AK-74 style muzzle break on my WASR 10

[Big_Willy]

I purchased an AK-74 style muzzle break / compensator, 14X1mm LHT.
It is supposed to be vertical in position for top side compensation gas expulsion.

I'm putting this on my WASR-10 which has the proper threads to fit this style.
When I tighten it down to the last possible turn where the index key (the small little spring loaded catch thingy) locks it
in place, it is in perfect vertical position. Although a small amount of thread remains (about 1/32" or so) and there is a wobble which seems
(UMMMMMMM!)..... A little dangerous.

BOOM!!!

When I depress the Index key and screw it all the way down, it fits very nicely but the muzzle break is not in a vertical position.
Could I add a thin flat washer to correct this problem?

I tried to fabricate a small nylon washer for a test fit. After Dremeling and sanding it soon made a perfect fit where the muzzle break did not wobble or move at all and it was in line vertically and as well with the bore.

The only problem is its nylon and barrels get HOT!!

What do you think?
Fabricate a metal washer to fit?
Will it be safe? :banghead:

Think of YOUR SELF testing it for the first time.. HE HE

All help is greatly appreciated

Thanks

I have installed

various compensators to AK's, and have had to file down the compensator to fit the barrels's. The "peel" washers available are too small for the AK threads.
It take's a little time, but is worth it

No, its 100% perfectly normal for brakes to wobble, and not go on all the way. Every AK I have with a threaded muzzle or FSB has wobble to some degree.

As long as the opening in the brake doesnt move into the path of the bullet nothing can go wrong. With military brakes, this isnt a problem. With an unknown brake, who knows. Without seeing it I cant say if the threads are tight enough, or if the opening is large enough. If the opening is significantly larger than 7.62, and there isnt excessive wobble it should be ok.

That would be muzzle brake (as in "slow down"), not break (as in "broken).

Thanks for catching that

Thanks for the correction on my Brake vs. Break ERROR. That one slipped out on me. I also find fun in catching others errors.When you Google either spelling you have tons of returns for both. I'm confused.

We'll its been shot now and its all messed up. The bullets were glancing off the inside (lower right) of the AK74 Brake/Break, thus waisting a ton of ammo when sighting it in. Once I noticed the problem I had already zeroed my gun in, ONLY ABOUT 3' HIGH AND 3' LEFT. I think I'll try to find a slant brake, YEAH the one that is made for my gun. Then after I took that Richard head of a brake off I had to start over and I found that my scope was not tight enough on the rail..."SON OF A B" What a waist of a day at the range.
I did end up getting some decent groups at 100 yards with the last two mags of the day.

7.62x39mm Ammo is starting to show up all over again. I found some for 2.49 a box of 20 near home.

Later yall.........

"The bullets were glancing off"??

That isn't right. I have same style of brake, and it wobbles; maybe a mm or so at the outer end.
Certainly not enough that it could get hit!

After threading it on with only 1/32 left, you'd not expect much wobble at all. Something doesnt appear sized correctly....

Just one point: the WASR-10 is in caliber 7.62x39mm. The AK-74 is in caliber 5.45x39mm. I do most sincerely hope that your "AK-74 style" muzzle brake is in the right caliber for your rifle...

 

[blackdragon]

The threads threads on my sar2 (5.45) are huge for the caliber -- the romanians apparently do not thread the barrel, but rather thread an extention from the front sight block.

I've never compared sizes, but they do look close. Maybe close enough to cause confusion?
That could be nasty....good call Preacherman

To eliminate wobble, once you're sure of size that is, go ahead and silver solder it on. Silver solder is removeable if you decide you want it off later.

 

[MudPuppy]

They definitely make AK-74 style brakes for the 7.62x39 rifles--the link provided specifically mentions 7.62...it also mentions that you should check the bullet clearance for that brake.

I've seen a lot of '74 style brakes advertised for 7.62, but that site is the first I've seen with the with that particular warning.

Welcome to the club. The brake that I had fitted to my WASR had pretty much the same problem, with the bullets hitting the bottom of the brake prior to exiting. This caused the bullets to keyhole and fly high. I went back to the old slant brake.

Good Shooting

I got an AK-74-style brake too, from Classic, for my GP-WASR 10.

http://www.classicarms.us/htm/specials.htm

It's an interesting 2-part deal. Anyone else got this one?

<snip>FROM A MFG CALLED BLUE RIDGE PRECISION...THE COMP IS DESIGNED IN 2 PIECES. THE BASE IS INSIDE TREADED WITH A 14/1 LEFT HAND METRIC THREAD , THIS IS THE ORIGINAL AK THREAD PATTERN. BASICALLY, YOU SCREW THE BASE ONTO THE WEAPON AND THE COMP ONTO THE BASE. THIS GIVES THE COMP A TRUE EXPANSION CHAMBER IN THE CENTER AND ALLOWS THE PORTS TO WORK TO THE MAX...<snip>

Haven't shot with it yet- it doesn't have the little cutout in the base for the rifle's detent to catch in and keep it from unscrewing... I'm going to make one on it.

Seems like it'll work great, but I'd like to hear, good or bad, from anybody else who got one.... Have seen Blue Ridge Precision in old threads.

If you can't find a peel washer for that muzzle BRAKE...

Find the gasket washer from a spark plug, it's 14mm, too. A little cold blue, and you're all set. That's what I did for the slant brake on my SAR-1.

mines welded on to the front site, no woble here.
