The Cremator choke tubes are equipped with Triple Shot technology to reduce pellet deformation with a shortened shot string and fewer flyers. Three graduated rings in the parallel section of the starter allow for a more progressive transition to the final constriction. These choke tubes are ported to reduce muzzle jump and recoil. Made from premium 17-4 stainless steel, Cremator tubes install and remove without a key. Enjoy the spectacular performance of today's premium ammunition by embracing the best choke tube technology!
