I have an ar 15 with a cmt/Stag milspec bcg that when the bolt closes on a round in the chamber it leaves a small dent in the primer. Kind of scarey considering that I noticed it while chambering a round indoors, and then ejecting it. Anyone have a clue as to what might be causing my problem? Thanks in advance. |

As has been previously stated, the occurence is normal and in most cases is nothing to worry about. HOWEVER, there have been cases where the floating firing pin has contributed to slam fires. It never hurts to say it again... NEVER LET THE MUZZLE COVER ANYTHING YOU ARE NOT PREPARED TO DESTROY Especially when chambering a round. Especially when indoors. Safety first. |
This is normal for floating firing pins. With few exceptions I never chamber live ammo to test functioning. |

Hey the site is back up, and thanks everyone for your responses. After posting my question, I primed some empty cases and chambered them in my other factory built rifles, and found that they all do the same thing. Previously I had never noticed that little primer mark, probably because unfired ammo does not stay that way very long around my house.

Make up some dummies to use for function testing. Ten dummies costs you ten cases and ten bullets and can save you a WORLD of grief. I once got to have dinner with a renowned gun writer who was an aficionado of a particular self loading pistol. He told a story about how he'd decided "just this once" that live rounds were ok to function check a pistol. He was in the basement and cycled a few rounds through the gun without incident when, JUST AS HIS SON WALKED PAST THE BASEMENT WINDOW, BANGG!!!!! he put a nice little hole in the wall right next to the window. His son dug the slug out of the wall and had a tie tack made of it for his dad, the "gun expert." Lesson learned by him and me. |
