The JK Armament War Eagle Compensator/Flash Hider in 9mm (brand part no. JK-MD-HDCF928) is a triple-use muzzle device: a compensator, a flash hider and a quick-attach mount for JK suppressors. This 9mm version threads onto a 1/2×28 muzzle. Its symmetrical design means there is no need to time it during installation, and JK Armament recommends torquing it to 35 ft-lbs. JK machines it from heat-treated 17-4 stainless steel with a black nitrided coating. It also acts as an initial blast baffle inside a JK Quick Attach Taper Mount suppressor, taking some of the abuse otherwise aimed at the first baffle.
