The choke tubes feature Triple Shot technology to reduce pellet deformation with a shorter firing chain and fewer unfolds. Three graduated rings in the parallel section of the choke allow a smoother transition to the final choke. These choke tubes are worn to reduce muzzle jump and recoil. Made from high-grade 17-4 stainless steel, Cremator tubes can be installed and removed without a wrench. Enjoy the spectacular performance of today's high-end ammunition by adopting the best choke tube technology!
