DescriptionThe Patent Pending Arisaka Aimpoint Micro Mount 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 5, Vortex Crossfire, and Holosun HS503/515/530.The low profile, minimalist design and 7075-T6 aluminum construction withMIL-A-8625 Type IIIhard coat anodizingensures strength and durability.The Arisaka Aimpoint Micro Mount is available in 1.70″ and 1.93″ heights, and with black or clear (tan) hard coat anodizing. Why do we offer 1.70″? Many people find this height provides the perfect balance between heads up orientation and enough cheekweld to be consistent, which is evident in the rising popularity of 1.70″ scope mounts.Please note: the Aimpoint Comp M5S is 10mm taller than the regular Comp M5, which must be factored into the final height of the optic (on a 1.70″ mount the additional 10mm would make it ~2.09″ final height).Weight (including screws):1.70″ – 3.0 oz1.93″ – 3.1 ozEach mount is CNC machined from 7075-T6aluminum andMIL-A-8625 Type IIIhard coat black or clear anodized (clear hard coat with 7075 provides the tan color). Anodizing colors may slightly vary from part to part and batch to batch, and is completely normal.Includes all necessary screws and tools 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.Made in the USA.
