JK Armament HUB Piston Mount designed for 45 caliber suppressors with .578"x28 threading. Features nitride finish and aluminum/stainless steel construction. Isolates the suppressor from the moving barrel to maintain reliable operation of short recoil-operated semi-automatic pistols including Glocks, SIGs, and other modern centerfire pistols. Installs in place of JK 155 suppressor's taper mount, threading directly into the serialized suppressor tube with HUB-standard 1-3/8x24 thread pitch for compatibility with various suppressor systems.
