JK Armament PRO-KOR 556K Suppressor 1.375×24 HUB, FDE
3 in stock
Description
The JK Armament PRO-KOR 556K is a 5.56mm suppressor built as a single printed structure rather than a welded tube and baffle stack. Its body is produced through metal additive manufacturing in 17-4 stainless steel and Haynes 282, a nickel superalloy chosen for how it holds up to the heat and cyclic pressure of short-barreled rifles and sustained strings. Internal geometry is shaped to move gas efficiently, which keeps back pressure and blowback in check on gas-operated hosts while cutting flash at the muzzle.
Bore rating covers 5.56 NATO and 223 Remington, so it runs across the usual AR-pattern carbines, SBRs, and pistols chambered in those calibers. Mounting is standard HUB 1.375x24, and the can also accepts JK Armament QD mounts directly. No muzzle device is included with this unit, so plan on pairing it with the HUB or JK mount of your choice. Finished in FDE Cerakote at 5.35 inches and 14.3 ounces bare, with a 1.72 inch diameter.
