Ruffs Precision Diving Board Rail Cap Features Ruffs Precision Manufacturing designs its products to be compact and lightweight while staying compatible with as many optic and accessory combinations as possible and this rail cap carries that philosophy forward. Replacing the factory cap on a CLR series ring or a Bravo or Delta cantilever adds a low profile rail section above the primary optic. That rail space gives a shooter room to mount a laser rangefinder or a secondary red dot for faster target transitions and distance confirmation. At a low height and just 8.4 inches long by 3.6 inches wide the cap keeps the added rail real estate from interfering with the primary optic s sight picture. Built from black aluminum the Diving Board Rail Cap weighs only 0.13 pounds adding negligible weight to an already mounted optic setup. Because it is a direct cap replacement installation uses the exact same screws that came with the original RPM ring or cantilever purchase so no separate hardware is needed. This simple swap lets a shooter upgrade an existing CLR Bravo or Delta mount into a dual optic platform without replacing the whole mounting system. For shooters already running RPM products who want to add a secondary aiming device this rail cap is a straightforward purpose built solution.
