Zenitco B-31N Rail
Genuine Zenitco | One-piece CNC-milled D16T aluminum | Picatinny rail over the gas tube | For B-30 / B-30U handguards | 3 colors
In short: the Zenitco B-31N is a one-piece CNC-milled D16T aluminum bracket that forms a Picatinny rail over the barrel and gas block of an AK-pattern carbine. It mounts on the Zenitco B-30 or B-30U handguard with six screws, giving a solid rail platform for optics above the barrel.
Overview
The B-31N is the broad-compatibility member of the B-31 family: it fits all AK-pattern models and the civilian carbines built on that platform, without the 415 mm barrel restriction that limits the plain B-31.
Six M5x9 screws tie it to a B-30 or B-30U handguard, and it lays Picatinny over the barrel and gas block. Milled from D16T aluminum, 95 g, 200 x 47 x 37 mm, in black or desert.

Compatibility: the B-31N mounts onto the Zenitco B-30 and B-30U handguards with six screws, forming a Picatinny rail over the barrel and gas block. It is compatible with AK-pattern carbines and carbines built on the AK-pattern platform. The top Picatinny rail accepts optics, red dot and collimator sights and other aiming devices.
