JK ARMAMENT HUB Piston Mount — 9mm, Nitride

Description

The JK ARMAMENT HUB piston mount interfaces a suppressor to short-recoil, semi-automatic pistols and is intended to isolate the suppressor from the moving barrel to preserve reliable cycling. It installs in place of a JK 155 taper mount and threads into the base of compatible serialized suppressor tubes that use the HUB interface. The mount is built from aluminum and stainless steel components with a nitride finish for abrasion resistance and durability. Designed for use with 9mm applications, the HUB piston mount supports setups that require a booster/booster housing inside the suppressor.
