Jk Jk155Hpmb28 155 Hub Piston Mnt 1/2X28 Raw

The JK Armament HUB Piston Mount for 1/2x28 barrels is a precision-engineered suppressor mounting system designed for shooters running JK's piston-based suppressor platform. This raw aluminum and stainless steel construction delivers a clean, repeatable interface between your 9mm barrel and suppressor, giving you the modularity and reliability that serious shooters demand for both range sessions and hunting applications. Whether you're building a dedicated 9mm host or retrofitting an existing upper, the HUB Piston Mount handles the job with the kind of no-frills durability JK Armament is known for.

Raw finish means you get bare metal—no anodizing or coating. That's intentional: it gives you a clean mounting surface and lets you finish it however your build demands. Setup is straightforward: thread it onto your 1/2x28 barrel and pair it with a compatible JK HUB suppressor. The piston design isolates the suppressor from your barrel, reducing first-round pop and delivering more consistent sound reduction shot to shot. For suppressed 9mm shooters who refuse compromise, this is the mounting hardware that earns its spot on the gun.

JK Armament backs this component with the engineering you'd expect from a company that tests everything. If you run a JK suppressor platform or are considering one, this mount is the bridge between your barrel and quieter, cleaner shooting.

Frequently Asked Questions

What barrels does the JK HUB Piston Mount fit?

This mount is designed for 1/2x28 threaded barrels in 9mm caliber. Verify your barrel's thread pitch before ordering.

Is this mount compatible with other suppressor brands?

No. This mount is engineered specifically for JK Armament's HUB suppressor platform. It is not compatible with other suppressor mounting systems.

Why is this a raw finish, and can I coat it?

Raw finish gives you a clean mounting surface and the flexibility to anodize, cerakote, or finish it to match your build. Many shooters prefer raw for this reason—you're not paying for a finish you might want to change.

Do I need special tools to install this mount?

Installation requires standard barrel-mounting tools and practices. Thread it onto your 1/2x28 barrel with appropriate force and locking method (as you would any muzzle device). Consult JK Armament's instructions for torque specifications and assembly details.
