Have a 6.5 grendel AR-15 that the last time I shot it failed to eject a round. Afterwards i noticed that the extractor was broken. I replaced the entire bolt and it would not go into battery. I thought I had messed up and ordered the wrong 6.5 grendel bolt so I ordered the other style grendel bolt, but that one also wont fully go into battery either. Anyone have this experience before?
