Arisaka Defense Aimpoint Micro MK2 Mount, 2.26

Arisaka Defense Aimpoint Micro MK2 Mount, 2.26″

The Arisaka Aimpoint Micro Mk2 Mount is designed for the Aimpoint Micro T2 and will also function with other red dots using the same footprint.

The Arisaka Aimpoint Micro Mk2 Mount is available in 1.54″, 1.93″, and 2.26″ heights. 1.54″ 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 lens. 2.26″ matches up with the Unity FAST FTC Magnifier Mount. AR height irons sights are visible through the window underneath the optic only with the 2.26″ Aimpoint Micro Mount Mk2.

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. On a 1.93″ mount the additional 10mm will result in 2.32″ effective height. AR height iron sights will not be visible through the window underneath the mount in this configuration.

Weight (including screws):
1.54″ – 2.3 oz
1.93″ – 2.5 oz
2.26″ – 2.6 oz

If you intend to use iron sights that are visible through the window in the mount, they need sit above the mounting rail surface by at least 0.29″ for 1.54″ mounts and 0.32″ for 1.93″/2.26″ mounts.

Each mount is CNC machined from 7075-T651 aluminum and MIL-A-8625 Type III hard coat black anodized. If selected, FDE Cerakote is applied on top of the hard coat anodizing. Includes necessary screws to attach optic to mount.

Recommended torque values:
Picatinny clamp – 50 inch lbs (5.7 Nm)
Optic to mount – 11.9 inch lbs (1.35 Nm)

Additional 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 small gap between the optic and horizontal surfaces of the mount like shown below:

Hardware: One 10-32×1.25″ torx socket cap screw, four M3x4mm Torx button head cap screws.

Made in the USA.
