Your barrel might be over gassed, to hot a load or the receiver is not square where the bolt is not aligning square with the barrel extension. What barrel length, gas port size/location and buffer tube/spring/buffer are you using?
Probably so. Barrel is well aligned with extension (sights all light up naturally, and lapping didn't do much as had a pretty uniform wear pattern when tried it). Brass is throwing to about 3:00, so doesn't appear to be over-gassed. That said, it is an adjustable carbine length gas system, so I might start playing with that all the same.
Also, I do have to give props to BRA. They responded in less than 1 business hour, sending out replacement extractors for free (i did not demand this btw); and with a note suggesting same - that I may be over-gassed.
I was hoping just removing the O-ring, which folks said would fix it, would fix it. And I was hoping lapping the upper, which folks would say fixes it, would fix it. Neither of those helped. So next step is to start adjusting the gas-setting. I hate doing that though, since the gun runs 100% reliable otherwise. But, here we are.
