Yankee Hill Machine Resonator K 30Cal Suppressor
The Yankee Hill Machine Resonator K 30Cal suppressor is a lightweight, cost-effective silencer engineered for shooters who demand precision without carrying extra weight. Built from heat-treated 17-4 stainless steel with a 718 Inconel blast baffle, this .30 caliber suppressor delivers genuine noise reduction across rifle calibers from .17 HMR through .300 Ultra Mag. Whether you're running a bolt-action hunting rifle, an AR platform, or a precision semi-auto, the Resonator K threads onto the industry-standard 1-3/8-24 connection, giving you flexibility in mounting options and quick-detach adapters.
At 9.6 ounces (without mount) or 12.4 ounces with the included Phantom Q.D. Adapter, this suppressor cuts weight without sacrificing durability or sound suppression. The tubeless design and full-auto rating mean you're buying a can built to take punishment—whether you're sending rounds downrange at a static range or putting in work in the field. The redesigned end cap actively reduces flash signature, helping keep your position concealed in low-light scenarios. It measures just 1.562 inches in diameter and 4.8 inches in length (5.65 inches with the quick-detach mount), so it won't turn your rifle into an unwieldy package.
Tested suppression data shows you what to expect: .308 Winchester delivers 137 dB at the ear and 144 dB at the muzzle, while .300 Blackout runs 142 dB ear / 147 dB muzzle. Comes ready to install with the Phantom Q.D. Adapter and two suppressor wrenches—everything you need except the tax stamp. Finished in matte black Cerakote for durability and low profile.
