Introducing the 1.93 inches bore height AUS mount for 30mm diameter magnified optics, from Reptilia. Developed over a rigorous 2 years period based on direct user feedback, the AUS mount represents the pinnacle of precision engineering. Like our renowned dot mount series, the AUS mount securely attaches to any M1913 picatinny rail using an anti-snag, spring-loaded nitrided steel clamp and custom bolt mounting system. This system can be tightened using a T-25 Torx or flat blade driver to achieve a flush fit, ensuring a low-profile, streamlined design. Crafted from a single piece of billet 7075-T6 aluminum, the AUS Mount is finished with MIL-STD Type III, class 2 hard anodize coating for exceptional durability and corrosion resistance, meeting the highest military standards.
