Yankee Hill Machine Co Sidewinder M2 Features The Yankee Hill Machine Co Sidewinder M2 suppressor is built around a high-efficiency mono-core baffle machined from 7075-T6 aluminum with Class 3 hardcoat anodize housed in a 6061-T6 aircraft-grade aluminum outer tube finished to the same standard for a lightweight high-strength construction that delivers longevity through sustained use. The piston Nielsen sleeve and blast baffle are constructed from heat-treated 17-4PH stainless steel for exceptional corrosion and wear resistance that holds up through extreme temperatures without degradation. Averaging 133 dB dry on a Glock G21 with 230gr FMJ ammunition tested to Mil-Std 1474D the Sidewinder M2 delivers effective sound suppression in a lightweight aluminum package with wet shooting providing even quieter results. The redesigned booster system uses the industry s unofficial standard piston providing cross-compatibility with pistons from SilencerCo Rugged Dead Air and other major manufacturers while the new rear cap allows tool-free piston swaps for fast configuration changes. Twelve index points allow point-of-impact adjustment while the suppressor remains attached to the host firearm and the redesigned front cap provides better engagement with the included takedown tool for easier servicing. Full user serviceability allows both the baffle and Nielsen device to be removed for cleaning and maintenance ensuring the Sidewinder M2 performs consistently across its full service life. Yankee Hill Machine Co engineered the Sidewinder M2 to deliver features typically found on more expensive suppressor models in an affordable lightweight aluminum package optimized for .45 ACP semi-automatic pistol platforms.
