The Reptilia AUS Mount Extendo Offset is a specialized accessory for the AUS Mount system, providing a 45-degree offset mounting point for secondary red dot sights. This "Extendo" version is specifically lengthened to push the secondary optic forward, offering better clearance for large windage turrets or bulky primary optics that might otherwise obstruct the shooter's field of view. Precision-machined from 7075-T6 aluminum and finished in a durable Flat Dark Earth hardcoat anodizing, it maintains a low-profile, snag-free design. It is fully reversible, allowing for left- or right-side mounting depending on the user's preference, and is built to the same rigorous standards as Reptilia’s primary optic mounts to ensure a repeatable zero in demanding conditions.
