Radian Guardian for Glock MOS – Designed for Holosun EPS with SIX Backup Sights

When precision and durability matter most, the Radian Guardian for Glock MOS stands above the rest. Built specifically for Holosun EPS optics, this optic guard is engineered for shooters who demand secure mounting, waterproof protection, and modular backup sight integration — all in one sleek profile.

Crafted from aircraft-grade 7075-T6 billet aluminum and finished with a hardcoat anodized treatment, the Guardian delivers industry-leading strength without unnecessary bulk. Its proprietary TRU‑SEAL system creates a moisture-resistant barrier between your slide and optic, keeping debris and water out. The STUD‑LOK mounting design features embedded steel threads to ensure a torque-stable connection, reducing the risk of stripping during multiple optic installs.

This version supports the optional integration of SIX™ backup sights, giving you passive co-witness capability in case of optic failure. Perfect for EDC, duty use, or tactical range setups.
