Why?

From the FTFs and the constant use witht he second mag of the charging handle and forward assist - especially since he felt he needed to push the charging handle forward (? ? ?), something was clearly wrong.

I don't think it had anything to do with the forward assist.  I think he was just hitting it because he has been told that is the way to us an AR.

He had a miss fire with the first mag, and then the series with the second mag.  I think he had a bad reloading experience.

Did you also notice that Einstein determined that these were all bad primers simply by racking the action?

I had a similar thing happen at a match.  For me it was over pressure loads.  Cost me $500 to rebuild the upper.

I think he had a broken part in the bolt which prevented the bolt locking up, which caused the failure to fire.  He forced the carrier in position but it did not lock up.

When he fired the cartriage was not completely in place and ruptured possibly breaking the bolt and carrier.

The blast focused down through the magazine as it should.  He is a very luck knuckle head.

 Did any one else notice that he
hit the forward assist, pulled the charging handle, then tapped the bottom of the mag, WTF ?
right actions, wrong order, the forward assist had nothing to do with his Kaboom as the round he "assisted" was then ejected.
With his crappy IAD technique  it is possible that the the bolt wasn't fully seated.

And this a perfect example of why Oakleys dont count as proper eye protection.

I don't know shit about AR's, BUT, I can recognize an IDIOT from way back here!  

This guy should never be given a firearm without proper and extensive supervision and training.

"When in doubt, get a bigger hammer!", don't work in this industry!

i was expecting that to happen when he kept hitting the forward assist at all the wrong times

Maybe I'm wrong, but I thought an AR firing pin COULDNT reach the primer until the locking lugs were in place...  :-\

The bolt kinda "cams" around and moves back into the bolt carrier so the firing pin reaches right?

Soooooo, the explosion had to happen "in battery".  Sooooo, even with a WAYYYY overpressured round you couldnt blow the gun up like this without a clogged barrel?  JUST GUESSING!  :-\

Don't know if I can blame the gun when the operator was an obvious idiot.

I agree. 

Still dont like even the idea of a forward assist though.  The only thing it can accomplish is to make a jammed gun into a VERY BADLY jammed gun.  OR possibly cause the thing to blow up in your face!   :(

Either way it can really screw up an otherwise pleasant trip to the range.  ;D

I don't think I have ever had a problem that was resolved using the forward assist.

I have seen some CREATED during the forward assist, however.

I've never needed to use the forward assist on my ar, but I would love to have on on my 1911 and 2011.  In the run and gun game it is common to have a slide not go all the way into battery, and once you get used to it you just slam the heal of your hand on the back of the slide.  Once in a while it takes a little meat out of your hide.

I've been told by a couple of regular three gunners that under the same conditions that cause it in a pistol it will happen in the rifles.  When your just an eighth inch out of battery it would be nice to just reach up and push with your thumb rather than racking another round in and hoping it goes into battery.

The bigger question is what was so tight that he needed to hammer the assist like that?  Since he didn't seem to really check it out, I'm assuming that he was just hammering on it.  Like I said before, I've never needed it on the ar, but on the pistols it is just a light tap to make it go.  I've even done it by just reaching up with my thumb and pushing.

Fowrard assist is not a problem solver, it's a problem waiting to happen.

If you have a jam, take the time to fix it properly. Don't ram the problem home!!!

On the range, should have taken his time and done it right.  In an attempt to look like a bad ass, he had to settle for dumb ass.  If you got to hit the bolt a half dozen times on any rifle, you've got a bigger problem then carbon fouling, which, I believe, was the only thing the forward assist was meant to solve, not catastrophic $%^# up's.

That and letting you silently chamber a round by working the charging handle slowly then tapping the FA. I never did it, but that was theory we were taught anyway.

how hard can it be to tech someone this?

Tap, rack bang.

there aint no "smack the FA and then pull the charging handle"

Indeed. SPORTS (Slap, Pull, Observe, Release, Tap, Shoot). Live it, learn it, love it. I do not remember being taught to to rack the handle then randomly hit the FA like a monkey on speed.

I'm guessing this guy learned to shoot from the same late night movie.

You see the idea here is to prove how tough you are!

You know, when a hot case pops up in the air, hits you in the eye, then goes down your shirt.  :o  You just grin and say.  "Yeah!  That's how I roll!" ;D

I have been told that there are (minimal) differences between .223 Rem. and 5.56 Nato ammo, resulting in 5.56 Nato rounds possibly not chambering properly in a rifle chambered for .223 Rem. This is apparently the result of different production standards being used for .223 Rem. (Saami specifications) and 5.56 Nato (European specifications). Also, as a result of these differences in specifications 5.56 Nato may result in higher peak pressures.

Could this have been the cause of this failure?

5.56 is a hotter round and can cause a rupture in a .223 chamber.

.223 is safe to fire in a 5.56 chamber, but not the other way around.

If you look closer, the gun is not into battery. The round never fully chambered.

Exit question: name that gun!
