American Defense RMSc 45 Degree Offset QD Mount

The American Defense TR offset mount positions an RMSc-footprint optic at a 45-degree angle. It uses quick-detach attachment and a black anodized finish in a compact offset configuration. The angled layout clearly separates this model from the upright co-witness and lower-one-third TR mounts.

A 45-degree offset changes the orientation of the optic rather than simply changing its height. The RMSc footprint remains the compatibility standard, so the sight still needs to match that interface. Quick-detach hardware lets the complete offset sight-and-mount assembly come off the rail together.

This model is intended for an RMSc-pattern sight used in an offset position instead of directly over the top rail. It is the TR option to consider when angle matters more than co-witness or lower-one-third height. For other offset and upright red-dot bases, browse optics and rangefinders.
