Wow that was scary. I had a gun that doubled or tripled once. I had to replace the major parts of the fire control system.

It's good thing that you had the presence of mind to remain in control and it keep it in a safe direction.
Good work. |

Happened to me on a new AR build. Somehow, I forgot to install the spring on the disconnector. Luckily, I always only load three rounds max when testing a new gun. The triple was ... unexpected.  |

It could also be the spring that activates the secondary sear. If the AR-18 is anything like the AR-15, it's got a double hook hammer and the rear hook catches onto the secondary sear which holds it in place to prevent the hammer from following the carrier forward. If the spring is worn or isn't working, the secondary sear fails to engage the hammer's rear hook. (Forgive me if my terminology isn't right).
BTW, good gun handling & I'm glad no one was hurt.

Try it on a Mark 19 when firing it free traverse
 Immediate action is sit down, shut up, hang on...unlike most other beltfeds where you can break the belt.

Before I knew better - I put grease on the hooks of the hammer on one of my Garands.
Surprise 3 shot bursts with 30/06 are a wee bit on the ouchy side. |

Hmm...another problem with the AR's?
  Glad to hear everyone was safe though. Were there any people around? |

A few years back, an armourer for the Orange County, Calif Sheriffs was killed because of a illegally converted and confiscated runaway Mac10, the gun kept firing after he let go of the trigger but it kept firing, and came around and killed him. |

We were out at the Kilo ranges at Lejeune and one of the medium helo squadrons was there for their quals. The had 4 M249s that they had to run a few thousands rounds through. I guess they didn't want to clean all four so they only shot two. One had a new guy who was actually qual'ing on it. The other was just the hose to waste the ammo allotment through. After a few belts it started to run away. The just kept linking ammo on and letting it roll to blow throughh the ammo. Fun to watch.
Ona side note they also had a helo door mock up on a trailer with a mini-gun on it and were qual'ing that too. That was a blast to watch. The noise and sheer volume of lead it throws was trully awsome. They ran all their guya through and then let some of the SNCO with the platoon I was attached to. Everyone took about a thousand rounds or so (about 10 seconds worth.) I was next on line and the Staff Sgt ahead of me hogs the f'ing thing until it runs dry( a good thirty seconds worth of firing.) "Sorry doc, I guess I just got carried away." And no way were they loading another tray up.  I still hate him to this day, and will for the rest of my life. |

Yep, I'm SURE that could never happen with, say, an XM-8 though, right? Afterall, the metal used in that fine weapon is incapable of wearing out!  What little metal is actually in the gun, that is.ETA - Glad to hear everything turned out OK, Lumpster! |

The M1 I used to have did this, also. Again, no grease on the hammer and mine was a 5rd burst. After the burst, the trigger group fell out into the mud on the range. Scary when you're not ready for it! As it turns out, either the disconnector or the hammer, can't remember which now, was worn and the disconnector wasn't catching the hammer. Bub |

I have heard of AR's slam firing. Would the safety ON have prevented that? I really don't know, just curious.

No, it's a free floating firing pin. It can still ignite the primer even with the safety on. That's why I'm an advocate of "don't load until ready to shoot," unless the firearm is being used for quick reaction self-defense. |

Well it looks like I am going to get off relatively cheap on this one. The cock notch is broken off my hammer. This was allowing the gun to slamfire.
Thank God nobody got hurt. Sure was a reminder to always keep it pointed in a safe direction. |

BTDT. Shitty FAL fire control groups and worn M-240G sears will cause similar situations. Takes all the fun out of it when you don't see it coming.

Glad you had it down range, but still be very careful. I met a guy at the range that lost a finger to a 1911 that did the exact same thing. He had his left hand on top of the slide and racked it back and it started going off, the recoil ended up lineing the gun up with his left hand fingers and took it off. He didn't even have time to move his left hand out of the way.

Good job man, you did good. I had a M11 go bang one time, and all I did was drop the mag. Gun was pointed down range. No one hurt. It's times like that you have to give yourself a pat on the back for following all the rules. And glad it was a cheap fix to boot!

My M-11/9 has run away a couple times, due to worn sear/bolt engagement surfaces. I brief all new shooters that such a malfunction is a possibility, and what to do if it happens (keep pointed downrange, control muzzle climb; it'll be over in a second!). Hasn't been much of an issue now that the slow-fire conversion is done, but it used to chew through sears pretty frequently.

This is unfortunately why some gun ranges put restrictions on how many rounds you can load in a mag. Its pointless i know, for the 0.00001% of guns that malfunction and run away. As always safe handling is the only way to be safe. Good job.

if you read the -10 for the MK19, actions on runaway for that weapon is to drop one of the charging handles to stop the bolt from going into battery |
