RPM 34mm High Rail Cap Diving Board Optic Mount FDE

High rail caps exist because accessories are not all the same size. A larger rangefinder body or a red dot with a taller housing needs the rail lifted, and this cap provides that clearance while keeping the device centered over the scope rather than parked off on the receiver.

This is the 34mm version in FDE. It works with RPM’s CLR series rings and the Bravo and Delta cantilever mounts, so the top cap on an existing setup comes off and this goes on in its place. RPM keeps the part compact and light, which counts on a rifle already carrying a magnified optic plus a second device up top.
