The Reptilia AUS Offset Mount (brand part no. 100-230) gives AR-platform shooters a fast secondary sighting option for any red dot using the Aimpoint ACRO or Steiner Optics MPS footprint. Built as part of Reptilia’s AUS Mount System, this offset mount bolts to the four integrated mounting locations on the AUS Mount body and can be flipped to either the left or right side to match a shooter’s dominant eye. It is a natural fit for competition shooters and duty carbines running a primary magnified optic who still want a rapid-transition red dot for close targets.

Key Specifications

• Designed for the Aimpoint ACRO and Steiner Optics MPS footprint, so it also fits any MRDS sharing that mounting geometry.
• Functions as a secondary sighting system, letting shooters transition instantly from a magnified optic to a red dot for close-range targets.
• Mounts at 4 integrated locations on the AUS Mount body for flexible positioning.
• Fully reversible so it can be run on the left or right side of the mount to match eye dominance.
• Classified as an offset mount, keeping the primary optic’s sightline clear while adding the secondary dot off-axis.
• Finished in flat dark earth to match FDE-coated rifles and accessories.
