Radian GUARDIAN + SIX™ Combo Optic Guard & Back Up Irons for Walther PDP 2.0

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. Featuring anti-glare, anti-snag and ultra low co-witness design, SIX™ sights lie inconspicuously in wait until you need to deploy them. Like a wingman when things aren't going as planned, SIX™ has your six.
