JK Armament HUB Piston Mount 9mm 1/2x28 Aluminum/Stainless Steel Black Nitride

The JK Armament HUB Piston Mount is a compact booster assembly that installs in place of your suppressor's taper mount, threading directly onto a pistol barrel to deliver reliable operation of JK 155 silencers - and other HUB-pattern pistol suppressors - on 9mm semi-automatic, centerfire handguns.

Purpose-built for short-recoil pistol platforms, the piston moves with the slide cycle to unlock the suppressor at the correct moment, eliminating sluggish actions or tie-ups during rapid fire. It threads onto any standard 1/2x28 barrel and is a clean drop-in upgrade for shooters wanting to run a JK 155 or any compatible HUB-mount can on a duty, carry, or range pistol.

Machined from a blend of aluminum and stainless steel and finished in a hard, low-glare black nitride coating, the HUB Piston Mount pairs cleanly with most pistol finishes while resisting wear and corrosion. The compact footprint keeps overall length and weight down, so your suppressed rig stays balanced and pointable.
