NEW from Radian Weapons comes an expensive but interesting new mounting plate system complete with backup iron sight!Only available for Glock MOS for the Trijicon RMR and Holosun EPS or Walther PDP 2.0 with RMR or EPS optics, the Guardian Optic Guard is a mounting plate that connects your optic to the gun. It also has a large window that sits in front of the optic, giving it a large protective face from some drops and all front impacts.Inside the protective window is the ability to add Radian’s new SIX back-up sight, giving you a forward-mounted iron that won’t shift. A combined Guardian + SIX MSRP is $210. The Guardian can be had separately for $180The GUARDIAN + SIX lets operators overcome the inherent shortcomings of traditional one-size-fits-all pistol optic mounting plates. Conventional plates lack comprehensive protection for costly red dot optics and possess inherent vulnerabilities in their mounting hardware, leading to issues such as screws coming loose or shearing off due to applied forces during repeated cycling of the weapon. The GUARDIAN addresses these concerns head-on. Crafted meticulously from 7075 aluminum and durable 17-4 stainless steel, the Radian GUARDIAN presents a solid and dependable mounting solution that prioritizes safeguarding the pistol optic. The proprietary TRU-SEAL™ technology employs innovative o-rings to maintain a watertight seal between the plate and the slide, effectively shielding against moisture infiltration and averting both thread corrosion and the need for an additional sealing plate. One of the key distinguishing features of the GUARDIAN system is its ingenious STUD-LOK™ interface, which offers over double the thread engagement compared to conventional threaded plates. Oversize Torx sleeve nuts with self-locking threads ensure secure attachment. This superior torque-down mechanism pulls the optic rearward against the recoil bosses and solidly against the plate, guaranteeing a rigid mounting interface that surpasses factory-supplied options. This STUD-LOK™ interface allows the plate and guard to be made from high strength lightweight 7075 aluminum, keeping the entire system under the weight of a traditional steel plate.
