Available Options
In short: The Zenitco PB-1 is a quick-release Picatinny platform for compatible Vzor sights. Both versions position the sight's optical axis 20 mm above the host rail. Choose the required platform version before ordering: the Base version supports the listed Vzor sights, while Version 2.0 also supports Zhuk-1 and Zhuk-2 bipod mounting.
Choose the platform version
| Version | Documented use | Included screws |
|---|---|---|
| Base | Compatible Vzor sights | Four platform screws |
| Version 2.0 | Compatible Vzor sights plus Zhuk-1 or Zhuk-2 bipod mounting | Four platform screws plus two bipod screws |
Selection checkpoint: both versions support the listed Vzor sights. Choose Version 2.0 only when Zhuk bipod mounting is required. A pair of Zhuk bipods mounted on opposite sides requires two PB-1 Version 2.0 platforms, one for each side.
