Zenitco B-5 QD Riser Mount - See-Through Picatinny-to-Picatinny Adapter (Quick-Detach V2.0)
Genuine Zenitco | Picatinny-to-Picatinny riser | See-through optical channel | Quick-detach lever (V2.0) | Anodized aluminum
In short: a genuine Zenitco B-5 - a Picatinny-to-Picatinny riser that raises an optic or accessory and forms a see-through optical channel underneath, so you keep a clear view of the mechanical sights. This is the quick-detach V2.0 version with a lever clamp for fast, repeatable mounting. Machined from anodized aluminum; about 61 g. Finished in black.
The B-5 lifts a Picatinny-mounted device to a higher line while leaving an open channel below the top rail. That channel lets you look straight through to co-witness the standard mechanical sights, which is handy when you want an added optic or accessory without losing your backup sight picture. The quick-detach lever locks the mount solidly onto a base Picatinny rail and releases it in seconds for transport or swapping.
A genuine Zenitco factory part machined from aircraft-grade aluminum alloy with a hard-anodized finish; it measures about 80 x 40 x 25 mm and weighs about 61 g. Rated for a working temperature range of -50 to +50 C.
Compatibility Note: Clamps onto any standard Picatinny (MIL-STD-1913) base rail and presents a Picatinny rail on top. This is the V2.0 quick-detach version. Ships with the B-5 mount and a manual.
