Designed to mount directly to Smith & Wesson M&P-M2.0 full-size, 9mm, and 40S&W handguns, this SCS-MP2 Solar-Charging Sight from Holosun features a green, circle-dot reticle and a multicoated lens for clear and unobstructed targeting and close and long ranges. The housing is made from 7075 T6 aluminum housing with an anodized finish, and the sight attaches directly to the slide without an adapter plate. The multiple reticle system has three options: a 2 MOA dot, a 32 MOA circle, and a combined reticle. The sight's green Super LED is powered by an internal rechargeable battery that uses an innovative solar charging system and multidirectional light sensors to automatically adjust brightness in dynamic situations. The sight also includes an intensity override function that locks the optic into a high-brightness mode for 30 minutes and a low power indicator that warns of low battery days before any necessary charging.
