The Radian Weapons Guardian + SIX combo is an optic guard and back-up iron sight set for full-size Glock MOS pistols with an RMR footprint (Radian Weapons part no. G1501). The Guardian is a 7075 aluminum mount and guard plate that sits over the optic, and the SIX back-up sights integrate into it so iron sights remain if the red dot fails. Radian seals the mount with its TRU-SEAL O-rings, so no separate sealing plate is needed, and secures the optic on STUD-LOK threaded studs. It is aimed at the MOS Glock owner who runs a red dot for carry or duty and wants protection and a built-in backup.

Key Specifications

• This combo is built for full-size Glock MOS pistols, and Radian states it is not compatible with Slimline or Gen6 Glocks.
• The optic footprint is RMR, the pattern this Guardian plate is cut to accept.
• The guard and plate are 7075 aluminum with Type III hard anodizing, for a durable finish.
• The mounting screws are custom machined stainless steel with oversized Torx sockets.
• TRU-SEAL O-rings on the mounting screws hold the plate watertight to the slide, so no added sealing plate is required.
• The optic mounts on STUD-LOK threaded studs with self-locking sleeve nuts, giving longer thread engagement than a screw-only mount.
• The included SIX back-up iron sights are anti-glare, anti-snag and ultra-low co-witness, and they integrate into the guard.
