Genuine Strike Industries JCOMPS. Brand new. Crush Washer included, but no factory box.
The Strike Industries King-Comp features large dual chamber design, which was engineered to reduce felt recoil and help reduce the side concussion with the specifically angled gas ports. To top it off, the K-Comp features 4 serrated prongs to provide some flash suppression. The K-Comp is a great alternative if you're looking for a cross between a compensator and a muzzle brake or effective "combo" muzzle device.
