Radian Weapons Guardian+Six Features The Radian Weapons Guardian+Six is built around a TRU-SEAL sealing system that eliminates the need for a separate sealing plate using o-rings on the mounting screws to hold the plate watertight against the slide. This seal keeps moisture out of the mounting threads directly addressing a common source of corrosion and loosened screws on optic-equipped pistols. The STUD-LOK threaded stud and self-locking sleeve nut mounting interface is engineered for far longer thread engagement than typical fasteners delivering greater hold-down power and increased resistance to shear forces under recoil. This combination of sealing and fastening technology makes the Guardian+Six one of the most secure optic mounting platforms available for a Glock MOS slide. Six back-up sights are integrated directly into the Guardian optic mounting system providing a reliable path to rapid precise target acquisition if the red dot optic ever malfunctions. An anti-glare anti-snag and ultra-low co-witness design keeps the sights tucked out of the way during normal use ready to deploy the instant they are needed. Machined from 7075 aluminum with a Type III hard anodized finish and paired with custom stainless steel fasteners featuring oversized Torx sockets the Guardian+Six is built to handle demanding use without failure. The kit includes plate mounting screws TRU-SEAL o-rings and STUD-LOK studs and sleeve nuts giving shooters everything needed for a complete secure installation on a Holosun 507C compatible optic.
