The ARMASPEC ELEV8 Plank Optic Riser offers a secure and precise solution for lifting holographic and optics that are mounted directly on a Picatinny rail with a standard lower 1/3 co-witness mount. It’s Cantilever design helps push the optic out further from the shooter making more room on the upper for magnifiers. It raises the optic to a precise height positioning the optical center line at 2.26 inches above the rail. This aids the shooter in many different areas including shooting passively with Night Vision or shooting with a gas mask. It also helps get the sight in line with the shooters vision speeding up time on target. This elevation provides a solid platform making it convenient to directly attach optics including those designed for lower 1/3 co-witness configurations such as the EOTech EXPS and Vortex UH-1 and many other optic choices out on the market.
