The Radian Guardian+Six is a machined aluminum optic guard with integrated backup sights for Glock MOS pistols, mounting to the MOS optic cut around a Trijicon RMR, Holosun EPS or Trijicon RCR footprint red dot.
The Guardian, plus integrated backup sights — optic protection and a co-witnessed iron sighting solution in one machined unit.
The Radian Guardian+Six adds integrated Stealth backup sights to the hardcoat-anodized aluminum Guardian optic guard. You get the same three-sided red-dot protection and rugged one-handed rack surface for your Glock MOS pistol, with a rear notch and front reference built in so you keep a usable sight picture if the dot ever fails. Machined to the specific optic footprint for an exact fit and a clear window.
How It Compares
Compare with the Radian Guardian Optic Guard for Glock MOS.
Key Features
- Optic guard + backup sights — protection and irons in one unit
- Fail-safe sighting — a usable picture if the dot dies
- Rugged one-handed rack surface — off a belt or a barricade
- Footprint-specific fit — hardcoat-anodized aluminum
Compatibility & Fitment
Fits Glock MOS-cut slides and mounts using the MOS optic screws. Each version is machined for a specific optic footprint — Trijicon RMR, Holosun EPS or Trijicon RCR — so select the one matching your sight and confirm your optic's footprint before ordering. It is not a universal shroud, and a mismatched footprint will not mount. Without the integrated sights, the same guard is the plain Guardian.

Frequently Asked Questions
Will the Guardian+Six fit my pistol and my optic?
It fits Glock MOS-cut slides and mounts using the MOS optic screws. The optic side is not universal — each version is machined for one footprint, and this listing covers the Trijicon RMR, Holosun EPS and Trijicon RCR. Confirm which footprint your red dot uses before ordering, because a mismatched version will not mount.
What do the integrated backup sights give me?
The shroud carries a rear notch and a front reference built into the machined body, so if the dot fails or the battery dies you still have a usable sight picture without adding separate irons to the slide. They are part of the same unit, so there is nothing extra to fit, zero or knock loose. You also get the same three-sided protection for the optic and the same rugged one-handed racking surface at the rear.
How does it compare with the plain Guardian?
The plain Guardian is the guard on its own — same three-sided protection and racking surface, without the integrated sights, for shooters who already have irons or want the simplest unit. The +Six adds the backup sighting solution in the same machined part. The two listings cover different optic footprints, so check yours against the one you are buying.
Is installation straightforward?
It mounts on the Glock MOS optic screws with the hardware supplied, so the optic has to come off and go back on as part of the job. Re-check and confirm your zero afterward rather than assuming it has held, and take the chance to check the backup sight picture at the same time. Torque the optic screws to the figure your optic maker specifies.
