Zenitco B-5U Picatinny Riser Mount - See-Through Optic Passthrough (QD)

The Zenitco B-5U is a Picatinny-to-Picatinny riser adapter that creates an optical channel underneath, preserving your view of the mechanical (iron) sight line. It lets you mount additional devices on a Picatinny rail without blocking the iron sights - ideal for co-witnessing an optic with backup irons.

It installs on any Picatinny rail via a quick-detach lever with an adjustable clamp, so you get a repeatable, wobble-free mount that can be tuned to remove any play.
