Ruffs Precision Rail Cap Diving Board Features The Ruffs Precision Rail Cap Diving Board is engineered to be compact and lightweight while staying compatible with as many optic and accessory combinations as possible. Designed as a simple cap replacement it fits any existing RPM CLR series ring or Bravo/Delta cantilever mount without requiring a new base or ring purchase. The cap screws included with the original RPM mount are the exact screws needed for installation which keeps the upgrade straightforward for anyone already running Ruffs Precision hardware. Sized for a 30mm tube at a high ring height this rail cap sits ready to accept a rail mounted laser rangefinder or a secondary red dot sight. Machined from aluminum and finished in Flat Dark Earth the Rail Cap Diving Board matches the rest of a Cerakoted or FDE-finished rifle build for a cohesive look. At just 0.12 lbs the added weight on the rifle is negligible so shooters gain a mounting point for a secondary aiming device without meaningfully changing the balance of the rifle. This diving board style mount positions the auxiliary optic forward and offset from the primary riflescope letting a shooter transition quickly between magnified glass and a fast reflex sight. For anyone running an RPM cantilever or ring set who wants to add a rangefinder or red dot this rail cap is the direct solution.
