The Kastle Fortress EXPS-226 riser raises an EOTECH EXPS holographic sight to a 2.26" optical centerline, a position the maker says improves target acquisition and shooting ergonomics. It uses an M1913 Picatinny riser platform, so any Picatinny rail becomes an elevated mounting surface for your optic. It is built to fit the EOTECH EXPS, so you are not adapting a generic mount to the sight.

The riser is made from 7075-T651 aluminum and carries a Type III MIL SPEC hardcoat anodized finish. It attaches with Titanium K-Clamp mounting technology, which is how the riser locks onto your rail. This version comes in Flat Dark Earth, one of five colors Kastle offers for the EXPS-226. Kastle makes it 100% in the U.S.A.
