YHM Turbo K-RB 5.56mm Steel / Cobalt Suppressor - Phantom QD Adapter

YHM Turbo K-RB 5.56mm Steel / Cobalt Suppressor - Phantom QD Adapter

Upgrade your compact carbine with the Yankee Hill Machine (YHM) Turbo K-RB (Reduced Blowback) 5.56mm Suppressor Package with QD Muzzle Brake. Engineered to deliver significant sound attenuation in an ultra-short footprint, the Turbo K-RB features an updated flow-optimized interior that mitigates backpressure, gas face, and cyclic rate increases on semi-automatic and select-fire rifles. Manufactured using a tubeless design from heat-treated 17-4 PH stainless steel paired with a heavy-duty Cobalt 6 blast baffle, this compact silencer is fully full-auto rated and built to withstand harsh firing schedules.

Measuring just 4.6 inches long on its own and weighing only 8.7 ounces, the Turbo K-RB preserves the light, agile handling of short-barreled rifles and personal defense weapons. The rear blast chamber features industry-standard 1.375"-24 HUB threading, granting maximum mounting modularity. Shipping ready to mount with a 1/2x28 Phantom QD adapter, a Phantom QD muzzle brake, and two dedicated suppressor wrenches, the Turbo K-RB tames 5.56 NATO muzzle blast down to an ear-safe 138 dB on barrels as short as 10 inches.
