ARISAKA EXPS MK2 MOUNT 1.93″ FDE

Description

The EOTech EXPS2 and EXPS3 ship with a factory mount that puts the optic centerline at 1.725 inches — a height that works, but leaves shooters who prefer a 1.93-inch cheekweld position reaching for a separate riser. Arisaka’s Mk2 Mount solves this by replacing the OEM mount entirely rather than stacking hardware underneath it. The result is a single, purpose-built unit that achieves the 1.93-inch centerline without the added height, weight, or potential for flex that comes from a riser-plus-factory-mount combination.

That matters practically because every interface between components is a potential point of shift under recoil or during handling. Eliminating the riser removes one of those interfaces, keeping the optic’s zero more consistent across hard use. For shooters running a standard AR stock and preferring a heads-up, chin-welded position rather than a cheeks-to-stock mount, 1.93 inches is the geometry that makes irons and the holographic window work together without forcing an awkward neck angle.

The mount carries a Cerakote finish in Flat Dark Earth, which Arisaka calls out by name — this is not a rattle-can or anodized color coat, but a polymer-ceramic application that resists corrosion and abrasion while adding negligible thickness to mating surfaces. If your EXPS is already wearing FDE, the mount coordinates without mismatching sheen. If it isn’t, the finish still holds up to field conditions regardless of aesthetic preference.

This is a straightforward upgrade for any AR-platform shooter running an EXPS-series sight who wants the 1.93-inch standard without compromise on mounting integrity.
