Strike Industries AR .223/5.56 Miller Comp is a muzzle device designed to mitigate recoil similar to the SI JCOMP but in a slimmer package. It features a two-chamber design that is slender enough for a .750" diameter gas block to slide right over it. Since the Miller comp matches the profile of the host barrel, it allows users to mount or remove the gas block without taking out the muzzle device. Easily reconfigure your rifle at any time by swapping, adjusting, or servicing the barrel nut, gas block, gas tube, and handguard without worry. Pair the Miller comp with a 14.5-inch barrel by pinning and welding for a minimum legal rifle length of 16 inches. The Strike Industries Miller Comp offers a slim, lightweight option without compromising performance.

Nice comp.

Love the small size and design. A First rate muzzle device.

Perfect for a pin and weld build

Love these comp/flashhiders. Built two rifles with 13.9" barrels and pinned and welded these on them . Total OAL 16+". Best of all, I can remove my gas block and barrel nut in the future for any upgrades.
