The Arisaka Defense EXPS Mk2 Mount (Arisaka Defense part no. OM2-EXPS-226) is designed for the EOTech EXPS3 and EXPS2 holographic weapon sights, replacing the OEM mount entirely rather than stacking a riser on top of it. The factory EOTech mount sits at a 1.725-inch centerline, which makes it impossible to reach a 2.26-inch height without extra hardware, so Arisaka machined this mount to hit that 2.26-inch optical centerline directly. Eliminating the need for a separate riser saves weight on the rifle while keeping the mounting interface as simple and low-profile as possible. Finished in black, it’s a clean upgrade for EXPS owners who want a taller cheek-weld height for a night-vision or helmet-compatible setup without stacking parts.
