Radian Guardian Optic Guard — Glock MOS, Holosun EPS

Description

The Radian Weapons Guardian Optic Guard is an optic mounting system and protective guard designed for Glock MOS slides and compatible with Holosun EPS footprint optics. Machined from 7075 aluminum and finished with a hard anodize, the Guardian combines a robust protective shell with a secure mounting interface. Radian’s STUD-LOK threaded stud/nut system increases thread engagement and shear resistance while the TRU-SEAL design with pre-installed O-rings eliminates the need for an added sealing plate. The guard is engineered to preserve an unobstructed irons-forward sight picture when using optional back-up sights.
