Arisaka Defense Aimpoint Micro Mount Mk2 – 1.54″ Height

The Patent Pending Arisaka Aimpoint Micro Mount Mk2 is designed for the Aimpoint Micro T1 and T2 optics, and will also function with other red dots using the same footprint, including the Aimpoint H1/H2, Aimpoint Comp M5/M5S, Sig Romeo 4 and 5, Vortex Crossfire, and Holosun HS503/515/530.

The 1.54″ micro mount is considered lower 1/3 co-witness, meaning standard AR height iron sights are visible in the lower 1/3 of the red dot optic.

Specs:

• Weight (including screws): 3.0 oz.
• Picatinny clamp: 50 inch-lbs/5.7Nm Torque
• Optic mount: 11.9 inch-lbs/1.35 Nm Torque
• Finish: Type III hard black coat anodized.
• For FDE, Cerakote is applied on top of anodizing.
• Includes all necessary screws and tools for optic attachment.
• Hardware: One 10-32×1.25″ torx socket cap screw, four M3x4mm Torx button head cap screws.
• Made in USA.

Compatibility:

• Aimpoint Micro T1/T2
• Aimpoint H1/H2
• Aimpoint Comp M5/M5S
• Sig Romeo 4/5
• Vortex Crossfire
• Holosun HS503/515/530

Each mount is CNC machined from 6061-T651 aluminum, clamp from 7075-T651 aluminum, and both parts MIL-A-8625 Type III hard coat black anodized. If selected, FDE Cerakote is applied on top of the hard coat anodizing.

Please note: the Aimpoint Comp M5S and Duty are 10mm (0.393″) taller than the Comp M5 and Micro T2, which must be factored into the final height of the optic. On a 1.54″ mount the additional 10mm will result in 1.93″ effective height.

Mounting Details: the Aimpoint Micro mounting interface features three horizontal surfaces and two angled surfaces. The optic is supposed to contact the mount only on the angled surfaces, which wedges it into place and prevents the optic from changing zero under recoil or harsh handling. It is completely normal to see a tiny gap between the optic and horizontal surfaces of the mount.
