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 EOTechA(R) EXPS and VortexA(R) UH-1, and many other optic choices out on the market.Features:Relief cuts to keep the weight as low as possible.Made in U.S.A.Lifetime warrantySpecifications:Material: 7075 T6 Aluminum/4140 steelFinish: Type III Hard Coat AnodizedCompatibility: Any direct to picatinny mounted optics or accessories
