Reptilia AUS Offset RMR (Left or Right) Black Scope Mount 100-310

The Reptilia AUS Offset RMR Mount is designed as a lightweight, ambidextrous red-dot mounting solution for AR-pattern rifles equipped with Reptilia’s AUS scope mount system. Because it is a passive accessory, it requires no batteries and provides a secure RMR-footprint attachment point for rapid transitions between magnified and unmagnified aiming. The offset mount works with AUS systems built around 30 mm or 34 mm scope tube sizes, each using a 39 mm (≈1.54″) optical centerline height, ensuring consistent alignment with modern AR-height optics. While manufacturer specifications do not list physical dimensions such as height, width, or length for the offset module itself, the mount is known to be extremely lightweight at approximately 30 g (1.06 oz) and is intended for tactical, competition, and general sporting use.
