JK ARMAMENT JK155HPM HUB Piston Mount | Aluminum/Stainless

The JK ARMAMENT JK155HPM HUB Piston Mount is a suppressor mount designed to isolate the suppressor from a moving pistol barrel to maintain reliable operation on short recoil-operated, semi-automatic pistols. It installs in place of the JK 155 taper mount or other compatible mount accessory by threading directly into the base of a serialized suppressor tube. The mount uses HUB-standard threading and is intended for use with HUB-thread suppressors that provide sufficient internal length to accept the booster housing.

Common applications include range use for suppressed shooting and competition where reliable cyclic function on short-recoil pistols is required. The unit ships without a piston and is compatible with many modern, centerfire pistols that operate via short-recoil action.
