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 extensive user feedback. Similar to our dot mount line, the AUS Mount attaches securely to any M1913 picatinny rail using an anti-snag, spring-loaded nitrided steel clamp and a custom bolt mounting system. The bolts can be tightened with either a T-25 Torx or flat blade driver to achieve a flush fit with the mount body, ensuring a low-profile and 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 durability and resilience. Compatible with all existing 34mm ROF line products, the AUS mount upholds Reptilia's commitment to precision and quality in firearm accessories.
