Arisaka Defense Mk2 EOTECH EXPS Mount 2.26" Black

Arisaka Defense Mk2 EOTECH EXPS Mount 2.26" Black

The Arisaka Defense Mk2 EOTECH EXPS Mount is a purpose-built replacement mounting system for compatible EOTECH EXPS2 and EXPS3 holographic weapon sights. Instead of placing the complete factory-mounted optic on a separate riser, the Arisaka Mk2 replaces the OEM mount itself and positions the optic at a 2.26-inch centerline height.

This integrated approach eliminates the need for a separate 2.26-inch riser while providing the elevated optic position commonly used for a more upright, heads-up shooting posture. The mount is CNC machined from 7075-T651 aluminum and finished in black anodizing.

Direct Replacement for the EOTECH EXPS Factory Mount

The Mk2 is not simply a riser placed underneath the existing EOTECH mounting system. It is designed to completely replace the OEM EXPS mount. This allows a compatible EXPS2 or EXPS3 to reach the desired elevated height without stacking the factory mount on another mounting platform.

2.26" Optic Centerline

A factory EOTECH EXPS mount positions the optic at approximately a 1.725-inch centerline. The Arisaka Mk2 changes the mounting interface to position the optic at a 2.26-inch centerline without requiring a separate riser.

7075-T651 Aluminum Construction

Arisaka machines the Mk2 from 7075-T651 aluminum, providing a strong mounting platform while keeping unnecessary material and weight to a minimum. The mount is finished with a black anodized coating for added surface protection.

EOTECH EXPS2 and EXPS3 Compatibility

The Arisaka Mk2 is designed specifically for EOTECH EXPS2 and EXPS3 holographic sights and is compatible with all reticle variants of those standard models.

Important Compatibility Note: This mount does not fit the EOTECH EXPS3 HD, XPS3, XPS2, 518, 558, 552, or 512. Verify your exact EOTECH model before ordering.

Why Choose the Arisaka Defense Mk2 EXPS Mount?

The Arisaka Defense Mk2 is an excellent option for shooters who want to raise a compatible EOTECH EXPS2 or EXPS3 to a 2.26-inch optic centerline without stacking the factory mount on top of a separate riser. Because the Mk2 replaces the OEM mounting assembly, it creates a more integrated elevated mounting solution.

Its combination of 7075-T651 aluminum construction, direct EXPS compatibility, and 2.26-inch centerline height makes the Mk2 a purpose-built upgrade for compatible EOTECH setups where an elevated optic position is desired.
