The Jk Armament JK155HPM28BN Hub Piston Mount 9mm is engineered to keep short recoil pistols running smoothly when a suppressor is installed. Designed around the HUB standard, it threads directly into compatible suppressor tubes and provides a spring-loaded booster assembly that lets the can move independently from the barrel for consistent cycling and reliable performance.

This piston mount replaces the taper mount on JK 155 series suppressors or other HUB-threaded cans and interfaces with 1/2x28 threaded 9mm barrels. Its aluminum body and stainless steel piston are finished in black nitride for durability and corrosion resistance, making it a practical upgrade for range use, training, or everyday shooting with a suppressed centerfire pistol. JK Armament’s attention to detail and thoughtful engineering are evident in the compact, robust design of this booster.
