The Reptilia RMU (Rail Mount Ultimate) 9-Slot Mount is a lightweight, professional-grade Picatinny riser developed specifically to meet the ergonomic needs of Department of Defense end-users. By providing a precise 0.625-inch height increase, it elevates fixed-height optics—such as EOTech holographic sights, Vortex AMG UH-1, and Sig Sauer ROMEO8T—to a height that is optimal for shooters using head-borne night vision or those who prefer a more upright shooting posture. The mount is CNC-machined from a single piece of billet 7075-T6 aluminum and features a spring-loaded nitrided steel clamp that sits flush with the body for a snag-free, low-profile design. This 9-slot configuration offers ample rail space for primary optics while maintaining a compact footprint on any MIL-STD-1913 Picatinny rail. Reptilia .625" Height 9 Slot FDE RMU Mount 100-387
