The JK Armament 155 HUB Piston Mount, sold here as the mount only with no piston (brand part no. JK155HPM), is built to give reliable operation of JK 155 suppressors on semi-automatic centerfire pistols. Jk Armament designed it to isolate the suppressor from the moving barrel, which keeps short recoil platforms such as GLOCKs and SIGs running. It threads directly into suppressors with the HUB-standard 1-3/8×24 interface. Any HUB-threaded suppressor with enough internal length can use it, not only the JK 155. A piston is a separate purchase.

Key Specifications

• The housing is 17-4PH stainless steel, a strong, corrosion-resistant material for a part that handles recoil.

• The mount adds .43 inch of length, a small increase to the overall package.
• It is built for semi-automatic centerfire pistols, where the barrel moves under recoil.
• It isolates the suppressor from the moving barrel, which maintains function on short recoil platforms like GLOCKs and SIGs.
