M4/M16's have the same floating pin slamfire problem. There were a couple AD's down range until guys started rotating rounds in the magazines after missions. But the bolt is always fully locked by that time.
I haven't pulled an M14 apart in a few years, but by the time the hammer can reach the firing pin the lugs should already be engaging, right? Like I said, its been about 8 years since I've taken one apart.
Freedom's just a word. If I'm gonna die for a word, my word is jello...
