The Arisaka Defense Aimpoint Micro Mount Mk2 is a patented design engineered for the Aimpoint Micro T1 and T2 optics. It is also compatible with other red dots that share the same footprint, including the Aimpoint H1/H2, Aimpoint Comp M5/M5S, Sig Romeo 4 and 5, Vortex Crossfire, and Holosun HS503/515/530. Available in three heights—1.54″, 1.93″, and 2.26″—this mount offers flexibility for different mounting configurations and sight picture preferences.
The 1.54″ height provides lower 1/3 co-witness capability, allowing standard AR height iron sights to remain visible in the lower 1/3 of the red dot optic lens. At 2.26″ height, the mount aligns with the Unity FAST FTC Magnifier Mount and positions AR height iron sights visible only through the window beneath the optic. This RDM model ships in the 1.93″ height configuration.
