Reptilia AUS Optic Mount 39mm Height Short FDE 34mm. Driven by the request of an end user group the AUS Mount is the culmination of a 2 year development program. Like our DOT Mount line the AUS Mount attaches to any M1913 Picatinny rail via our anti-snag spring-loaded nitrided steel clamp and custom bolt mounting system which can be tightened with a T-25 Torx or a flat blade driver to sit flush with the body of the mount for a low-profile streamline design. Also like our DOT Mount line the AUS mount is machined from a single piece of billet 7075-T6 aluminum and is finished with MIL-STD Type III Class 2 hard anodize coating. Like all Reptilia products the AUS Mount is carries a full lifetime warranty against manufacturer defects.
