JK Armament HUB Piston Mount - 45 Caliber, .578"x28 The JK Armament HUB Piston Mount is engineered to maintain the reliable operation of short recoil-operated, semi-automatic pistols by isolating the suppressor from the moving barrel. Compatible with GLOCKs, SIGs, and nearly every modern centerfire pistol, this mount installs directly in place of the JK 155 suppressor&';s taper mount or other mount accessory. It threads directly into the base of the serialized suppressor tube using the HUB-standard 1-3/8x24 (1.375x24) thread pitch, making it universally compatible with any suppressor on the market featuring HUB threads and sufficient internal length to accommodate the booster housing (approximately 1.8"). Constructed from nitride-treated aluminum and stainless steel, this piston mount is built to withstand the demands of repeated use while resisting wear and corrosion.
