B-18U top mount rail for AKS-74U

The upper RIS mount rail is made entirely of aluinium and is intended for the AKS-74U type replicas. The B-18U rail is an extended version. The rail is mounted on the rear sight of the replica. 

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.
