Great product - Holosun EPS-Carry 1x0.58x0.77in Reflex Red Dot Sight w/Multiple Reticle System

"Holosun EPS CARRY MRS" Exact words for solar panel fail safe type, is Great product. "Holosun SCS CARRY" Great also. See each features. Both use a K series type footprint and can direct mount without stupid mounting plates, and co witness regular height factory sights. "Holosun SCS MOS" type for regular Glock MOS cut slide type is another decent one, although not a double glass design to keep dust off reticle emitter. Always practice with regular sights also.
