The RPM 35mm High Rail Cap Diving Board Black transforms your existing RPM scope mount into a versatile Picatinny platform for add-on optics and accessories. Precision machined from durable aluminum, this high-cut rail cap is designed specifically for 35mm scope tubes and replaces the factory cap on CLR series rings and Bravo or Delta cantilevers without altering your primary optic setup.

This accessory is ideal for shooters who want to mount a rail‑based laser rangefinder or secondary red dot closer to their line of sight while keeping weight centered over the rifle. Installation is straightforward, using the original cap screws and a simple hex key, making it a quick upgrade for long‑range, hunting, or training rifles that benefit from streamlined access to a secondary aiming device. Ruff's Precision Manufacturing is known for compact, lightweight solutions that integrate cleanly with modern optics.
