This is my Bulgarian AK 74 semi automatic rifle that I'm bump firing from the waist using my belt loop to secure my thumb in front of the trigger in order to make it full auto. This gun shoots a 5.45x39 cartridge which is much better than the 7.62x39 (AK 47) cartridge in every possible way! You can use this technique on most any semi-automatic rifle/shotguns that have a modest amount of recoil.
