Screwwed up muzzlebreak

nighthawk80 · 07-16-2007, 11:41 AM

Went shooting Saturday. Decided to my newly built Romainian AK with the new muzzle break and buffer. At 50 yards my point of impact was at least 4ft off to the right, yes at least 4 ft!!!. Took the muzzle break off, the POI was correct. I bought the AK-74 muzzle break look alike that is make and threaded for the 47. I wouldn't of thought I would af made that much different. I didn't notice anythink wrong with the break when I installed it??
Might have to send it back??

check the crown on the muzzel.Also are the threads the same on the brake as the muzzel.That is so weird.The brake might have a 28 thread and your barrel a 1-14 thread and it doesn't sit right.bullet might be striking it.check those..

I had the same problem with the AK-74 style break on an AK-47. When I looked real close I noticed that the bullet was hitting the inside bore of the break. My guess is the threads on the AK were a little off. It really didn't matter with the short slant break, but the longer break caused the bullet to very slightly impact to break. As you can image, it really fouled up accuracy. I simply took a drill and made the inside a little bigger to give the bullet more room to get through. Worked fine after that. I really didn't like it though after I got it fixed - it was way to dang loud. I would up going back to the slant break. Actually, I sold that particular AK - it was a WARS-10 POS. Also, be sure your break is US made to keep your stupid parts count legal.

Could the problem be that anAK-74 is 22cal and anAK-47 is 30cal.

SilverRun · 07-16-2007, 09:22 PM

On my break that was not the problem. The break was made for a .30 bullet. Not sure on others.

They muzzle break is a coppy of the AK-74's muzzle break, but made for the AK-47.

I think you might be right. I was looking at it last night and it looks like it might be doing that. I will have to look again when I get back home. Didn't get much time last night, due to my daughter not feeling well.

Take the "muzzle brake" off of the gun and smoke the exit end with some sooty smoke such as from a kerosene lamp. Then reinstall the muzzle brake on the gun and shoot one shot. See if there is contact from the bullet on the brake. For a muzzle brake to be effective it has to be concentric to the bore and no contact can occur. If there is contact that will prove your accuracy problem.

What does that mean? Are you mocking my post? A quote from the movie "Spies Like Us" we mock what we don't understand

YUP!

The birdcage brake I got from sportsmansguide.com worked OK but was too big a diameter for the bayo to fit. poopy! Looks good though.
If it screwed on OK, it should have not caused any problems. If the bullet is hitting it, something aint right. Send it back. That's some tough metal to drill or file. (It's a brake, not a break. Muzzle brakes are irrelevant on semi-autos. They are just for looks.) If it affects accuracy, replace it, or leave it off, or put the slant brake back on.
