I have a complete genuine Russian ZenitCo rail system for the stamped receiver Izhmash Saiga series of rifle. Unfired and in excellent condition...I had this mocked up on my FIME Group SGL31-68, but I'm changing it back to stock form. This set comprises the B10M modular lower handguard with full Picatinny coverage, the B19 top cover, a Russian Molot handstop vertical grip, and ZenitCo black ladder rail covers (just like the Ergo/MagPul US ones). This setup will accommodate the ZenitCo B33 top cover if you so desire. This setup would normally cost you about $350.00 separately...but it can be yours for $225.00 shipped.
