Armalite M15 10.5" all factory except the stock and the troy break... ruag 63gr. ammo, standing at 25 and 50 yards... we used GI mags and LAR pistol mags. It works for the skinny kid and his dad who are both smaller than me. the other unit is the exact same, except a few years and 1500 rounds older, they both fire for everyone except me. They jam on the return of the bolt most of the time and some times fail to extract. I do have a love for short barrelled shotguns and slugs, so I do tend to squeeze the hell out of anything I shoot. Maybe I should soften up a bit... I also use a .22 conversion in it, that works like a hot damn...
This is my first AR platform,,, maybe I should just get use to it.
P.S.... I have shot every kind of semi you can think of and I have never had this issue.
More thoughts??????

Here's my take on it ... get yourself a heavy extractor spring with the black insert and add a D ring to it. Your problem will go away.
Your extractor may be ripping off the case rim during erratic extraction. Check for torn case rims. That Ruag stuff is pretty potent fodder.
