The Blackout Defense KeyMo Hybrid muzzle brake in 1/2×28 with the H900 finish combines forward-venting jet ports with a closed-prong flash hider, and it carries a Dead Air KeyMo suppressor mount. Four jet ports are drilled at 51 degrees to send gas forward and away from the shooter, which reduces muzzle rise and softens recoil. The ports are recessed with a flat face to cut carbon buildup and make the device easier to separate from a suppressor. It is machined from 17-4 stainless steel heat treated to H900, which gives a deep gold to bronze look.
