This picture was sent to me today from a local gunstore that is run by a retired LEO. The owner purchased this at a local gun show recently. He bought into the “all AR’s are the same” myth. Look closely and you will see the “D” marked bolt.
The person in question was firing 5.56 ammo in the weapon. I was told that he also received some small injury to his arm. This is why it is important to realize that if you have a questionable barrel you need to stick with .223 ammo.
Looks like the failure was in the carrier do you know exactly what happened?
Firing 5.56 ammo in a .223 chamber. No, it didn’t fire out of battery as that cannot happen with the AR15.
I’m all for advocating the purchase of quality AR’s, but what exactly was the mode of failure? As the bolt appears to be intact.
I wonder if it was XM193… The combo of the two extremes wouldn’t be good… (DPMS/XM193)
IG, may I have your permission to forward that photo to someone that is contemplating an AR purchase?
They do not have access to M4C, due to corporate firewalls.
Thanks for the reinforcement as well.
I’m curious as well. It doesn’t look like a typical failure. The carrier seems to be what failed, normally several bolt lugs are missing and the barrel extension cracked.
Junk.
DPMS :suicide:
A picture is worth a thousand words… Of why you dont buy junk and always use the correct ammunition in your firearms. Hes lucky to have only sustained a small arm injury.
This is Exhibit A to counter the whole “all ARs are the same” nonsense that the people who work at gun stores usually say.
Is the “D” marked bolt what gives this away as a DPMS?
Ironically, the Bolt wasn’t what failed…
Cartridge Case Failure…
Sure.
A. The gun was purchased as a complete DPMS carbine.
B. All DPMS that I know of have “D” marked bolts.
C. I highligthed it in case any of the DPMS boys showed up claiming it was a conspiracy.
How does or can a case fail if the bolt is in battery and lugs are intact along with the chamber and barrel extension?
so that only happens in dpms rifles? would it happen if he was shooting .223 ammo?
Blows out the extractor cut.
So is the speculation on this being a tight .223 chamber and a .556 round loaded on the hot side?
Guys,
This is a well known issue with any of the companies that play the magical shell game.
If you have a one of those brands and you are not 100% of the chamber, get it checked or stick with .223 ammo.
