Radian Guardian for Glock MOS – Fits Holosun 407C/507C with TRU‑SEAL & STUD‑LOK

Description
The Radian Guardian is a precision-engineered optic guard designed to enhance durability, mount stability, and environmental sealing for Glock MOS pistols using Holosun 407C or 507C optics. Whether you're carrying for duty or dialing in a competition rig, the Guardian ensures your red dot is shielded from impact, water, and debris — all without compromising performance or zero.

Crafted from aircraft-grade 7075‑T6 billet aluminum and finished with a Type III hardcoat anodizing, the Guardian pairs seamlessly with your slide while reinforcing optic retention using Radian’s advanced STUD‑LOK mounting system. The built-in TRU‑SEAL barrier system prevents moisture from infiltrating the slide-to-optic interface, ensuring reliable operation in harsh conditions.
