Hammett, ID – JK Armament’s #1 most-requested accessory is now available! The JK HUB Piston Mount delivers reliable operation of JK 155 suppressors (plus other brands’ pistol suppressors!) on semi-automatic, centerfire pistols. Our booster is lightweight, compact, and competitively priced!

By isolating the suppressor from the moving barrel, the JK HUB Piston Mount – available as a full kit HERE or sans piston HERE (for those who already own compatible pistons) – maintains reliable operation of short recoil-operated, semi-automatic pistols such as GLOCKs, SIGs, and nearly every other modern, centerfire pistol.

The JK HUB Piston Mount installs in place of your JK 155 suppressor’s taper mount or other mount accessory, threading directly into the base of the serialized suppressor tube with its HUB-standard 1-3/8x24 (1.375x24) thread pitch. This also makes the JK HUB Piston Mount compatible with any other suppressor on the market with HUB threads and enough internal length to accommodate the booster housing (approx 1.8”).

Reliable, compact, and affordable, the JK HUB Piston Mount is the best way to suppress your semi-auto pistol with your favorite JK 155 silencer or other HUB-compatible pistol or hybrid silencer and maintain proper function.

Additional booster piston thread sizes coming soon!

(1) JK HUB Piston Mount
