The Reptilia RMU Mount is a lightweight, slim-line solution crafted from billet 7075-T6 aluminum with a Type III hard anodized finish, designed to attach to any M1913 Picatinny rail and provide a precise 0.625-inch height increase for improved ergonomics when using helmet-borne night vision or a taller sight picture. This Mil-Spec 1913 Picatinny rail mount features a spring-loaded nitride steel clamp and mounting bolt that simplify installation and sit flush with the mount body for a low-profile, anti-snag design, helping to preserve a clean platform while lifting a variety of optics to fixed lower 1/3 co-witness heights. Ideal for elevating optics such as the EOTech holographic line, Vortex Optics AMG UH-1, and Sig Optics ROMEO8T, the RMU Mount delivers enhanced sight alignment and repeated zero with minimal bulk, enabling a more upright shooting stance without compromising reliability. Built for durability and field performance, this Reptilia mount combines robust construction with practical versatility for precision-focused shooters who demand secure, repeatable mounting on standard rails.
