Purchased a complete 6.5 creedmoor upper assembled by them. Fired 3 rounds and all 3 stuck in chamber on the 3rd hat to barrow a cleaning rod to remove it as extractor ripped lip off the brass.got home and dropped a round in the chamber then the bolt carrier group then pulled out (no problem) and looking at the brass it has marked from the rifleings. Is this common with them? Waiting for a call back from them now to see about warranty
