The JK Armament JK155HPMBN Hub Piston Mount is engineered to keep your suppressor running smoothly on short recoil–operated, semi-automatic pistols. Designed for use with the JK 155 series and other HUB-threaded suppressors, this aluminum and stainless steel mount uses a durable nitride finish and a two-piece booster assembly to isolate the moving barrel from the weight of the can, helping maintain reliable cycling and consistent performance.

This piston mount is ideal for shooters who run suppressed centerfire pistols for training, range use, or practical shooting and want dependable operation without adding unnecessary complexity. Threading directly into the base of compatible suppressor tubes with HUB-standard 1-3/8x24 threads, it offers a straightforward way to convert your can for pistol use while leveraging JK Armament’s attention to detail and proven suppressor accessory design.
