The HolosunA(R) SCS (Solar Charging Sight) is a direct-attachment optic designed exclusively for full-sized M&P M2.0 pistols, combining simple solar charging and multi-reticle versatility in Holosun's lowest-profile pistol optic for use with standard-height iron sights. The SCS reimagines Holosun's proven Solar Failsafe system as a primary power source, so you never need to mess with batteries or wall charging. Simply expose the unit to occasional bright light, and the SCS will recharge itself. But there's more to the SCS than just solar simplicity. Like many of Holosun's reflex sights, the SCS features the Multi-Reticle System: you choose between a 2 MOA dot, 32 MOA circle, or both. The SCS is crafted from Grade 5 titanium for superior durability, and is IP67 certified waterproof for absolute reliability in all weather. If you want the best for your pistol, look no further.
