JK ARMAMENT | PRO-KOR 556K 5.56mm Suppressor | 1/2″x28

The JK ARMAMENT PRO-KOR 556K is a 5.56mm suppressor engineered for durability using advanced 3D printed construction from 17-4 stainless steel and Haynes 282. Its optimized internal geometry is designed to deliver efficient gas flow, reduced back pressure, and a low flash signature while providing sound mitigation suitable for sustained use. The unit includes a user-serviceable end cap and ships with an included War Eagle muzzle device, and it is compatible with HUB 1.375 24 mounting systems. This suppressor is presented for use on short-barreled rifles (SBRs) and full-length carbines where robust construction and modular features are priorities.
