Arisaka Defense Mk2 Mount Features The Arisaka Defense Mk2 Mount completely replaces the factory EOTech mount rather than stacking a riser on top of it which saves weight and simplifies the optic s mounting system. Because the OEM mount sits at a 1.725 inch centerline height reaching a true 2.26 inch optic height previously required an added riser a solution that adds bulk and introduces another point of potential movement. This mount is compatible with all reticle variants of the EXPS3 and EXPS2 giving shooters running either model a drop in upgrade path. It will not fit the EXPS3 HD XPS3 XPS2 518 558 552 or 512 models so fitment should be confirmed before installation. Machined from 7075-T651 aluminum the Mk2 Mount is built to the same strength standards as other Arisaka Defense mounting products holding zero through repeated use. The Flat Dark Earth Cerakote finish matches common rifle builds while adding corrosion resistance to the mount s surface. At 2.26 inches of optic height the mount is designed to properly align with elevated iron sights or a standard AR-15 sight picture. The Arisaka Defense Mk2 Mount gives EOTech EXPS owners a cleaner lighter way to achieve correct optic height on their rifle.
