Ruffs Precision Diving Board Rail Cap Features The Ruffs Precision Diving Board Rail Cap is engineered to be compact and lightweight while remaining compatible with as many optic and accessory combinations as possible. This rail cap accessory allows the shooter to add a rail mounted laser rangefinder or a secondary aiming device such as a red dot directly to their existing magnified optic setup. Because it is simply a cap replacement it fits all existing RPM products including every CLR series ring and both Bravo and Delta cantilever mounts without requiring a different base or mount system. The high profile design positions the accessory rail at a usable height above the primary scope s tube. Machined from aluminum and finished in black the Diving Board Rail Cap matches the finish of most RPM mounts and rings for a cohesive factory-like appearance once installed. Sized for a 35mm tube diameter it is a direct fit replacement cap rather than a separate accessory requiring new hardware. The cap screws included with the original RPM product purchase are the exact screws needed to install this accessory so no separate hardware purchase is necessary. For shooters running an RPM mount who want to add a secondary optic without replacing their entire mounting system the Diving Board Rail Cap is a straightforward purpose-built solution.
