Arisaka Defense Aimpoint Mount MK2

The Arisaka Aimpoint Mount Mk2 series is a precision-machined mounting solution for Aimpoint red dot optics. Built from 7075-T651 aluminum and finished with MIL-A-8625 Type III hard coat black anodizing, these mounts are made in the USA and designed for hard professional use.

Features

Mounts are available in 1.54" (39.1 mm), 1.93" (49.0 mm), and 2.26" (57.4 mm) heights. The 1.54" height provides lower 1/3 co-witness with standard AR-height iron sights. The 2.26" height aligns with the Unity FAST FTC Magnifier Mount. The 1.93" and 2.26" versions include an integrated accessory interface compatible with upcoming Arisaka accessories such as the Extendo mounting platform.

All mounts are 1.98" (50.3 mm) long and attach to standard Picatinny rails. Each mount includes the required mounting hardware.
