JK ARMAMENT | JK155HPM HUB Piston Mount

The JK ARMAMENT JK155HPM HUB Piston Mount isolates the suppressor from the moving barrel to maintain reliable operation of short-recoil, semi-automatic pistols such as GLOCKs and SIGs. It installs in place of the JK 155 suppressor taper mount and threads directly into the base of a serialized suppressor tube. The mount uses the HUB-standard thread interface and is intended to provide a durable, serviceable connection when host and suppressor geometry are compatible.
