Radian Weapons Guardian Optic Guard for Glock MOS – Black

The Radian Weapons Guardian Optic Guard is a machined optic mounting and protective system designed for Glock MOS slides using the EPS (Holosun EPS) footprint. Constructed from 7075 aluminum with a hard black anodized finish, the Guardian provides top, front and side protection for pistol red dot optics while integrating Radian's STUD-LOK threaded stud and nut mounting interface and TRU-SEAL O-ring sealing.

STUD-LOK mounting increases thread engagement and shear resistance compared with standard mounting hardware. TRU-SEAL uses pre-installed O-rings on the mounting screws to seal the plate to the slide and limit moisture intrusion into mounting threads.
