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 Cobalt 6 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 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.
