Finally got my xcr in 5.56 out on the weekend, put 20 rounds through her and went to adjust the gas valve, shoot again.. And no ejection, go to turn the gas back up and no gas valve lol I sent it down range and it was gon for good. Now I'm stuck with a 2400$ bolt action gun until my new valve gets here. I want to punch myself in the face
Hate to be the one to say it......Locktite! Happened to me too. I was lucky to not lose mine though
