Jk Jk155Hpmbn 155 Hub Piston Mnt No Pist Blk

The JK Armament JK155HPMBN is a 155 hub piston mount designed for shooters running suppressed pistols who want a modular, reliable mounting solution. This is the mount body only—piston sold separately—giving you flexibility to pair it with the right piston for your barrel and suppressor setup. Built from nitride-treated aluminum and stainless steel, it's engineered to handle the wear and corrosion that come with suppressed fire while keeping tolerances tight enough for consistent performance.

JK Armament's hub piston system is purpose-built for pistol shooters serious about suppression. The 155 hub is their standard platform, trusted by competitive shooters and hunters running cans on 9mm and other common handgun calibers. Nitride and stainless construction means you're not fighting rust or erosion—critical when your mount lives inside a suppressor and catches unburned powder and fouling shot after shot.

If you're already running a JK suppressor or looking to build a suppressed pistol rig with a proven system, this hub mount gives you the core component without forcing you to buy a piston you might not need. Pair it with the appropriate JK piston for your barrel diameter and let the modular design do the work.
