The Arisaka RDM AIMPNT ACRO 2.26" FDE Picatinny mount from Arisaka Defense is designed for the Aimpoint Acro P1 and P2 optics and will also function with other red dots sharing the same footprint, such as the Steiner MPS, offering a versatile platform for quick installation and stable performance on Picatinny rails. Available in 1.54", 1.93", and 2.26" heights, the 2.26" option aligns with the Unity FAST FTC Magnifier Mount, and irons at conventional AR heights are visible through the window beneath the optic only with this height, enabling flexible sighting configurations. The mount weighs 3.2 oz and is CNC machined from 7075-T651 aluminum with MIL-A-8625 Type III hard coat anodizing for rugged durability in field and match environments. Each package includes a single 10-32x1.25" torx socket cap screw, ensuring secure, tool-stable attachment. Crafted in the USA, this optic-specific mount delivers reliable rigidity and precise alignment, enhancing shooting accuracy across tactical, competitive, and hunting applications while maintaining a clean, low-profile appearance on your rifle.
