JK ARMAMENT | JK155HPM587X28 HUB Piston Mount | 45Cal/10mm

The JK ARMAMENT HUB piston mount isolates the suppressor from the moving barrel to maintain reliable operation of short recoil-operated, semi-automatic pistols. It installs in place of a JK 155 taper mount or other compatible mount accessory and threads directly into the base of a serialized suppressor tube. The mount is compatible with HUB-threaded suppressors that have sufficient internal length to accommodate the booster housing (approx 1.8). Typical applications include range and competition use where suppressed operation is desired, and gunsmithing or platform adaptation work for suppressed pistols.
