Yankee Hill Sidewinder M2 Suppressor, .45 Caliber, 9.3-Inch, Black

The Yankee Hill Sidewinder M2 (brand part no. YHM-2070-28) is a .45 caliber suppressor finished in black stainless steel and aluminum, built to deliver features typically found on more expensive cans at an affordable price. Yankee Hill Machine redesigned the booster system around the industry’s common piston standard, so pistons from SilencerCo, Rugged, Dead Air, and other brands are interchangeable with the Sidewinder M2. The Sidewinder M2 favors .45-caliber pistol shooters who want piston-driven reliability without being locked into a single brand’s ecosystem.
