| I noticed a dimpled primer in in a round in one my mags, so I loaded a primer into an empty cartrige and dropped the bolt on the dummy in the chamber; Upon removal, found the primer was dimpled. Is this common on the AR's? Shoujld I consider a titanium firing pin, or would the lighter pin agrivate the situation? |

I've known about this but I have a question, is there any danger of setting off a round if these rounds are repeatedly chambered and unchambered? I'd say minimal. After reading your question, I took that "dummy" cartridge I made and dropped the bolt on it a dozen times with the muzzle pointing down for max effect and no pop. after the dozen times, pulled trigger and pop. Below is what the primer looked like after the dozen bolt drops. Now that was with a Federal Match primer. Suppsedly, CCI's are softer, which could change things. Can't tell you about factories, since I'm not going to try it on a live round or pull apart a perfectly good round, but I'd GUESS that the factory primers in military ammo are fairly hard. Could be wrong, though.

Hey, my brother's FS2000 started doing that right before it blew up in his face! Might want to make sure you wear your eye and ear protection from now on... How bad was damage to the FS2000? Do you have pictures of damaged rifle? How bad was your brother hurt? |

Your brothers rifle was not an AR15 and as such your comment does not apply here. To the OP, your rifle is the same as everyone elses. As has been said the free floating firing pin hits the primer during chambering and leaves a small dent but not nearly enough to set it off. If it bothers you, rotate your round in your magazine if it's a duty weapon where you constantly rechamber ammo. |

I've been told that the milspec for 5.56 ammunition requires a slightly harder primer than some civilian ammo, because of that condition. Don't know how to verify or refute that. You are correct. CCI #41 and Wolf Small Rifle Magnum primers are two such primers. |

How bout this question...same situation...chambered round then removed and noticed the bullet has some scaring/scratching from being chambered. Is this normal....i assume its form the feed ramps and chamber etc....
Do you think a previously chambered round that has a little knick or groove in the bullet could change the accuracy of said shell in the future when its actually fired? |

Haha, haven't seen this one in a while.
I've never seen one go off, or heard of it happening. This goes with out saying, but ALWAYS HAVE YOUR WEAPONS MUZZLE POINTED IN A SAFE DIRECTION WHEN CHAMBERING A ROUND. I would sure as fuck hate to be that one unlucky bastard who got a soft primer. |

Nothing could happen. Go ahead and leave your sight protection at home, you'll never need it. Nothing whatsoever to be concerned about.
