Zenitco B-51 Receiver Cover Rail - CNC Aluminum Picatinny Top Rail
Overview
The B-51 is a set of milled D16T aluminum parts finished in black or desert. It fits PK, PKM and PKP large-format platforms.
Installation replaces the standard hinge pin of the receiver cover with the pin supplied in the kit. Nothing is drilled and nothing is permanently altered, so the platform can be returned to its original configuration.
Once mounted, the B-51 forms a Picatinny rail 19 numbered slots long above the receiver cover. The rail sits high enough to carry an optic, a night device or a thermal sight, yet does not block the line of sight through the standard iron sights. A pin punch, spacer, washers, cotter pins and a hex key are supplied so no extra tooling is needed.
