Was shooting at the range yesterday, when suddenly my semi Bushmaster XM15-E2S decided to go full auto. I immediatly let go of the trigger and cleared the weapon. After much consern I inspected the rifle back home, and didn't find wery much that would cause the rifle to go FA. Then I discovered the spring between the disconnector and trigger had broken, and collapsed to half it's size. The rifle is only a couple of years old and have only been fired a couple of thousand rounds, so I can't see any exessive trigger or hammer wear. Could the breakage of the little spring be the reason for my Bushmaster going full auto? -jerv |
| No joke, what would a person be charge with if that happened?? Could you prove it broke and had not been tampered with?? I sure wouldn't won't to find out personally but just curious. Has there ever been anyone charged with having a FA weapon and they proved it was not their fault and charges dropped?? I'll bet that would be a night-mare in the making. |

He never said anything about testing. He said the rifle had a couple thousand rounds through it, and he went shooting. Your rifle should have had a notched hammer and exposed firing pin shroud which prevents this from happening if the spring/disconnector failed. Either this rifle is not a factory build and someone built it using improper parts or you hit the very magic spring tension that would hold the hammer untill the shock of the bolt carrier closing would shock the hammer off the disconnector. |
| Guys, I'm a newbie, but have a quick question. Please forgive my complete ignorance of the mechanics of the AR trigger system, but doesn't the condition described above constitute a "slam fire"? If so, then that's an enormously dangerous situation, for both operator and bystanders, no? |

Quoted: doesn't the condition described above constitute a "slam fire"? No. A slam fire is caused by a stuck or protruding firing pin that detonates the primmer as the bolt "slams" forward. Kind of hard to happen with an AR-15 as the bolt always comes forward, out of the carrier and if the firing pin were stuck this action would loosen it. It's not impossible but highly unlikely that it would "run away" through a whole magazine. Edited to add that the stoppage when he released the trigger indicates a fire control malfunction. |

The rifle is an XM15-E2S LEO 14.5" carbine right from the Bushmaster factory with no modifications. |
