The JK Armament 155 LT compensator end cap in .30 cal is a replacement front cap that turns the end of a JK 155 suppressor into a recoil-reducing compensator. JK Armament machines it with three rows of circumferential ports that redirect gas, reducing recoil and muzzle rise, and it does not need to be timed. It is made from T6-7075 billet aluminum in the LT grade and sized for .30 caliber rifles, including 7.62mm. The 1-1/2-inch wrench flats make swapping it a quick job with no special tools. Competition shooters and hunters who want less felt recoil are the natural fit.
