Jk Armament HUB Piston Mount Features The Jk Armament HUB Piston Mount solves a core challenge of suppressing short recoil-operated pistols by isolating the suppressor s mass from the moving barrel which keeps the pistol cycling reliably under the added weight of a can. This mount threads directly into the base of the serialized suppressor tube using the HUB-standard 1-3/8x24 thread pitch replacing the JK 155 suppressor s taper mount or other accessory mount. Because the HUB thread standard is shared across the industry this mount is compatible with any other suppressor that uses HUB threading and has enough internal length roughly 1.8 inches to accommodate the booster housing. Finished in black nitride over an aluminum and stainless steel construction the mount resists wear and corrosion from repeated mounting cycles. Built specifically for pistol hosts this piston mount lets GLOCKs SIGs and nearly every other modern centerfire pistol run suppressed without sacrificing the reliable short recoil cycling the platform depends on. At 1.55 inches in diameter and shipping as a 2-piece assembly the mount integrates cleanly with JK s suppressor lineup while remaining compatible with other HUB-threaded cans on the market. Shooters already running a JK 155 suppressor can convert it from a taper mount to a piston system without purchasing an entirely new suppressor. The Jk Armament HUB Piston Mount sold without a piston gives shooters a dependable interchangeable foundation for building a pistol-specific suppression setup.
