This 5.56 NATO Suppressor features reduced blowback-when compared to the previous model. The Turbo K-RB utilizes a tubeless design made from heat treated 17-4 stainless steel along with a heat treated blast baffle. The combination of these materials allows the suppressor to be designed for rigorous use. The blast chamber of the Turbo K-RB is threaded to the popular 1.375″-24 HUB thread which allows it to utilize many available mounting options. The notched rim and tri-port muzzle on the end cap make it stand out among the crowd. The Turbo K-RB is built with the same care, quality, and attention to detail that has defined the YHM brand for generations. The Turbo K-RB ships with the 1/2″ x 28 Phantom Q.D. adapter, (1) YHM-2007, (1) YHM-2146, and Q.D. flash hider or QD muzzle brake.
