RADIAN GUARDIAN EPS+SIGHTS FOR GLK

Description

The Radian Weapons Guardian is built for Glock MOS pistol owners who run a red dot and want more than a bare optic plate between their optic and the real world. The mount is machined from 7075 aluminum and finished in hard anodize, a material and process chosen for impact resistance rather than looks alone. The guard wraps the Holosun EPS from the top, front, and sides, so a drop or a hard contact against a barricade does not transfer directly to the optic body.

Radian’s STUD-LOK system replaces the standard screw-down attachment with a threaded stud and nut arrangement that provides substantially longer thread engagement than a conventional screw. More thread engagement means more resistance to the shear forces that repeat recoil cycles apply to a mounted optic — the connection stays tight rather than gradually walking loose. The TRU-SEAL design handles moisture: pre-installed O-rings on the mounting screws form a seal at the interface, keeping water out of the joint and reducing the corrosion that would otherwise develop between dissimilar metals over time.

The included Stealth back-up iron sights co-witness through the optic guard rather than being blocked by it. If the EPS fails, the shooter transitions to iron sights without having to remove any hardware. The whole assembly fits the Glock MOS adapter system, so installation uses the existing MOS mounting points on the slide — no machining, no permanent modification to the pistol.
