Anyone have problems with the charging handle bolt loosing up while shooting? Put 40 rounds through my 4095 and the bolt loosened up. Second time it happened. Not sure if I'm not tightening it enough or am I going to need a little loc-tite. Other than this the 4095 is shooting real nice. Did not take long to go through the 40 rounds. Shot a mix of 180 gr Federal, Blazer and Speer HPs.
