I recently put together my 10.5" upper after getting my stamp back. While test firing it failed to feed on multiple occasions. It seems as though the bolt is not moving far enough back to strip the next round out of the mag. I tried several different mags to no avail. I checked the gas system and everything is functioning as it should.
I tried an H and an H2 buffer with a Wolff power spring. Neither solved the issue.
Any ideas?
Thanks,
