Zenitco B-2U Picatinny Rail Adapter
Genuine Zenitco | CNC-milled D16T aluminum | Bazis-to-Picatinny adapter | 75 mm, cam-lock + screw | 3 colors
In short: the Zenitco B-2U is a CNC-milled D16T aluminum adapter that clamps onto a Zenitco Bazis guide rail and forms a long 75 mm Picatinny rail for accessories. It secures with a cam-lock, an M5×9 screw, or both together.
Overview
The B-2U is the long member of the B-2 family at 75 x 20 x 9 mm and 15 g without hardware. It is the one to use when the accessory needs real rail length - a light with a long body, a bipod, a mount that spans several slots.
Two cam clamps and an M5x9 screw are supplied. Milled from D16T aluminum in black or desert.
