JK Armament 155 LT Compensator End Cap (45 Cal), Black

JK Armament 155 LT Compensator End Cap, .45 caliber, Black

The JK Armament 155 LT Compensator End Cap adds a compensating function at the front of a compatible suppressor. The .45 caliber opening and JK 155 interface define the fitment, while the black finish keeps the completed assembly visually consistent.

7075-T6 billet aluminum construction keeps the front component light without adding the mass of a steel cap.

Compensation at the Suppressor Front

Three circumferential rows of ports redirect gas to help reduce recoil and muzzle movement. The symmetrical layout does not require rotational timing, so the compensating function is integrated into the end cap itself.

Made for the Correct Suppressor Interface

The cap has a 1.55-inch outside diameter and 1.5-inch wrench flats. It is intended for compatible JK 155 components. Outside diameter alone does not establish interchangeability with a different series or another manufacturer's suppressor.

Bore Size and Cartridge Rating

The end-cap opening must provide appropriate clearance for the projectile. The .45 caliber designation identifies the cap's bore application; it does not increase the suppressor body's cartridge, pressure, or firing-schedule rating. Select the cap as part of a fully compatible suppressor and firearm combination.
