JK Armament’s most-requested accessory is now available in an extremely durable black nitride finish. The JK HUB Piston Mount is lightweight, compact and delivers reliable operation of JK 155 suppressors as well other brands of pistol suppressors when used on semi-automatic, centerfire pistols.
Select from three different models:
- JK HUB Piston Mount without a piston
- JK HUB Piston Mount Bundle with 1/2×28 tpi (9mm) piston
- JK HUB Piston Mount Bundle with .578×28 tpi (.45cal /10mm) piston
By isolating the suppressor from the moving barrel, the JK HUB Piston Mount (often referred to as a “booster” or a “Nielsen Device”) maintains reliable operation of nearly every kind of short-recoil-operated, semi-automatic pistol.
The JK HUB Piston Mount installs in place of the JK 155 suppressor taper mount or other mount accessory, threading directly into the base of the serialized suppressor tube with its HUB-standard 13⁄8×24 (1.375×24) tpi. 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 (approximately 1.8 inches).
The size, reliablity and price of the the JK HUB Piston Mount make it a great way to suppress your semi-automatic pistol with a JK 155 silencer, other HUB-compatible pistol or hybrid silencer and still maintain proper function of your pistol.
