Tactitocool!!!:rofl::rofl::rofl: As much as I'm not a fan of the M Sucksteen/AR15. I've never heard of them doing that unless it was something to do with headspace being excessive or out of spec ammo (short necked/cracked brass). The man having several "Duds" (more likely light strikes) and hitting the forward assist several times suggest this. But I could be wrong. Either way it was still funny for no one got hurt.
A friend bought a bunch of ammo from a commercial reloader and had the same thing happen to him. He put 10 rounds in a mag and the third round blew the floor plate, spring, follower and the rest of the rounds out the bottom of the magazine. The case separated just in front of the web. It didn't hurt him or the AR. We weighed the loaded rounds and found three more that were loaded too lite. Instead of the 22 grains of ball powder the lite loads had 5 to 8 grains. The powder ignited all at one and exploded instead of burning at a controlled rate.
Reloading is very safe if you pay attention.
I load on a Dillon 550B but I look into every case before I seat the bullet. I shoot 25g of Varget behind a 69g match bullet and the powder comes up to the bottom of the case neck so it's easy to see.thats why every round I reload, the powder comes out of a spoon scoop on to a eclectic scale before being dumped into the casing. All my cases are measured and trimmed if needed. Each finished round is measured for length. Takes longer but I know it will go bang not boooooom.
Well, today was not a good day for a friend of mine.
We went to the rifle range this afternoon. I took my heavily modified Saiga .223 that I legally converted with all the US parts. He wanted to shoot it. He brought one of his ARs. We shot mine for a while and had no problems at all. I love this gun totally. Nuff about it though.
Next he brought out his AR. It was a Rock River (his #1 - his #2 is a Stag). He pulled out a 30 round mag and fired it off - no problems. Then he gave it to me to shoot and handed me a 30 rounder. He has been trying to convince me to buy an AR for a while.
I pull it up to shoot - and the first 4 rounds go off as normal. Then next trigger pulled scared the ever loving daylights out of me.
The gun bucked as normal, but then the shell casing (best we can figure) blew out. This shattered the bolt and carrier making it look as though it was a peeled banana. Lodged the bolt so you couldn't even separate the upper and lower. It then dumped all the expanding gases down the mag well forced the unfired rounds down the mag and blew out the floor plate, spring, follower, and the rounds on to the ground. After inspecting the destroyed weapon - we found that the upper had been buckled outward, and the ejection port cover would not close again.
The lower receiver had both vertical and horizontal stress fractures on both sides, and the area around the mag well was pushed out on both sides. The bolt catch and the magazine catch had both sheared completely off and hit me in the chest.
I will tell you I have never had a gun do that before - ever. And I hope I never ever will again. It basically took his $1000 dollor AR and turned it into a really expensive base ball bat.
Best we can figure is the factory loaded S&B ammo was loaded entirely too hot. It was S&B ammo, but there was a lot of the exact same ammo that had been fired two weeks ago by us through his Stag. He has found all the ammo and boxes and has the Lot #s, and found he still has about 100 rnds left - bet you can't guess what he's gonna do with it.
To those that only have a single weapon and boat loads of ammo for it - and plan to use it in a survival type situation - you might do well to purchase a backup weapon in the same caliber. Lest you have an expensive base ball bat and plenty of ammo to hit or through with it.
