The Arisaka Micro Mount Mk2 is designed for Aimpoint Micro T1 and T2 optics and is also compatible with other red dot sights sharing the same footprint, such as the Aimpoint H1/H2, Comp M5/M5S, Sig Romeo 4 and 5, Vortex Crossfire, and Holosun HS503/515/530.
Available Heights:
- 1.93" (4.9 cm)
- Magnifier Mount.
- 2.26" (5.7 cm): AR-type iron sights are visible through the window under the optic only at this height.
Important Notes:
-
Aimpoint Comp M5S and Duty optics are 10 mm (0.393") taller than Comp M5 and Micro T2 models. This affects the effective height:
- A 1.54" mount provides an effective height of 1.93".
- A 1.93" mount provides an effective height of 2.32".
- Standard iron sights will not be visible through the window under the mount in this configuration.
Accessories:
The 1.93" and 2.26" mounts include an interface compatible with upcoming Arisaka products, such as the Extendo mounting platform.
Recommended torque values:
Clamp / Picatinny attachment — 50 in·lb (≈ 5.65 N·m)
Optic → plate (optic screws) — 11.9 in·lb (≈ 1.35 N·m)
Notes:
Use a calibrated torque screwdriver to achieve these exact values.
Common rounding: 50 in·lb ≈ 5.7 N·m (depending on your preferred rounding).
Always follow the optic manufacturer's recommendations if they differ from these values.
Check the torque after the first shooting session.
