Rootshoot, Damn, your number 2, ejector too long sends chills up my spine. I have less than 100 rounds on a build. Alexander Arms Upper and barrel. The first 50 rounds or so O.K. Now the first round (sitting on the right side of the mag) feeds fine and shoots fine. The next round feeds about half way to chamber, but cocked to the side (where the case doesn't sit in the bolt). Different mags do the same thing. I installed a bolt "D-Fender" rubber gasket..... no change one shot then jam? Anyone have this problem?
