The YHM Sidewinder M2 is a direct-thread suppressor designed for lightweight, serviceable operation. It features a redesigned booster and a rear cap that allows piston swaps without tools, and a front cap revised for improved takedown-tool engagement. The unit is user-serviceable: the baffle stack and Nielsen device can be removed for cleaning and maintenance. Twelve index points permit point-of-impact adjustments while remaining mounted to the host firearm.
