My bud and I were at angeles today, I had my 03 springfield and my savage 110 blaster and he had his cali bushmaster carbon 15 and his HS precision .308. My bud only buys the best available when it comes to all things firearms, that said, he bought the busmaster before learning about calguns and OLL's. Today he was shooting away without a care in the world , I was sitting on his right and had just gotten up to clean my savage when I hear "holy sh&t, dude, check this out!", I turn around and everyone is staring at my bud who is standing over his now 50 plus piece AR15!. The upper had just exploded and took out the lower, the scope broke off and hit the deck, his magazine had exploded downward and destroyed 5 or so rounds, even the handguard looked puffy!. Then I see a guy 4 benches down walk over and lift his shirt to reveal a nice bruise where part of the receiver hit him (scared the little guy pretty good, he thought he got shot). There were 3 holes in the screen (brass deflector) where the receiver blew apart. I have never seen a rifle disassemble itself like this, it was really sad. Any of us would have loved the rifle, it had all the tasty bits on it, not cooter but classy. If I had not gotten up to clean my rifle, I would probably be sitting in a waiting room with a bloody rag on my left ear telling the story!. I hope bushmaster stands by their products.
OK Ted, here goes:

Man that sucks, but I gotta do it.

[6079Winston]

I guess we can't complain too much about the range master being a nazi for safety glasses anymore. Any idea what ammo was being used?

[Josh3239]

Dam, that makes me scared to take mine out. Especially because I just changed the gas block. My Carbon 15 has never malfunctioned and I am 100% sure I put everything together correctly and now you got me worrying.

Had he done anything to it? What kind of ammo was he using?

[ohsmily]

No, this thread isn't worthless without pics, BUT, it is worthless without some more information about the ammunition being fired (reloads, commercial, etc) and whether the gun has ever been modified or messed with (trigger assembly, etc); whether it was being bumpfired or operated in some other negligent manner (maybe fired out of battery).

Federal American Eagle in the red boxes.

[daskraut]

yea, what he said, federal am eagle. It was being bench fired and the bolt assembly and upper are mechanically stock, no trick parts, just a slick hand guard. The bolt was awesome and just inspected by a pro. Sorry about the lack of pics, my bud took some shots at the range at my insistence,and will submit them to bushmaster first. Sorry. I want to make sure they don't feel slammed in public as were hoping they make good on their product.

[Fjold]

Good info daskraut.

[Prc329]

Glad to hear everyone is o.k. Your buddy is fine correct?

[thmpr]

I hope no one got hurt. FE ammo are not known for hot loads. XM193, yes. Shot several hundred rounds through my BM Carbon-15 with no issues. Do you know how many rounds he fired prior to the kaboom?

[CSACANNONEER]

Don't fire anymore ammo from that lot until the ammo itself is ruled out. Contact the manufacturer and find out if there have been any other problems that might have been caused by this ammo. He might have got either a squib or a double charged round!

If he had just cleaned his barrel, he might have left a patch in it by mistake.

[Black Majik]

Holy crap! Glad you guys are alright. Were you guys on the rifle side of the range? We had a few people shooting OLL ARs on the pistol side today, but I didn't hear anything about a AR kB'ing.

Glad to hear you guys are alright.

[paco ramirez]

That really sucks. It could have had something to do with the Cam Pin.

[Solidsnake87]

I had a C-15. I noticed that this rifle, like any other new AR, will not fully chamber a round if the chargine handle is slowly allowed forward to chamber a round. (I've only seen this slow loading technique on new AR users). Could he have pulled the tigger on a round not locked in the chamber?

[ghost]

its good to hear no one was seriously injured,the rifle is replaceable at worst.

[metalhead357]

Awaiting pics and more info 'fore comentting out my oraface.

The firing pin can not protrude through the boltface unless the bolt is locked in place.
Suppose you have a cartridge in the chamber and the bolt is 50% locked when the carrier stops.
Pull the trigger and the hammer hits the carrier, causing it to move forward.
If you have an un-shrouded carrier, the hammer hits the firing pin, which drives the carrier closed.

In either case, the bolt is fully locked BEFORE the firing pin can hit the primer.

There are no out-of-battery KB's on locked-breech AR's caused by direct firing pin hits to the primer.

[CRTguns]

I've seen the old glocks get an out of battery discharge due to a primer that is a little proud. The sharp edge that strips the round out can crush the edge of the primer in, and buckle the primer cup, firing the casing. If this AR was at battery, no KB would have taken place. The steel would have contained everything. If the plastic went KB, one must assume that the ammo was defective- ie, a protruding primer.

Like AR15 barrels says- the bolt has a slam fire disconnect and a block to prevent the hammer form striking the firing pin until the bolt is fully at battery-

the fact is, that out of full lockup, the bolt is TOO LONG for the FP to protrude into the shall casing.

[C.G.]

If you had any carbon fiber penetration, go to a doctor and have them remove as much as they can.

Lately, there has been a reevaluation of carbon fiber in the bloodstrem. Carbon fibre in many forms acts like a knife.

[Addax]

Geeeeez, I hope your friend is ok...

Please keep us posted/updated with pics as soon as you can.

[Nefarious]

Definately, could have been worse. Really interesed to find out the cause - if thats possible - of the explosion.

[Fjold]

Did the failure occur in the middle of a magazine or on the first or last shot in the magazine?

[daskraut]

My bud had one major sinus headache from the gas released into his face, he said on the way home that it felt like someone punched him in the face, but at least he didn't get fragged!. Someone said something about leaving something in the barrel or not letting the bolt drive home properly, this was maybe the fifth round fired in the clip. Total thru the rifle?, maybe 2000 rounds. Makes me want to inspect my plastic Kel-tek SU-16 after every magazine. I love "woven" carbon fibre, but hate that mixed paste stuff!, I don't trust it in aviation and now firearms (think airbus rudder in windshear conditions)

[mxpatriot51]

What chamber does that C-15 have? .223 Rem, 5.56, or .223 Wylde?

If 5.56 was being shot in .223 REM, that could have been the cause.

[Prc329]

AE Red box is 223.

[SFV_Dealer]

Wow, glad everyone was fine. Guess they design these rifles with some sort of catastrophic failures in mind.

That's why when we sell a BM Carbon 15 lower, we always tell our customers not to get the carbon upper but rather get a standard aluminum one because I have heard of other BM carbons that have had uppers blow.

If 5.56 was being shot in .223 REM, that could have been the cause.

Highly doubtful. The difference in the loads between .223rem and 5.56mm is miniscule to not existent. The main difference is in the chamber specs. 5.56mm has slightly looser chamber specs to allow for ammo that may be dirty or slightly out of spec diameter/length wise. A "military" rifle should eat ammo no matter what.

This event and others like it are perfect examples of why CA gun laws are unsafe and place us in danger by forcing us to comply. The M-16/AR-15 weapon system is specifically designed to blow the magazine, gases, "explosion" and anything else out of the bottom of the mag well in the event of a catastrophic failure. In many cases after such a failure the upper receiver is perfectly fine (less perhaps the bolt & extractor) and the magazine is the only thing that needs to be replaced. With a fixed magazine rifle, if you encounter a catastrophic failure the rifle cannot perform as designed and you have events like this.

The only thing worse than a gun made out of aluminum is a gun made out of plastic.

And don't forget those those plastic bombers and fighter jets.

What are they thinking?

I would think that is part of their plan. Get our own weapons to blow us up and then they don't have to worry about us tying up their phones and fax machines anymore and can get on with more useful things like voting themselves raises and passing the cost on to the tax payers.

Ok, here's my plan for instant wealth. Bushmaster has deep pockets loaded with cash. We go to the range and shoot our C-15's until they explode into smithereens. Take photos of our bloodied hands and faces and claim all kinds of permanent injuries in court. Settle out of court for say 1.2 million or so. Easy huh?

Thanks BM!

not quite, Glocks are baller, and state of the art. THE BEST HANDGUN YOU CAN GET FOR THE MONEY!!!

[bwiese]

Did we just get an influx of teenyboppers on Calguns?

"Glocks are baller"?

And dissing WWI handguns like the 1911, which has helped interrupt the breathing patterns of countless enemies of America?

Geez. Barely-literate posts really do a lot to promote our standing as competent, skillful folks.
