YANKEE HILL MACHINE SIDEWINDER M2 9MM HANDGUN SUPPRESSOR YHM SIDEWINDER M2 9mm Piston - 1/2x28 Black Meet the Sidewinder M2 Suppressor-an affordable, lightweight gem packed with premium features you'd usually find on pricier models. It's been reimagined with a booster system that now accepts the industry's unofficial standard piston. Good news-pistons from respected brands like SilencerCo, Rugged, and Dead Air work seamlessly with the Sidewinder M2, and vice versa. Plus, no tools are needed for piston swaps, thanks to the new rear cap. The front cap's redesign makes it a breeze to engage with takedown tools for easier maintenance.
