original quote "Ive a century arms sportier. #04809. I was shooting with my cousin and when he CENSOREDGI it this is what happened. He is at the hospital now with minor cuts and powder burns to his eye. Does anyone know if there any recalls or has this happened to anyone else. Called century arms but they aren't open now so left a message."


she uploaded some pictures of the ammo she used, and its pretty clear its monarch factory ammo.





they bought this gun 6 months ago, and it came with 200 rounds in big ziplock bags, said they were on stripper clips and they all seem to be ppu marked brass.



anyways, the guy has minor cuts and his eyes have some burns but nothing that will be permanent of course.

What do you think happened?

How it happened: They shot it a bunch 5 months ago, stored it and never cleaned it. Took it out to shoot today and the very first shot blew up like that. Would contacting Century arms be worth it? is it their fault or how can they determine what caused this. thank you in advanced! sorry this might not be the right place

NO maintenance on the weapon, sure ain't Century Arms fault!
Was the bore even checked for obstructions before firing?
Why wasn't the shooter even wearing safety glasses?
Sounds like a bunch of stupid came together and the 'shooter' is damn lucky to still have his eyes!

Not sure where the CETME came from but that appears like a Galil AR sporter. Looks like a case failure at a minimum or and out of battery firing. You need the remaining case and to look at the bolt & lugs closely. Been there and done that.

Shooting it without cleaning does not usually cause a gun to blow up.

Barrel obstruction causes the entire barrel to split, much more violently than this.

From the way the mag is blown out, I would guess it is an out of battery ignition, or a hot round.

I would guess this is not shooter error, but is ammo or gun related. It is a reminder though that safety glasses are a good idea always.

I figured it out! That CETME is a galil.

Now, all kidding aside; We need a pic of the failed cartridge case. I'm guessing out of battery discharge or other head failure unless the barrel is also wrecked.

Also, bagged ammo always makes it suspect in my opinion. Need more info.

Very nice pics of the issue. That mag looks like a busted water balloon. I will be watching this thread very carefully.

Dang, I almost bought some of that ammo at the gun show and at a LGS a few days before. It was a bit expensive so I passed. If it turns out to be ammo related, I can thnk my guardian angels...AGAIN.

bolt is stuck so they can not open it to give a better view. they think the case is still stuck in the gun but they can not tell since the bolt is stuck

Just cause.....CAREFULLY run a cleaning rod from the muzzle and mark where it stops.
Remove c'rod and place that mark on the outside to see how far the rod entered the bore.
You want to remove ANY AND ALL CHANCE that there could be a live round in the chamber.
Good luck and please be careful,

I would aim it in a safe direction and remove the top cover and use a block of wood and give the bolt carrier a rap to unlock it. You have to clear it before moving it around or off the firing line. It appears slightly unlocked with the bolt carrier slightly to the rear. The top cover should be easy to remove and you can better access the carrier.

While it pays to be careful, I'd bet there is no live round in there. The reason the mag is bulged is that an overpressure event in the chamber blew the mag apart, which means the bolt did not cycle to pick up a new round, as those rounds were very quickly blown through the floor plate.

My uneducated guess is that it is either due to bad reloads or bad workmanship by the semi-trained monkeys that put CAI's guns together.

I'm casting a vote for bad ammo as well! Ammo in baggies leads me to believe it was reloaded? Possibly over charged with powder? Primer not fully seated? Bad circumstance all round! Tell him to buy eye protection and to thank God for the continued use of his eyes! It so easily could have been so much worse...

That is a Prvi Partizan case. I have fired a lot of ammunition with the PPU headstamp without any issues. Can you post a close up of the case mouth, so we can see the crimp area? I would question if the rounds were reloads.

I had some pistol ammunition that was loaded by a commercial reloader do the same thing in my pistol. The magazine was blown out of the bottom of the pistol. When I pulled several bullets, the powder appeared to be of three different kinds. I have no way of positively identifying what brand of powder it was, but there was definitely a difference in appearance.

If the cases were not fully resized when reloaded, it is possible that the rifle fired out of full battery, which would cause what we are seeing in the picture. If you fire factory ammunition out of a rifle that has cosmoline built up in the leading area of the chamber that would cause this issue as well. If a bullet is not properly crimped, it can set back in the case under recoil whle the cartridge is still in the magazine, which would cause excess chamber pressure when fired.

Google Century Arms headspace and read what some other folks have to say. Excessive headspace is a dangerous condition.

Please turn the rifle upside down and take a photograph of the inside of the magazine well. Pictures of the ammunition case mouth, especially the crimp area, would be helpful as well.

If it is an ammunition related failure, it is unlikely CAI will accept any responsibility.

The fact that the bolt is stuck closed would give me great cause for concern- obviously strange things were happening, but if it was blown open without picking up a round what is it jamming on? I would be very very careful at this point. And if it's the defective round still in there, they'll want to get it out without further damage, in order to see what went wrong with it.

I do occasionally see 5.56 brass at my range that split wide open and was left lying on the ground- always wondered what it was like shooting it.
And I hope they'll get rid of the remaining rounds from the baggie in a way that they can't cause further damage. I'd get an experienced reloader to pull the bullets and do some home forensics on them.

well that looks like the PPU 55 grainers i have laying around
Including the mouth that has a nick in it. all my .223 Partizan, which i bought in 2 500 rds boxes straight from the importer have those..primer has the same colour, so that "look" ok as well.

It's not really accurate ammo, 2 moa at best, there's always a flyer or 2 in each 5 rd group i suppose the case mouth having nicks in them can't help with that.. but i have not had any problems with it in my AR and i've shot at least 500 of em so far.

This is a classic out of battery event. Next comes the question as to what caused the event.

There are only two places to look; the ammo or the gun.

Without regurgitating the laundry list of common problems in each of the two places, it is instructive to note the comments in the original post. There are more and more people whose very first gun is a self-loading, magazine-fed, high-powered rifle. These people have most likely never been in the military. They have never taken a hunter safety class. They did not earn the Boy Scout air rifle badge.

When provided the opportunity, it is a moral imperative for those who understand firearms safety to impart their knowledge and experience on these new owners. No, you can't fix stupid and Darwin was right. But if you pass on a chance to tell a novice shooter what you know, then you are simply not doing the right thing.

Since the early 1900's, there have been no new ways invented to blow up your gun, or yourself. If we could avoid the mistakes previously made by others, then we are going to be safe. But if you don't know the history, then you will repeat it. And may end up at the eye doctor's office.

In my opinion.

Get the rifle disassembled and see whats in the chamber. Also take pictures of the bolt face. Century isn't exactly known for quality so they could be at fault. Nevertheless... It is always important to give your guns a once over before you go shoot to check for proper lubrication, barrel obstructions, etc. Hopefully your friend is not too hurt.

ETA: I am also weary of 'factory' ammo being sold in plastic baggies. I hand load most of my rounds, but stuff like .303, 8MM, and 7.62X54r I always buy. Did you buy the gun from a store or private seller?

Bolt is probably stuck forward because the face is deformed from an overpressure round in the chamber or there is debris still stuck in there. Or maybe a separated case and it somehow chambered and fired the next round.

Ammo in plastic baggies at a gun show? If that's true then his friend just learned why the rest of us cringe when we hear that.
