Arisaka Defense Aimpoint Micro Mount Mk2 1.54″

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 Arisaka Aimpoint Micro Mount Mk2 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.

The 1.93″ and 2.26″ height mounts include an accessory interface that will be compatible with several upcoming Arisaka products.

Weight (including screws):

1.54″ – 3.0 oz

1.93″ – 3.1 oz

2.26″ – 3.2 oz

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 tiny gap between the optic and horizontal surfaces of the mount.

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

Made in the USA.
