Kaw Valley Precision Magnum Linear Comp 5.56 1/2-28 3.25"

A linear comp does not fight recoil the way a brake does. It collects muzzle gas and pushes it straight downrange, which drops the concussion and noise coming back at the shooter and at whoever is standing on the next lane. On a short barrel AR that difference is obvious the first time you touch one off indoors.

Kaw Valley's Magnum version runs 3.25 inches of carbon steel with a QPQ black nitride finish, bored for 5.56 and threaded 1/2-28. Hex flats on the body let you get a wrench on it even when part of the comp sits under a handguard. There is no timing to fuss with, so a crush washer is not needed — thread it on and tighten.
