In short: the Zenitco B-31RPK is a CNC-milled D16T aluminum upper bracket that forms a Picatinny rail over the gas tube and barrel of an RPK-pattern carbine. It sits high enough to leave the standard iron-sight line of sight clear, giving a solid platform for optics above the barrel.
Overview
The B-31RPK is the gas tube rail for RPK-pattern builds and the civilian carbines based on them. It works together with the B-20L, B-23L and DL-3 brackets, including inside the Sport-5 and Sport-8 kits.
Six M5x7 screws hold it. The Picatinny it forms runs over the gas tube and barrel, and is profiled so it does not cross the line of the standard mechanical sights. Milled from D16T aluminum in black or desert.
