The YHM Turbo K-RB is a 5.56 NATO suppressor designed with reduced blowback compared to previous models. It features a tubeless design made from heat-treated 17-4 stainless steel and a Cobalt 6 blast baffle, making it full-auto rated and built for rigorous use. The blast chamber is threaded to the popular 1.375"-24 HUB thread, allowing for a variety of mounting options. Its unique notched rim and tri-port muzzle on the end cap set it apart. The Turbo K-RB ships with a 1/2" x 28 Phantom Q.D. adapter, a YHM-2007, a YHM-2146, and a QD Flash Hider. Cartridge - Minimum Barrel Length 5.56mm NATO - 10"
