EXTENDO – Offset for AUS™ Mount

More clearance. Same system.

The Reptilia EXTENDO is a purpose-built extension designed to work with all AUS™ Offset Mounts, increasing standoff to accommodate optics with larger windage turrets. By pushing the offset mount outward by 0.4 inches, the EXTENDO provides additional clearance without compromising alignment, stability, or speed of engagement.

Engineered as part of the AUS™ Mount System, the EXTENDO maintains the same low-profile, modular design while solving a critical fitment issue encountered with certain LPVOs and magnified optics. Whether running aggressive turret designs or larger-format glass, the EXTENDO™ ensures your offset red dot remains fully usable and unobstructed.

Installation is straightforward, utilizing the included 0.875” mounting screws to securely interface between the AUS™ Mount body and any compatible Reptilia offset mount. The result is a clean, rigid extension that integrates seamlessly into your existing setup.

Machined from 7075-T6 aluminum and weighing just 6 grams, the EXTENDO adds minimal mass while delivering maximum utility. Finished with MIL-STD Type III hardcoat anodizing, it is built for durability under hard use.

Like all Reptilia products, it is 100% made in the USA and backed by a lifetime warranty against manufacturer defects.

Note: Designed to improve compatibility with optics that may otherwise occlude the offset sight picture due to larger windage turret profiles.
