RPM 34mm Low Rail Cap Diving Board Optic Mount FDE

Thirty four millimeter tubes show up on precision scopes with long elevation travel, and those are exactly the rifles that end up carrying a rangefinder. This cap replaces the top half of a 34mm RPM ring and adds a Picatinny rail across the tube for that kind of device.

The low rail height keeps the accessory tucked close to the scope body, which is the version to pick when clearance is not the problem. FDE finish. Fitment covers RPM’s CLR series rings along with the Bravo and Delta cantilever mounts. Swapping the cap means the ring tops come off, so recheck scope level and cap torque when you put the rifle back together.
