I have this LMT upper with RRA SA BC group. The barrel is 14.5 with Vortex. Once in a while I have extractor problems like the round not exracting properly. Last trip to the range my mag ran out and had a few rounds on the bench so I dropped one at a time let the bolt go and fired. The Bolt dropped the spent casing on the follower like I put it there when it was live. It failed to extract the shell casing.:confused:
Checked my mags no problem with any of them.
What is up with this bolt or am I over looking something.
