The Strike Industries Checkmate Comp (brand part number SI-CM-COMP) is a Black parkerized steel muzzle device built for .223 Rem/5.56 NATO AR-platform rifles. Strike Industries designed the Checkmate as a multifunctional muzzle device with four off-set, serrated, angled prongs rather than a solid brake body, giving it both compensating function and an aggressive, purpose-built look. The top port is set to the right, and the aggressive front profile is built to discourage anyone from crowding the muzzle in close quarters.
