The Turbo(R) K utilizes a tubeless design made from heat-treated 17-4 stainless steel along with a heat-treated 718 Inconel(R) blast baffle. The combination of these materials allows the suppressor to be full auto-rated and designed for rigorous use. The blast chamber of the Turbo(R) K is threaded to the popular 1-3/8"-24 thread which allows it to utilize many available mounting options currently on the market. The notched rim and tri-port muzzle on the end cap make it stand out among the crowd.
