YHM’s .30 caliber sound suppressor, the Resonator® R2, was created to provide the shooting enthusiast a quiet, lightweight and cost effective suppressor. The notched rim and tri-port muzzle on the end cap make it stand out among the crowd. Capable of being used on multiple calibers and host weapons, the Resonator® R2 can be used on rifle calibers ranging from .17 HMR through 300 RUM making it a great choice for all shooters. Like the Turbo® T2, the Resonator® R2 uses a tubeless design which consists of heat treated 17-4 stainless steel and a heat treated 718 Inconel blast baffle which allows the suppressor to be full auto rated and designed for rigorous use. Includes YHM-4302 Q.D.
