The RPM 35mm Low Rail Cap Diving Board Black is a purpose-built accessory that turns the top half of your RPM scope ring into a compact mounting solution. Machined from aluminum with a short Picatinny-style rail, it provides a stable platform for a laser rangefinder or small red dot directly over your optic, keeping added gear centered and streamlined.

This low-height 35mm cap is designed specifically to replace the factory cap on RPM CLR series rings and Bravo/Delta cantilever mounts, using the original cap screws for a clean, secure installation. Ideal for precision rifle shooters who want to add a secondary sighting system or rangefinding capability without extra clamps or side-mounted rails, it supports range use, training, and hunting setups where balance and weight matter. The thoughtful design reflects Ruff's Precision Manufacturing’s focus on practical innovation and careful craftsmanship.
