The Arisaka Defense RDM is engineered for the Aimpoint Acro P1 and P2 optics and accommodates other red dots that share the same footprint, such as the Steiner MPS. Standing 2.26″ tall, this mount aligns with the Unity FAST FTC Magnifier Mount and permits AR height iron sights to remain visible through the window beneath the optic.
Each mount is CNC machined from 7075-T651 aluminum and finished with MIL-A-8625 Type III hard coat black anodizing. This Flat Dark Earth variant adds Cerakote over the hard coat anodizing to provide tactical aesthetics and enhanced corrosion resistance. The mount ships with screws for optic attachment and requires a T10 Torx driver to secure the Acro to the mount, along with a T27 or IP27 Torx driver to secure the mount to your picatinny rail.
The 2.26″ Arisaka Aimpoint Acro Mount Mk2 delivers a lightweight, robust solution for shooters seeking reliable optic mounting. Patent pending design and USA manufacturing ensure quality and performance you can depend on.
