AR 556 muzzle brake problems

Today I talked my husband into buying me a AR 556 tan and black. Great looking gun. Couldn't wait to get home and shoot it. We loaded the clip with American Eagle XM193 5.56 x 45mm 55 grain FMJ bullets. The gun came with a muzzle brake which was already installed. We checked the gun out and everything look okay to go with firing it. My husband first shot 5 shots out of it. Everything went great. He handed me the gun I shot it ONE time and the muzzle brake flew off!!! We looked for 20 minutes trying to find it. Found it..... and called the store where we bought it from. We broke the gun down and looked through the barrel to make sure there was nothing in it. We put the muzzle brake back on and made sure it was clear and straight. My husband shot it again and the muzzle brake blew off again!!!!!! We were lucky and found it again!

SOOOOOOOOO.....any suggestions......we are taking the gun back to the store and they are going to call Ruger obviously but I was wondering if anyone else was having this issue?

Could be that a crush or lock washer was not installed at the factory. It fits between the brake and the muzzle and might need some muscle or torque wrench to get it properly attached.

my mistake

It is not a Muzzle Brake it is a Flash Suppressor. The lock washer was on there...however after it blew off the second time we lost it.

I would try a new crush washer. If it's tightened properly, it should stay on.

Welcome, and congrats on your new Ruger! Put a new crush washer on it, snug up the flash hider, and it will be good to go.

I just bought a combination flash suppressor/muzzle brake for mine and it's got a locking/jam nut. Thanks for that info.

Went to the range today to shoot my brand new out of the box Ruger AR556....First couple of rounds went off without a hitch....somewhere between the 5th and 10th rounds, the Muzzle Flash Hider blew off the barrel....found it about 25 yards down range....attempted to re-attache and the threads of the barrel are stripped....went back to Cabela's and all they could do was ship it back to Ruger.....very disappointed it what was an obvious lack of quality control from the factory to ensure the Flash Hider was on securely, although, its feasible it could have come loose in shipping. Probably going to need a barrel swap out with only 10 rounds down range. I am concerned the Ruger won't want to replace this at there expense.....any experience with this happening? Will Ruger try to charge me for a new barrel? Thanks

If the muzzle threads aren't damaged, just get a crush washer and tighten it up good. Some muzzle devices have to be oriented to the barrel.

Muzzle threads are stripped, being returned to Ruger, only 10 rounds out of the barrel. Blew 25 yards down range....I hope Ruger will cover it.....brand new rifle.

I read through the comments and came to this conclusion based on what the op stated. If the muzzle brake or flashider was blown off the barrel, either the barrels or muzzle devices threads were stripped on installation, or not correct when machined.
Or a better theory is that the bullet struck the muzzle device. I have wrenched on many ar series rifles. I have never seen this happen. When you install the muzzle device, I use antisieze, put on the crushwasher, and tighten it down until its timed correctly. Then im done. They have never worked loose, and I have never seen one come off. Another possible cause could be that the barrel and muzzle device are not aligned, which could cause a bullet to strike the muzzle device. I have seen that with a supressor that wasn't aligned corrextly. The bullet struck the baffles and grenaded the internals. Very expensive mistake. I do not feel the gas pressure can rip the device of the barrel, if so what other damage would that gas pressure do to the rifles other parts.

If they are properly installed they will not loosen in shipping, or anything else. If you fired the rifle at a full auto rate for a period of time, it could possibly loosen, which it would begin to unthread, then eventually it would be struck by a bullet, or fall off. But on a semi thats not the case. I feel it was some defect on rugers part, and they should make it right. I would be interested to see their reply.

Glad I could contribute. I also hope that everything gets corrected.

You know I was talking about what it would take to loosen a muzzle device. The combination of heat, and recoil impulse or vibration. Here is a video that the muzzle device worked loose during a test of how much the stoner rifle can stand. Check this video out, it shows towards the end that the muzzle device removed itself. This shows some of the possible conditions it would take to work one loose. Enjoy.
