Like new Holosun SCS MOS pistol optic. Features the holosun multi reticle system, solar charging, adaptive brightness, and direct mount capability on Glock MOS slides. Optic is in like new condition and works perfectly. This came on a Glock package that I purchased recently and I already have another optic for that gun. No low ball offers, the sight retails for $350+. If you are seeing the post it is still available.
