The Turbo K is getting the same treatment as its bigger brother the T3. This 5.56 NATO Suppressor features a design improvement to the baffles-resulting in 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 718 Inconel 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 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. The overall length measures 4.9 and weighs in at 11.7oz. When using YHMs Phantom Q.D. adapter, the overall length is 5.5 and weights in at 12 oz. Having an average sound pressure level of 138dB on a 16 AR shooting 55 grain ammo, the Turbo K-RB is within the hearing safe threshold of 140 dB. 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 Phantom Q.D. adapter, 2 suppressor wrenches and Q.D. flash hider. Minimum Barrel Lengths: 5.56 NATO: 10.5" minimum barrel length
