Yankee Hill Machine Resonator R2 Supp .30Cal Qd 5/8-24 Mb
The Yankee Hill Machine Resonator R2 .30 Cal QD Suppressor with 5/8-24 Muzzle Brake is a lightweight, full-auto rated sound suppressor built for shooters who want serious noise reduction without breaking the bank. If you're running .308 Winchester, 300 Win Mag, or anything in between on a precision rifle, patrol carbine, or hunting build, the Resonator R2 delivers 135 dB of suppression in a compact, durable package that can handle whatever you put downrange.
YHM engineered the Resonator around a tubeless design using heat-treated 17-4 stainless steel and 718 Inconel baffles—the same materials and durability standards you'll find in their pricier cans. That full-auto rating means it's overbuilt for semi-auto use, so you're not compromising longevity or performance to keep weight and cost reasonable. At 16 ounces and just 7.825 inches long, it won't throw off your rifle's balance or create a barrel obstruction problem on shorter carbines.
The quick-detach mount system (YHM-4302 Q.D.) gets the can on and off your muzzle brake in seconds—no tools, no fussing. The suppressor is rated for calibers from .17 HMR all the way through .300 RUM, so if you've got a precision rifle, AR-10, or bolt gun in a common magnum cartridge, this one suppressor can do the work across multiple platforms. Finished in matte black Cerakote, it handles recoil, heat, and field use without showing wear.
Whether you're hunting, running the suppressor in precision rifle competitions, or simply wanting to preserve hearing on the range, the Resonator R2 is a no-nonsense suppressor that doesn't ask you to choose between performance and affordability.
