Introducing the 1.70 inches bore height AUS mount for 30mm diameter magnified optics, crafted by Reptilia. Developed over a rigorous 2 years program in response to user feedback, the AUS mount combines advanced features for optimal performance. Similar to our dot mount series, the AUS mount securely attaches to any M1913 picatinny rail using a spring-loaded nitrided steel clamp and custom bolt system. It can be effortlessly tightened with a T-25 Torx or flat blade driver, ensuring a flush, low-profile design. Machined from a single billet of 7075-T6 aluminum, it features a MIL-STD Type III, class 2 hard anodize coating for durability. The AUS mount is fully compatible with our existing 30mm ROF line, offering reliability and precision for your magnified optics needs.
