The RPM 34mm Low Rail Cap Diving Board Flat Dark Earth is a purpose-built optic accessory designed to replace the top half of compatible RPM 34mm rings and cantilever mounts. Once installed, it adds a compact Picatinny-style rail over the scope tube, giving you a secure mounting surface for rail-mounted laser rangefinders or secondary red dot sights while keeping weight and bulk to a minimum.

This low-profile rail cap is ideal for precision rifles already running 34mm scopes that need an additional device close to the optic body without adding unnecessary height. It fits RPM CLR series rings as well as Bravo and Delta cantilever mounts, using the original cap screws for a straightforward swap. The Flat Dark Earth finish blends cleanly with modern rifle builds, and the solid one-piece construction reflects Ruff's Precision Manufacturing focus on practical, shooter-friendly design.
