Jeffery Boring Some wander how a coat hanger could possibly make a gun full auto like its magic . It’s a simple thing that just releases the hammer right as the bolt starts to close . The bolt face is already closed its traveling ahead of the bolt and rotates into position. Sks has a tilting bolt the face closes on the bullet then the back of the bolt drops and trips the release. It’s simple ppl then always say it’s out of batter it’ll blow up in your face. No it’s not it’s closed up tight it’s not slam fire or anything else. If u tell em how simple a open bolt is they don’t know what to say
