Radian Weapons G1002 Guardian Optic Guard - Black Anodized Aluminum, EPS Mount for Glock MOS Handgun

A red dot on your carry gun is only as good as its mounting system—and the Radian Weapons Guardian Optic Guard brings real engineering to that job. This EPS mount for Glock MOS handguns wraps your optic in multi-directional protection: a machined aluminum shield guards the top, front, and sides of your sight, keeping it safe from the snags, bumps, and impacts that happen in a working gun. Built from 7075 aluminum and hard anodized for durability, the Guardian is designed for shooters who rely on their pistol and aren't willing to compromise on optic security.

Protection means nothing if the mount itself fails. Radian engineered the Guardian with their STUD-LOK threaded mounting interface—a proprietary system that delivers longer thread engagement and greater holding power than standard dovetail mounts, with increased shear resistance. That translates to confidence in how your optic sits on your slide. The TRU-SEAL design pre-installs O-rings on the mounting screws, creating a watertight seal between the plate and your slide. This seals out moisture and corrosion in the mounting threads, a real advantage if your gun sees anything beyond the range.

The Guardian mounts directly to Glock MOS-pattern slides and accepts Holosun EPS optics. The design also leaves room for optional backup iron sights forward of the optic, so you retain a clean, unobstructed sight picture if you choose to run them. For shooters running a modern compact or subcompact carry gun with an optic, this is the kind of equipment detail that pays for itself the moment you need it.
