Ruffs Precision Rail Cap Diving Board Features The Ruffs Precision Rail Cap Diving Board allows shooters to add a rail mounted laser rangefinder or a secondary aiming device such as a red dot directly to their existing magnified riflescope setup. Designed to work with the 34mm tube diameter standard this cap replacement fits all existing RPM products including the CLR series rings and every Bravo and Delta cantilever mount already in the field. Because it is a simple cap swap installation requires only the cap screws already included with the original CLR ring or cantilever purchase with no additional hardware to source. This approach keeps the overall mounting system compact and lightweight while still expanding what a shooter can run on top of their primary optic. Machined from aluminum and finished in Flat Dark Earth the Rail Cap Diving Board matches the color scheme of many modern precision rifle builds while keeping weight to a minimal 0.12 pounds. At 4.9 inches long and 2.6 inches wide with a low profile height the rail cap adds a usable mounting deck without unnecessarily raising the shooter s overall optic height. Ruffs Precision Manufacturing designs its products to be compatible with as many optic and accessory combinations as possible and this rail cap reflects that philosophy by extending the usefulness of mounts shooters already own. For precision rifle shooters who want to add a rangefinder or offset red dot without replacing their entire mounting system this rail cap is a practical low cost solution.
