JK Armament HUB Piston Mount 9mm 1/2x28 Aluminum/Stainless Steel - Raw

The JK Armament HUB Piston Mount is a piston-style suppressor mounting interface built to deliver reliable operation of JK 155 series pistol suppressors on semi-automatic centerfire pistols. Purpose-built for 9mm Luger host pistols threaded in 1/2"x28, the HUB is machined from a combination of aluminum and stainless steel and offered here in a Raw, uncoated finish.

The piston-driven design keeps the suppressor baffle stack mechanically locked to the barrel while the slide cycles, smoothing semi-auto function, slowing slide velocity, and reducing gas blowback toward the shooter. Compatible with JK Armament 155 series suppressors and other brands' pistol suppressors rated for piston operation, the HUB Piston Mount weighs approximately 4.50 oz and is built around the standard 9mm host pistol thread pattern used across most modern handgun platforms.
