Ok, I am looking for muzzle brakes, compensators or even flash hiders for these calibers on an AR barrel. I believe the 7.62 can be standard threads, but the 6.8 needs to be 5/8x24 threads. The cheapest I have found for the 6.8 is an $80 comp. Are there any cheaper out there?

I like and use the FSC30 (http://www.primaryweapons.com/STORE/PC/viewPrd.asp?idproduct=37&idcategory=6)

The 7.62x39 if you using a Colt barrel is the same threads as a 9MM Colt
1/2 - 36 iirc? I found a guy who had a custom AK47 brake done in the correct threading, just have to look around and get lucky.

Most standard .308 Flash Hiders/Brakes are 5/8-24 and the hole is large enough for 6.8.

Armalite, YHM etc. make .308 brakes.

I found it was kind of a pain finding an AR threaded AK brake for the 7.62X39. I bought a JTAC from Power Custom for my 7.62X39 upper. Uses standard AR 5.56 thread (1/2X28) and works very well. About $50.00.
