Well-made and affordable, straightforward a2 comp - CMMG, Inc A2 Compensator

No need to wax poetic about this - it's a straightforward A2 comp that will work with 9mm and 1/2-36 threads. I'm essentially using it as a thread protector on a 8.3" BA barrel and just needed something stubby to protrude enough beyond the short Aero guard. I've also used some different setups with the same barrel and arm (blowback 9mm AR) and frankly I don't think there's enough gas for any of the various muzzle devices available to make any noticeable difference in recoil or bounce. This is a quality A2 with a proper finish and it's not covered by machining marks like other cheapies on the market.
