Genuine Zenitco | Picatinny top rail for the DShK platform
In short: the Zenitco B-51 is a Picatinny top rail for the DShK platform. It mounts optics and accessories above the receiver and comes complete with the install hardware.
Overview
The B-51 gives the DShK platform a full-length Picatinny (1913) top rail, so you can add optics, red dots and accessories where there was no proper mounting surface before. It is machined from aluminum alloy and finished to Zenitco's usual standard.
It installs using the supplied axis pin, drift punch, spacer and washers - everything you need is in the box. Once fitted, it gives you a solid, repeatable mounting platform that holds zero.
