Radian Weapons G1501 Guardian Optic Guard with Stealth Sights - Black Anodized Aluminum RMR Mount for Glock MOS Handguns

The Radian Weapons G1501 Guardian Optic Guard with Stealth Sights is a purpose-built RMR mount system for Glock MOS handguns that combines rock-solid optic mounting with integrated backup iron sights—a combination that appeals to shooters who demand redundancy without compromise. Whether you're running a carry gun, a competition rig, or a duty setup, this system keeps your red dot secure while giving you a failsafe if your optic goes down.

Radian engineered the Guardian around the principle that a red dot is only as good as its mounting. The TRU-SEAL design uses O-rings on the mounting screws to lock out moisture and prevent corrosion in the threads—a detail that matters if your gun lives in a holster, a truck, or anywhere humidity creeps in. The STUD-LOK threaded stud-and-nut interface replaces traditional screws with a more robust design that increases thread engagement and shear resistance, meaning your optic stays planted under recoil and isn't going anywhere.

The real differentiator here is the Stealth Sights system: six integrated backup iron sights built into the guard itself. They're low-profile, snag-free, and designed to co-witness low with your optic, so they stay out of your sight picture until you need them. If your red dot fails—battery dies, lens fogging, whatever—you've got precise aiming without fumbling for a separate rear sight or wasting seconds. It's the wingman you hope never to need but are glad to have.

Built from 7075 aluminum with Type III hard anodize and custom stainless steel fasteners, the Guardian is engineered to take hard use. The included mounting hardware—screws, O-rings, studs, and self-locking nuts—gives you everything needed to mount it to your Glock MOS slide.
