Radian Guardian Optic Guard for Glock MOS RMR Black

The Radian Guardian Optic Guard is a mounting and protection system designed for RMR-style red dot optics on Glock MOS slides. It is machined from 7075 aluminum and finished with a hard-anodized black coating to resist corrosion. The design provides top, front and side impact protection while maintaining an unobstructed iron sight picture when backup sights are used forward. The mount employs Radian’s STUD-LOK threaded stud/nut interface and TRU-SEAL O-rings for a secure, watertight attachment to the slide.
