Arisaka EXPS Mk2 Mount 2.26″ Black – EOTECH EXPS2/EXPS3 QD Mount

Description

The Arisaka EOTECH EXPS Mount Mk2 is a direct replacement for the factory base on your EOTECH EXPS2 or EXPS3 holographic sight. The OEM mount sets the optic centerline at 1.725 inches, which leaves you stacking a riser to reach a modern 2.26 inch height. This mount handles it all in a single part, so you drop the riser and its extra clamping interface right out of the stack. Less hardware, less weight, and one solid interface between your optic and your rail.

That 2.26 inch centerline is the whole point. It keeps your head upright behind the rifle instead of mashing your cheek into the stock, which helps with faster target pickup, a wider field of view, and plenty of room for a helmet, mask, or ear pro. If you run a magnifier, the 2.26 inch version lines right up with the Arisaka 2.26 inch Magnifier and the Unity FAST FTC, so your setup stays co-witnessed and clean.

What the Arisaka Mk2 Mount Is Built From

Each mount is CNC machined from 7075-T651 aluminum, the tough stuff you want under a hard-use optic, and finished in MIL-A-8625 Type III hard coat black anodizing. The QD function of the factory mount carries over here, since the Mk2 ships with an ADM quick-detach lever for fast on and off without losing your zero point of return. At the 2.26 inch height it comes in at 2.8 ounces, roughly eight tenths of an ounce over the OEM mount, which is a fair trade for ditching a separate riser. It's made in the USA and is patent pending.

Fitment Notes for the EXPS Mk2 Mount

This one is specific, so check your sight before ordering. The Mk2 fits all reticle variants of the EXPS3 and EXPS2, including the EXPS3-0, EXPS3-1, EXPS3-2, and EXPS3-DCR. It does not fit the EXPS3 HD, XPS3, XPS2, 518, 558, 552, or 512. As with any base swap, plan to re-zero after installation, but nothing about the sight itself gets modified.
