| went shooting this weekend, shot around 500 with 3 failure to extracts. i was shooting 55gr fmj pmc through a 16 inch dpms. i didn't have any problems removing them once i dropped the mag and cycled the bolt manually. has anyone else had this problem? |

New rifle? Spend cases left in the chamber or dropped from the bolt face before the end of stroke, or the bolt never coming back at all? Upper bearing surfaces of the rifle lubed correctly with CLP to begin with, then maybe re-lubed (B/C at least) again at the 300 round mark? |
