AK brake but with 1/2x28 threads

[rowdyb]

My  RD built AK has 1/2x28 threading for the A2 style flash hider that came on it stock. My gun is in the traditional 7.62 caliber. I want to replace the flash hider with a brake, but I can't seem to find a brake for either .308 or the AK's 7.62 in that thread and pitch.

 

Help. Looking for a brake more so than a comp or other flash hider.

CNC Warrior makes a few muzzle devices styled on standard com bloc models, but with 1/2x28 threads. The specs for their products make things a little ambiguous as to whether or not models available in multiple thread patterns also have multiple bore diameters linked to the thread pattern (i.e., that the 1/2x28 version has a 5.56 diameter, the M14x1 version has a 7.62 diameter, etc.), but it's worth asking them, I suppose. If absolutely all else fails, one of the devices they sell is a 1/2x28 to M14x1 adapter, which would open up the possibilities for more traditional options.

 

I believe that at least some of the brakes manufactured by both APA and Precision Armament have a bunch of models based on mixed-and-matched bore diameters and thread patterns also, so 7.62 bore and 1/2x28 might be options there. Probably others, but those are the only ones that I have semi-recent purchase history with.

Thank you very much! Looks like I'll be paying the price of having a non standard barrel. hahaha.

Can't you use a 1/2-28 thread 9mm brake?

And probably a 300bo one as well, just having trouble finding them in stock.

I might have one in the parts bin in the garage that would work.  Let me check.

I have one of these I'm not using that I'd be happy to get rid of.
