Radian Guardian for Glock MOS – Fits Holosun 407C/507C + SIX™ Backup Sights, TRU‑SEAL & STUD‑LOK

Description
Purpose-built for durability, precision, and reliability, the Radian Guardian is a rugged optic guard that seamlessly integrates with Glock MOS pistols and Holosun 407C/507C red dot sights. Whether you're on duty, in competition, or relying on your carry setup, this optic protector provides unmatched retention and environmental sealing for your optics — engineered to shield against water, dirt, and impact without compromising performance.

The Guardian’s TRU‑SEAL interface ensures moisture-proof integration between your optic and slide, while the STUD‑LOK mounting system locks everything down with hardened steel threads for unmatched stability. Built from aircraft-grade 7075 aluminum and hardcoat anodized, this is more than a mount — it’s an armored foundation for your red dot.
