The RMU Mount by Reptilia is a lightweight, slim-profile mount developed at the request of a DoD customer. Perfect for elevating optics with fixed or lower 1/3 co-witness heights, such as the EOTech holographic optics, Vortex Optics AMG UH-1 and Sig Optics ROMEO8T , it enhances ergonomics for users with helmet-mounted night vision or those preferring a more upright shooting position.

The spring-loaded nitride steel clamp and mounting bolt make installation easy, while the flush, low-profile design ensures an anti-snag, streamlined setup.
