JK Armament RPX 9k w/Booster, Black
Designed for 9mm pistol performance right out of the box, the JK 155 RPX 9K ships with a pistol booster and 1/2-28 piston already installed. It’s a shorter variant of the Mission-Configurable RPX platform that’s ready-to-rock on your GLOCK or other semi-auto, 9mm pistol with a threaded barrel. The JK 155 RPX 9K’s high-flow, flash-hiding end cap is optimized for reliable function on boosted pistols and reduces gas and debris blowback for the operator.
Though it ships configured for pistol use, the JK 155 RPX 9K is capable of so much more! . . .
Built on JK’s most advanced rifle-pistol baffle geometry for excellent sound and pressure management across a wide range of cartridges, the JK 155 RPX 9K, with the booster swapped for a fixed mount option, is perfect for 9mm pistol caliber carbines, 38/357 lever actions, and anything chambered in 300 Blackout, 350 Legend, 8.6 Blackout, 338 ARC, etc. It’s rated for magnum pressures and, with its 9mm bore size, it’s ready for duty across a wide range of firearms and calibers!
With booster assembly, the RPX 9K weighs only 7.5 to 13.1 ounces and can be quickly configured to lengths between 3.3 and 7.25 inches. It’s available in Black and FDE.
