JK Armament HUB Piston Mount 45 Cal/10mm .578x28 Aluminum/Stainless Steel - Raw

The JK Armament HUB Piston Mount delivers reliable operation of your JK 155 suppressor and other HUB-compatible pistol suppressors on short-recoil, semi-automatic pistols. This specific variant is cut with a .578"x28 thread pitch for installation on .45 caliber and 10mm host pistols, installing in place of the factory JK 155 taper mount and threading directly to the barrel.

The piston design allows the slide to cycle freely while the suppressor remains locked to the barrel, making it an ideal solution for locked-breech pistols such as GLOCK-pattern handguns. The HUB interface on the opposite end provides broad compatibility across suppressor brands using the same HUB standard.

Built from a combination of aluminum and stainless steel with an uncoated raw finish, the HUB Piston Mount keeps added weight and length to a minimum while delivering the durability needed for hard-use training and everyday carry. It is a straightforward upgrade or replacement mount for any shooter running a JK 155 or a third-party HUB-compatible pistol suppressor on a .45 ACP or 10mm pistol.
