The RPM 30mm High Rail Cap Diving Board Flat Dark Earth from Rubicon Precision Manufacturing is a purpose-built optic accessory that replaces the standard cap on compatible RPM rings and cantilever mounts. Machined to be compact and lightweight, it adds a rigid Picatinny-style rail section above your scope tube for mounting a laser rangefinder or secondary red dot sight without adding another clamp to the rifle.

This 30mm high rail cap is ideal when you need extra clearance over the elevation turret or scope housing, keeping accessories centered over the bore for balanced handling. It integrates seamlessly with CLR series rings and all Bravo and Delta cantilevers, using the original cap screws for straightforward installation. The Flat Dark Earth finish blends cleanly with modern rifle builds while reflecting the precise machining and thoughtful design Rubicon Precision Manufacturing is known for.
