AR test.

You know, he mentioned that he replaced the Bolt carrier group in the upper.

I wonder, did he check the headspace after doing that???? What could having bad headspace do?

Bad head spacing makes it inaccurate. I think it also can cause more blow back.

Years ago I bought a CMP 30 carbine that was returned from Europe.

The underside of the handguard. And inside of the stock were badly charred. It was clearly on fire at some point.

Wish that one could talk.

It started life as a plain AR. But as he explained he replaced the lower with a M16 lower, and changed the bolt carrier group out with the SRC Relia-bolt carrier group. Those changes made it capable of full auto fire.

The argument could be made that since the lower is legally the firearm for the AR15 and the M16, the firearm in question was not an AR with an M16 lower but rather an M16 with an AR15 upper. To be clear, I know that the upper is what was really being tested, so I'm fine with it being called an AR15 test. Just sayin'.

It looked like the muzzle break just unscrewed and came off, and is it me or was he using wolf ammo?
Did it fail from heat or residue build up?

He mentioned at the start that they were using steel cased ammo, in order to stress the rifle more.

In the old days you'd just shoot full wadcutters outa yer auto-loader 9 or .45 and crow about.
But melting a machinegun is certainly fun.

Those last few mags the last two or three rounds in each mag was spitting fire back out of the chamber. Fun, but the kind of fun I enjoy best from a few yards away. I was expecting a kaboom very soon after the barrel started bending. I was surprised at how much longer it lasted.

Kaboom can happen.... But normally you don't need to check the headspace, 99 times out of a 100, the new bolt for your AR-15 would be good to go. I check, but never had one that was a no-go.

A bunch of twinkies feel left out. He should have used some and do his part in keeping them on the market.

Or maybe not so I can lose weight.

Personally I would have bacon wrapped it!!!!
