a little fix to make it more realistic:
1) Recoil on arms. make the hands gone backwards, sort of.
2) Random casing fall. It’s not too synced cus the bullets gone randomly.
3) Muzzle flash. you can see them sometimes, and sometimes not..just like the misfining system on a turbocharged car.
4) Nice Simple history base you used there…but i haven’t see the channel for a quite long time.

Sorry, kinda enthusiastic on guns and bullets.
