The Radian Weapons Guardian+Six Optic Mount for Glock MOS slides, Holosun 407C/507C footprint (brand part no. H0001) is built as the strongest optic mounting system on the market. TRU-SEAL construction eliminates the need for an added sealing plate, and O-rings on the mounting screws hold the plate watertight to the slide, sealing out moisture and eliminating corrosion in the mounting threads. Radian’s STUD-LOK threaded stud/nut mounting interface delivers longer thread engagement, greater hold-down power, and increased shear resistance than a typical screw-only mount. Six integrated back-up sights (BUS) seamlessly work into the Guardian system, giving anti-glare, anti-snag, ultra-low co-witness sight acquisition if the red dot ever fails. For Glock MOS owners running a Holosun 407C or 507C, this red dot mount pairs a secure mount with a built-in backup.
