RITON OPTICS PICATINNY MOUNT 34MM B/O 0MOA

Description

The Riton Contessa 34mm Picatinny bolt-on mount is designed for shooters who run full-diameter 34mm scopes on Picatinny-railed platforms and want a one-piece solution that eliminates the alignment variables introduced by separate rings. A bolt-on design attaches directly to the rail as a single rigid unit, so the scope tube sits in a fixed, co-witnessed relationship to the bore without relying on the shooter to torque two independent ring halves into agreement with each other during installation.

The mount is set at 0 MOA, meaning the optical axis runs parallel to the bore rather than angled downward toward it. That geometry is the right choice when your scope’s internal elevation travel is sufficient to reach your intended zero without mechanical assistance from the mount itself — common in shorter-range precision work and tactical applications where holdover is managed through the reticle or ballistic turrets rather than through a built-in cant. If you are running a long-range setup where the scope has already burned through most of its upward adjustment getting to a 100-yard zero, a canted mount would be the alternative to consider. Here, 0 MOA keeps the full elevation range available from the center of travel, which is also where most scope manufacturers report their sharpest optical performance.

Riton finishes the Contessa mount in matte black, which the distributor lists alongside a retail price of $379.99. The 34mm tube diameter accommodates the larger main tubes found on many modern precision and hunting scopes, and the Picatinny interface ensures repeatable return-to-zero if the optic needs to come off the rifle and go back on.
