Introducing the AUS Mount for 36mm diameter magnified optics from Reptilia. The AUS Mount is the result of a focused, two-year design and engineering program dedicated to delivering a rugged, purpose-built solution for precision shooters. The AUS Mount secures to any M1913 Picatinny rail using our anti-snag, spring-loaded nitrided steel clamp and custom bolt system. The bolt can be tightened with either a 5/32� hex or a flat-blade driver, and sits flush with the body of the mount to maintain a low-profile, streamlined footprint. Machined from a single piece of 7075-T6 aluminum billet and finished with a MIL-STD Type III, Class 2 hard-anodized coating, the AUS Mount is engineered for long-term durability in demanding environments.
