RDM-03 Tactical Riser
RDM-03 is a quick-detach modular tactical riser designed to raise red dot sights to a fixed 57 mm / 2.25″ optical axis, enabling seamless integration of red dots and magnifiers on a single, rigid platform.
Description
The RDM-03 Tactical Riser is a universal quick-detach height compensator developed for AR-15 platforms and modern red dot setups. It provides a fixed 57 mm / 2.25″ optical axis height, improving ergonomics, situational awareness, and compatibility with magnifiers and night vision equipment.
Unlike footprint-specific mounts, RDM-03 is designed as a modular base platform. Its front SMAI interface allows the use of Picatinny rails and direct-mount adapters of various lengths and heights, making it compatible with most red dot sights that use standard factory mounts — while maintaining a consistent optical axis height.
The rear dovetail interface is engineered for high-load accessories such as flip-to-side magnifiers, ensuring precise coaxial alignment and long-term stability under intensive use. Combined with its quick-detach mechanism and rigid construction, RDM-03 forms a highly adaptable and durable aiming platform for professional applications.
