Kbk wz. 2002 BIN

The '''Kbk wz. 2002 BIN''' is a bullpup assault rifle of Polish origin and is chambered in the 5.56x45mm NATO calibre. It was an attempt to re-design the well proven Kbs wz. 1996 Beryl into the bullpup design form. It is a functional fully operational platform with a solid provisional wooden stock. The prototype design was used to develop a computer model designated the BIN-21, which would serve as the basis for the development of the kbk wz. 2005 Jantar.
