The RPM 34mm Low Rail Cap Diving Board Black is a compact, low-profile accessory designed to turn the top of your existing RPM 34mm ring set or cantilever mount into a functional Picatinny rail. Precision machined from 6061-T6 aluminum, this diving board cap keeps secondary optics and accessories centered over your primary scope while maintaining a lightweight footprint and clean lines.

This low rail cap is ideal for mounting a small red dot sight or laser rangefinder directly above a magnified optic, helping maintain rifle balance and a consistent line of sight. It replaces the factory cap on CLR series rings and Bravo/Delta cantilevers using the original screws, making installation straightforward with no extra hardware required. Alignment lugs help minimize cross-threading, reflecting RPM’s focus on practical design and careful craftsmanship.
