JK Armament HUB Piston Mount 1.55" Aluminum/Stainless Steel Black Nitride - No Piston

The JK Armament HUB Piston Mount is a precision suppressor mounting interface designed for use with JK 155 series pistol suppressors and other compatible pistol silencers. Engineered to deliver reliable operation on semi-automatic centerfire pistols, this mount provides a secure, repeatable lockup between the suppressor and the host pistol's barrel.

The housing is machined from aluminum and stainless steel and finished in black nitride for excellent corrosion resistance, durability, and a clean low-profile look. The mount features a 1.55" diameter housing sized for the JK 155 suppressor family and comparable pistol silencers that use the HUB (booster) mounting standard.

Important: This listing is for the HUB mount only - no piston is included. The operating piston (which must be matched to the host pistol's caliber and barrel geometry) is sold separately. Pick the correct piston for your host pistol to ensure proper cycling and reliable function.
