Цевье (верхняя часть) B-31 Upper Rail for AK series 5KU

B-31 Upper Rail for AK replicas

The upper rail for the B-30 handguard is made entirely of durable and light aluminum, perfectly resembling the Russian original intended for firearms. Rails allow you to improve the functionality and appearance of the classic design of the AK carbine, following the latest trends among the armed forces of the Russian Federation, as well as among civilian users. The rail is mounted to the handguard with 6 screws included in the set.

The 22mm RIS rails allow the replica to be equipped with a whole range of additional accessories - from optical sights and grips to tactical lighting. 

5KU parts fit most AK replicas based on the VFC system (including VFC, Boyi, Cyma) as well as E&L and LCT. We do not guarantee full compatibility, in some cases assembly may require minor modifications and the use of tools on the users end.
