Introducing the 1.93 inches bore height AUS mount for 30mm diameter magnified optics, from Reptilia. Developed over a 2 years period based on extensive end-user feedback, the AUS mount sets a new standard in precision and reliability. Similar to our dot mount line, the AUS mount securely attaches to any M1913 picatinny rail using a spring-loaded nitrided steel clamp and custom bolt mounting system. This innovative design allows for easy tightening with either a T-25 Torx or flat blade driver, ensuring a flush fit for 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 exceptional durability and resistance to wear.
