This is a complete WBP AKM rear sight block with the Polish coat of arms specially designed for the Beryl rail system. It is identical to our WBP 7.62x39 rear sight block, but with the addition of the Beryl Rail notch cuts on the back which are neccessary for mountin a Beryl Rail. This rear sight block and Beryl Rear Trunnion are both needed in order to accept the rail mount.
