The Radian Weapons Guardian Optic Guard (brand part number G1001) is a machined 7075 aluminum housing built to protect a Trijicon RMR-footprint red dot mounted on a Glock MOS slide, guarding the optic from top, front, and side impacts without blocking the sight picture. Radian hard-anodizes the guard for a durable, corrosion-resistant finish and secures it with the same STUD-LOK threaded stud-and-nut interface used across the Guardian line, giving longer thread engagement, greater hold-down power, and more shear resistance than a standard screw-down mount. The TRU-SEAL design eliminates the need for an added sealing plate; pre-installed O-rings on the mounting screws hold the plate watertight against the slide, sealing out moisture and preventing corrosion in the mounting threads.
