Reloads? Seen that with incorrectly reloaded ammo. Either too hot, or a squib went first then a round fired after.

 

Yep, im going with a squib load.

 

Re: Concealed Carry bills problem

Yeah, I'd like to know what ammo he was shooting.

.223 loaded with pistol powder?

 

Said he bought the gun and ammo from same shop.

 

It even blowed the magazine apart!

 

Contact fiochi to see if they offer any warranties which may cover any firearm damage resulting from using their ammo.

 

First thought was squib followed by a regular round.

Do the lower and upper match?
Lower says 5.56, is the fiocchi .223 or 5.56? Not sure 5.56 would pop a .223 upper like that but just a thought.

In any case glad everyone is well enough to take pics and chat.

Blame Tapatalk

 

Yea, thankful nobody was hurt. I was shooting on the bench next to the guy when it happened. Not sure if the upper and lower matched, but probably didn't.

 

Id be interested to hear what Fiocchi has to say.

 

I could see the buck being passed back and forth as to who/what is responsible. He may end up eating the repair cost himself on the end. I do know that I would have had to change my shorts afterward if I had been the one that pulled the trigger.

You're probably right. What did that sound like?

 

I doubt you could get the ammo compaby to admit to anything.

On a side note, since no one was hurt, that's what he gets for putting UTG crap on an Armalite... kidding of course... kinda...

 

If he just bought it he probably also payed stupid money for it too. That just sucks.

 

Looking at the pics, looks like he got lucky and didn't destroy the lower at least...

 

I would contact Armalite. They will probably want the rifle and the ammo so they can determine the cause. They will probably replace the rifle and recoup costs from Fiocchi if they find that is what was caused the malfunction. In ARs, since they can't fire out of battery, by design, the ammo is usually the culprit.

 

Could have been an out of battery explosion. That's my best guess without examining it.

 

Trust me they can fire out of battery, I know first hand about that one and a few here have seen the aftermath of my explosion.

It would be nice to know if the barrel was marked 5.56 or .223.

I would bet on a squib as well, you really cannot put that much powder into a 223 case. They are proofed at 78,000 psi. A normally loaded 5.56 is almost a full case of powder and is about 58000psi, at most you might get 10 to 20% over in a 556 case, so that would get you to the proof level pressure range, no way that would do that much damage unless there were other contributing factors.

Also I would right the lower off as well, no way I would ever shoot anything off of it, when mine exploded it slightly ballooned my mag well and the anodizing was cracked, I would bet it did the same thing to that one.

Also I do not think Fiocchi makes 5.56, I think they only make 223 ammo so I doubt it was just the ammo, again leaning towards a squib, but even that is unlikely with modern manufacturing techniques.

Just to be clear there is no difference in a 223 upper or lower receiver and a 556 upper or lower receiver, the actual receivers are identical. The only difference in 223 and 556 is the barrel and the chamber. Even the bolt is the same between the two. Now there are various levels of quality such as MPI and proof tested barrels and bolts as well as tolerances on the upper and lower receivers, and usually the milspec have a bit larger tolerances than the better billet stuff.

 

Thanks for the input guys.

 

all i can say is wow

+1 Squib most likely.

 

This is what happens when the projectile is not crimped in the case properly, during firing the loose projectile will back up into the case due to recoil while it is in the magazine. As soon as the round is fired the projectile can't escape the case and you get a severe over pressure issue that sometimes just blows the mag out of the bottom of the gun and hangs everything up and other times it does what you see hear. Me and my friend started reloading at the same time and we both made the same mistake my gun had the mag and contents blown all over the place and the bolt carrier jammed up inside the upper, his ended up as you see in the picture we traced the problem back to this after he blew up a second one we picked up a round this had happened to off of the ground. Be careful reloading be even more careful with you crimps on ar ammo. This is a very easy and dangerous mistake to make.

 

Shortfuze... I'll amend your statement to say that this might happen when the projectile is not crimped in the case properly. The need for a crimp is going to depend on the quality of your brass, choice of bullet and load selection. Running at max/near max loads, poor case neck tension or minimal bullet bearing surface are conditions that may necessitate the need for crimping. While crimping certainly doesn't hurt, it's not an absolute requirement.

My AR is on it's 4th barrel and I've never crimped a single round of reloaded ammo (approaching 14K rounds on the gun). No issues so far.

 

im just reading about minimal bearing suface!

 

I know for a fact that it will cause it because we both did it and upon inspection we found rounds that this had happened to. I have unloaded a mag and found one in it thankfully I didn't shoot it and have to buy more parts or go to the emergency room. Recoil can drive a uncrimped projectile back into the case and this will be the result . No it is not a requirement but it is another level of safety that is worth doing to prevent this. I hope it never happens to you all I am saying is be frickin careful.
