The  JK Armament PRO-KOR 556K is a mid- to full-size hard-use 5.56 rifle silencer with very high suppression performance with a balanced flow rate.  The silencer is printed from Haynes 282 alloy and uses advanced hybrid geometry to achieve efficient blast propagation control for its size. Blast hazard is projected forward, away from the operator. The silencer is HUB-mount compatible and its end cap is replaceable. This silencer is significantly different from previous modular JK Armament silencer designs and presents an example of the rapid advancement of rifle silencer suppression technology.

In this review, the JK Armament PRO-KOR 556K performance metrics depend upon suppressing a supersonic centerfire rifle cartridge on a short-barrel gas-operated rifle, which is an incredibly difficult task. How would the JK Armament PRO-KOR 556K perform on your MK18 with a 10.3-in barrel?
