The Reptilia AUS Mount Extendo Offset is a rugged, lightweight accessory designed to add a secondary red dot optic to the AUS Mount system. Developed for professional end-users who require rapid transitions between magnified and non-magnified optics, this "Extendo" version provides additional forward or rearward spacing to better clear large scope turrets or complex optic configurations. It is precision-machined from billet 7075-T6 aluminum and features a durable MIL-STD Type III hardcoat anodized finish in Black. Its ambidextrous, reversible design allows for mounting on either the left or right side of the main AUS base, maintaining a streamlined, anti-snag profile that is essential for tactical and competitive environments.
