The RMU Mount by Reptilia is a lightweight, slim-line solution manufactured at the request of a DoD customer. The RMU Mounts are idea for lifting a variety of optics with fixed height, lower 1/3 co-witness heights such as the EOTech line of holographic optics, Vortex Optics AMG UH-1″ and Sig Optics ROMEO8T to an elevated height which is more ergonomic when using helmet-borne night vision or those who prefer a more upright shooting stance.
