Radian Weapons Guardian+six Combo Optic Guard & Backup Iron Sights for Glock MOS Holosun 407/507 Black

The GUARDIAN is the strongest optic mounting system on the market. TRU-SEAL eliminates the need for an added sealing plate. 0-rings on the mounting screws hold the plate watertight to the slide sealing out moisture eliminating corrosion in the mounting threads. Our STUD-LOK threaded stud/nut mounting interface is the most secure system on the market. This provides much longer thread engagement greater hold down power with increased shear resistance.

SIX back-up sights (BUS) seamlessly integrate into the Guardian Optic Mounting System providing rapid reliable and precise target acquisition in scenarios of red dot optic malfunction.
