Yankee Hill Machine Phantom .22 Suppressor | YHM-4380

The Yankee Hill Machine Phantom .22 (YHM-4380) is a lightweight direct-thread sound suppressor designed for rimfire platforms and other small-caliber firearms. It pairs a 7075-T6 aluminum blast chamber with a 6061-T6 outer tube and heat-treated 17-4 stainless steel baffles to balance weight and durability. The rear of the blast chamber doubles as the takedown tool for the muzzle cap to simplify maintenance and field disassembly. Its compact size and low mass suit training, precision rimfire shooting, and small-game applications where reduced report and minimal added weight are priorities.
