Holosun has solidified their reputation as a manufacturer of some of the highest quality and most affordable electro-optics and now they have a brand new innovation in the form of the SCS or Solar Charging Sight.This optic combines a rechargeable built-in battery with a solar charging panel to deliver a nearly limitless battery life.The SCS can potentially operate indefinitely using an internal rechargeable 20 000-hour power reserve meaning under even moderate exposure to bright light you will never need to change batteries again.The SCS also includes an intensity override function which locks the optic into a high brightness mode for 30 minutes and a low power indicator which warns of low battery days before charging is needed.With multiple models which are designed to mount directly to some of the most popular optics ready pistols on the market the SCS lineup represents a new generation of pistol mounted sighting solutions.Features / SpecsHolosun Item Number: SCS-M-GRPistol Mounted OpticReticle Color: GreenMulti Reticle System (2 MOA Dot and 32 MOA Circle)Direct Mount to Full Size Glock MOS HandgunsInternal Rechargeable BatteryUnlimited Battery LifeSolar Failsafe Technology for Backup Power SourceAuto Adjusting Brightness Control with Override Function1 MOA Adjustment per Click +/- 30 MOA Adjustment RangeMultilayer Reflective Glass CoatingsTitanium HousingWaterproof Rating: IP68Window Size: 0.58" x 0.77"Dimensions: 1.93" x 1.03" x 0.91"Weight: 1.3 ozAnodized Black FinishFitsFull Size Glock MOS Pistols(does not fit Glock 43 43X 48 MOS)IncludesMounting ScrewsMulti Tool
