Zenitco B-31S V2.0 Rail
Genuine Zenitco | One-piece CNC-milled D16T aluminum | 170 mm Picatinny rail over the gas tube | For B-30 / B-30U handguards | 3 colors
In short: the Zenitco B-31S V2.0 is a one-piece CNC-milled D16T aluminum bracket that forms a long 170 mm Picatinny rail over the barrel and gas block of an AK-pattern carbine. It sits low enough to leave the standard iron-sight line of sight clear and mounts on the Zenitco B-30 or B-30U handguard with eight screws.
Overview
The B-31S V2.0 is the upper half that a B-30 or B-30U handguard needs. Eight screws tie it to the lower handguard, and it lays a continuous 170 mm Picatinny rail over the barrel and gas block - profiled low enough that it does not cross the line of the iron sights.
It can also stand in for the B-31L inside a Sport-1 kit, which is the usual way to get a longer top rail on that build. Milled from D16T aluminum, 116 g, 200 x 47 x 37 mm, finished in Black or Desert.
