In short: the Zenitco B-31L is a one-piece CNC-milled D16T aluminum bracket that forms a Picatinny rail over the barrel and gas block of an AK-pattern carbine. Together with the B-10L handguard and the DL-1 extension it makes up the Zenitco Sport-1 kit, giving a solid platform for optics above the barrel.
Overview
The B-31L is the top rail of the Sport-1 kit. Eight M5x7 screws tie it to the B-10L handguard and the DL-1 extension insert - those three parts together are what Sport-1 is.
It lays Picatinny over the barrel and gas block, and fits the 103, 104, 105, 74M and 74S variants along with civilian carbines built on that platform. Milled from D16T aluminum in black or desert.
