So, my AR exploded today…

That slightly bulged case would have been end of shooting that batch for me.

Yup live and learn

We are all jumping on the ammo band wagon but what about the gun??????? What mods have you made? Any upgrades to the trigger? If the gun, gas system and trigger are stock then I agree ammo is the next step. I have never seen detonation like that in smokeless rifle powder case failure or not. That is more like pistol powder in a rifle load detonation.

Well which one? Lol

 

[DeepSouthArmory]

I seriously doubt you'll have any problem with 9mm.

I shot 200 rounds of their 9mm from 2013 last week, no issues. I use them at the range because I don’t reload their “stepped case” brass.

 

[Ric-san]

Not sure if mentioned by anyone yet, but if no one was hurt, I’d buy a lotto ticket.

 

[GeoW]

This company has had problems in the past. Happend to a buddy of mine with their 223. I steer clear of them entirely.

Black Dot ammo on the other hand..... I have shot multiple hundreds (but not thousands) of rounds of 223 and 9mm with no issues.

So, you work for Black Dot?

 

[Jester896]

I passed a Holiday Inn today....but I can't imagine anything with the trigger causing the case to blow out the primer that far, etch the primer pocket, cause the extractor to rip a piece of the case off and separate the case head... that came from over pressure

 

[Hdjake73]

I have a S&W M&P sport that has had thousands of rounds through it (but not tens of thousands)
A friend gave me some Freedom Munitions ammo, and I am fairly certain the case failed.
No one was severely injured, but I’m out a rifle, magazine, and can’t trust the ammo.
What would you do next?

Get a new one lol

 

[FrommerStop]

The first I check is that a 300 black out round was not chambered. But that seems unlikely in this kaboom.
It must have been a series of thing going round. A weak case head, over load and maybe to great a case length. It seems that bolt's locking lugs and recesses of the barrel extension held.
I will make it a point not to purchase that brand of ammo.

What could cause that kaboom would be something similar to range sweepings. During reloading operations when powder magazines get low, they may have loaded smokeless powder dust into that case. That would go off like high explosive and not a fast burn as is normal.

 

[chipster]

buddy of mine lost 2 rifles to bad FM ammo - he put a damage claim in with FM and was able to get some $$ towards repairing his rifles. Yours needs a bit more than the parts he did, but hopefully they comp you something.

 

[Klugey1]

It’s close, but I think I’d rather shoot Tula than Remans…

 

[jotec]

Damn still have a couple 1000 freedom ammo in 223. Some is new. Im going to use it up and start buying something else.

 

[Jdcujo]

So, you work for Black Dot?

I've run black dot and I like their stuff compared to freedom

Have you looked through the barrel for a squib? But I would definitely contact FM and S&W about it.

 

[oneshot]

DON'T know but the case I saw looked like a 762.39 case have seen a couple of these lately the bullet goes out the barrel and case out the back a 39 round will go in to a 556 chamber. Also have seen and have had it happen when fireing had 3 happen when I was pulling the trigger. The problem turn out to be the bolt was not locked up fully . Have find two main things one is with reloads is the case shoulder is pushed back a couple of ths. when the bullet is crimped in this is caused by two main things case neck is to long, or the case is crimped to much. there a couple of factors also The other thing is I have seen is with the Wil. camber have run a 556. chamber reamer in helped this out. This just for starters I can't type ever thing Ihave seen . Just my 50 cent jj

No fear

 

[Lucky Number 700]

Do you normally run your gun dry? I don't see a spec of lube. What was the string of fire before the massive failure? If the gun was hot, there could of been a cook-off before the bolt locked into battery. Just another angle to think about.

 

[ChrisC]

More than likely, the hammer dropped while the bolt is not fully in battery i.e did not chamber the round completely. Test it with your UNLOADED AR, retract the bolt enough and pull the trigger. Its hard to double charge a .223 with the proper powder.

I second this. I ain't as smart as most of you fellers but everything I see screams over pressure.
