Strike Industries is proud to introduce a revolutionary new product. The Universal (Optics) Mount for Glock. It has one of the lowest bore axises in the industry without the hassle and cost of cutting your slide! We have put many hours and 1000's of rounds down range with most of the more popular red dot optics on the market with no problems what so ever! This includes the Burris* fast* fire* II & III, Leupold* delta point* reflex sights, Docters* II & III, EoTech* (MRDS*), Trijicon* RMR* and many others. The mount itself is secured to the slide via the dovetail with 6 set screws.
