The Radian Guardian optic guard protects a Holosun HS507COMP mounted on a Glock MOS-cut slide (Gen 4 / Gen 5 MOS). The steel housing wraps around the optic, so holster wear, bumps against door frames and weight-bearing falls land on the guard instead of the optic body and lens.
The 507COMP is an open-emitter competition and duty optic with a larger window. That window makes it fast to pick up the dot, but it also puts more exposed glass and housing out on the slide. The Guardian closes that gap for anyone who carries a 507COMP every day or runs it hard in training.

Includes: Guardian optic guard and mounting hardware.
Before you install: confirm your slide is MOS-cut and your optic is the HS507COMP, not the 507C or another model. A guard adds width around the optic, so check your holster for clearance. Torque the screws evenly, re-zero, and re-check the screws after the first range session.
