What size muzzle brake do I get for 6.8spc? I have a spare dynacomp for my 5.56 ar15, but aren't the threads different for 5.56 and 7.62?

Do I just get a 7.62 muzzle brake for 6.8spc?

Yes, 7.62 muzzle devices fit 6.8 barrels, provided the threads are the correct pitch. Usually that is 5/8x24, but some companies have used different threads on 6.8 barrels.

It is most likely 5/8"x24. If so, brakes made for 6.8 or 7.62/.308 will work.

I just bought a Barrett M468 brake for my Grendel build. It looks like a two chamber but it is really just one chamber with two ports on each side. I bought it because it was much more compact than most .308 brakes. In fact I was shocked at how small it is when I received it. Same size as an A2 flash hider. It should work perfectly for what I want.

no expert here, but do a search on yahoo/google. Seems to me that stag uses a different thread pattern, but I don't know for sure what the thread is.

Lucky: As you may know, the 6.8 does not have a heavy recoil impulse. Due to the high cost of brass, the 6.8 is not often used in 3-gun competition. Therefore, most 6.8 shooters either opt for a quality flash hider, or they go for a "target crown" on their barrel. For hunting, target shooting and military/police applications, a muzzle brake creates unwanted blast, while flash suppression is useful in any low light situation. IMO, the ideal flash hider is the Surefire suppressor adapter made specifically for the 6.8 SPC cartridge. - CW
