Had one today using Wolf. Hit bolt release, boom. Any one know if this common with Wolf?
Never had one before |

Quoted:
I've always equated slam fire with firing pin problems, not ammo. Could be that the primer projected past the head of the cartridge. The bolt going into battery would certainly detonate it without the firing pin making contact. As for the OP's situation, I'm leaning toward the firing pin being more relevant to the cause of this situation. |

Quoted:
Whens the last time the bolt and firing pin were scrubbed? How old in the rifle? I agree its most likely a firing pin issue. But a high primer is also suspect. Fairly new build, CMMG piston, prolly less than 500 rounds through it. Piston puts next to zero carbon in the BCG. |

Slam fires are generally related to the following problems.
1. Ammo. Usually a high primer. Inspect the ammo. 2. Firing pin. A broken, out of spec, or stuck firing pin strikes the primer. Inspect the firing pin for broken or jammed pin or for a long firing pin. Jams can be caused by fouling or foreign matter like a primer fragment stuck in the bolt firing pin tunnel. 3. Trigger problems. The bolt closes, the hammer fails to stay cocked and drops. Inspect the trigger assembly, especially the action of the disconnecter and hammer. If the disconnecter doesn't have enough engagement with the hammer the hammer can fall from the bolt closing shock. If the hammer-trigger interface is too light or is insufficient bolt closing shock can cause the hammer to jar off and drop. Most common cause of slam fires in most rifles: A defective trigger assembly, usually caused by trying for a lighter, shorter trigger pull, or failure to properly adjust the assembly. |

I'd put good money on something being either out of spec in the trigger group you purchased, or else it was assembled incorrectly somehow. Have you checked the FCG to make sure everything is kosher? |

It's a RRA two stage that I took out of a different AR; have not noticed anything but I'll take a look. |
