AK 74 bullet hitting brake?

[Fattman]

So I bought this AK off NES a few months back and finally put a scope on it and brought it to the range. After a couple shots at 100 yards I could not see my shots anywhere so I chalked it up that I needed a 5.45 boresight so I packed it and finished sighting in my other new glass. Just got to cleaning it and noticed something strange on the brake.

It looks like the bullet hit the brake which would explain why I was not seeing impact. Pretty scary stuff if that in fact is what happened here. What does the braintrust here think?

Ideas on how to fix it?

It's pinned so if I have to replace it, that royally sucks

Im not metal worker, but perhaps the brake could be reamed out a few sizes above the diameter of the 5.45 bore. It should be already, but perhaps it's miscut originally. shouldn't have to take it off the barrel if it's pinned as long as it's only a brake issue, and not a problem with the barrel. good luck. I'd call one of the proven and competent gunsmiths talked about on the forum, one closer to you for ease obviously, and see what they can do for you. can't imagine it'd be that expensive theyre not reaming a chamber…


glad you're safe and didn't get hurt. the most important part right there.

Try putting a brass rod in the bore that is as close to actual diameter. If it touched the brake bring it to a shop and have it reamed out a little bit. You could do it yourself but that would not help the accuracy of the rifle. Did you only shoot at 100?

Who's the manufacturer?

 

[Fattman]

It is a SAR 2 made by S.N. RomArm S.A. all matching part numbers.

Yes just 100

Your threads are probably not cut perfectly straight on your barrel (as is very common with these Romarms rifles), and this gun was probably shipped with a slant brake. The addition of a much larger muzzle device not sitting straight on the barrel has lead to these 'end strikes". You could also have pre-existing serious damage to the crown under the brake, which would ultimately have the same effect. Unfortunately, short of cutting the barrel down, moving the front sight back, re-crowning, and re-threading the barrel, there is not much that can be done here. My advice is to switch back to a slant brake or muzzle "nub" device, so that you can still use this firearm safely. End strikes that severe will eventually cause catastrophic damage to the end of your barrel, please be careful.

On SAR II's the AK74 style muzzle break was an option. The rifles came in from Romania and Century Arms International put them on via welding them to the barrel.

The barrel is romanian, if it is indeed an unmolested version. This will not have a shit CAI barrel on it. The only way the crown is ****ed is by the end user (cleaning it with a steel rod like a dumbass, doing other dumb shit, etc). So if the crown is causing this issue, someone ****ed with the gun and it now needs work.

If you happened to load .223 into this rifle, you'll also get similar results like this. If indeed you were dumb enough to do this, the mag will load it, and the bolt will chamber and fire the round. Double check your ammo and make sure you didn't do something dumb like this.

Get an image of that crown. And get an idea of what the bore looks like in that barrel. If someone was cleaning it improperly you'll find out real quick with a visual inspection.

A few other questions:

1. Was this rifle unfired when you got it?
2. What does the muzzle break look like?

This will help us identify what could have possibly happened here.

also- I sympathize with you heavily. I've helped people with poor purchases before when it comes to AKs, and it's ugly. People pass around turd AKMs like hot potatoes and "try to screw the next guy" because "it's just an AK anyways." Lots of shitheads like that in MA.

I had a Saiga (7.62x39) once that was sighted in and shooting well. I put a '74 style brake on it and I was suddenly hitting the target stand, 2' low and 1' to the left. My brake had nicks like yours. I reamed it out with a dremel and it was fine.

With yours being an actual '74, I'm not sure if you can go back to a slant brake. If it were me, I'd take it to G&N and get it sorted out.
