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.
Compatibility: designed for RPK-pattern carbines and civilian carbines built on that platform. It installs together with the Zenitco B-20L or B-23L handguard and the DL-3 extension (including within the Sport-5 and Sport-8 kits), fastening with eight screws. The Picatinny rail accepts optics, red dot and collimator sights and other aiming devices.
