Introducing the 1.93 inches bore height AUS mount for 30mm diameter magnified optics, by Reptilia. Developed over a 2 years period in response to user feedback, the AUS mount is designed for precision and reliability. Similar to our dot mount series, it securely attaches to any M1913 picatinny rail using an anti-snag spring-loaded nitrided steel clamp and custom bolt system. This system allows for flush tightening with a T-25 Torx or flat blade driver, ensuring a low-profile, streamlined appearance. 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 enhanced durability and resilience.
