I just found this on Break, so I am sure many of you have seen it. www.break.com/index/m16-back-fires.html Just before the failure you can hear someone say, "I didn't load these, (name) did." and then the mag gets blown out the bottom of the receiver. So do you suppose it was a double charged cartridge? |

If you get an overcharged round with your AR, what needs to be inspected, assuming its not as bad as this one and only the mag bottom blows out? Barrel lugs, bolt & carrier, chamber, inside of upper, mag well, inside of lower, and of course the bore? I'd look for cracks & broken parts, bent metal. What else? I saw this happen with the guy next to me at the range, and he had black smoke curling out. Made me wonder if he had CLP somewhere it didn't belong. I told him not to fire it until it was checked out. He said it was commercial reloads.

+1 Also, I thought there might have been a discharge as he was putting it down after the first attempt, but then I figures it was an optical effect from un-zooming the camera. |
