gave up ages ago lol. it looked so ugly LMAO. I've gone back to gaming, uploading vids of them & listening to dubstep =P

do you need to cut the rods?
