JK Armament 155 RPX 9K

The JK Armament 155 RPX 9K is a compact variant of the RPX suppressor platform, designed for use with 9mm pistols and pistol caliber carbines. It features a modular baffle system that allows users to configure overall length and weight to suit their firearm setup. The suppressor ships with a 1/2-28 piston and booster assembly, making it compatible with common threaded 9mm pistol barrels out of the box.

Constructed from titanium and billet aluminum, the RPX 9K supports use across a wide range of pistol and select rifle calibers within defined barrel length restrictions. It includes a high-flow flash-hiding end cap and is available in Black or FDE finishes to match various firearm configurations.
