JK Armament HUB Piston Mount 45 Cal .578x28 Black Nitride Aluminum/Stainless Steel

The JK Armament HUB Piston Mount delivers reliable operation of JK 155 suppressors, plus other brands' pistol suppressors, on semi-automatic centerfire pistols. The HUB piston standard lets a single mount cover a wide range of host pistols without requiring individual booster assemblies.

Built from aluminum with stainless steel internals and a corrosion-resistant nitride finish, this piston mount keeps weight down at the muzzle while delivering the repeatable cycling host pistols demand. The .578"x28 thread pattern drops directly onto 45 caliber pistol barrels, making it a straightforward addition to any JK 155 or HUB-compatible suppressor set-up.
