JK Armament HUB Piston Mount 9mm 1/2x28 Thread Nitride Black

The JK Armament HUB Piston Mount is designed for reliable operation with short recoil-operated semi-automatic pistols including Glock, SIG, and other modern centerfire pistols. By isolating the suppressor from the moving barrel, this mount maintains consistent function. Features 1/2x28 thread pitch for 9mm compatibility and installs directly into JK 155 suppressors with HUB-standard 1.375x24 threading. Constructed from aluminum and stainless steel with nitride finish for durability and corrosion resistance.
