Introducing the 1.70 inches bore height AUS mount for 34mm diameter magnified optics, developed by Reptilia. This mount is the culmination of a two-year development program driven by feedback from end user groups. Similar to our dot mount line, the AUS mount securely attaches to any M1913 picatinny rail using our anti-snag, spring-loaded nitrided steel clamp and custom bolt mounting system. Adjustment can be made with a T-25 Torx or flat blade driver to achieve a flush fit with the mount body, ensuring a low-profile, streamlined design. Constructed 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 robustness and longevity. Like our dot mount line, it meets high standards of durability and precision. The AUS mount is fully compatible with all our existing 34mm ROF line products, maintaining Reptilia's commitment to quality and innovation in firearm accessories.
