The '''80.002''' was a combined [[assault rifle]] and [[grenade launcher]] prototype based on the [[AK-74]] platform. The weapon was developed at [[TsNIITochMash]] by Yu.V. Minaev, V.I. Chelikin, and G.A. Yanov between 1975 and 1979. The main difference from the Kalashnikov is the presence of two adjacent barrels of 5.45 mm and 12.7 mm respectively.<ref>http://militaryclub.narod.ru/war/pers.htm</ref> The thickness of the [[Receiver (firearms)|receiver]] was double that of an AK-74. The 80.002 was not accepted for service.<ref name="Monetchikov">{{cite book|last=Monetchikov|first=Sergei|script-title=ru:История русского автомата|trans_title=The History of Russian Assault Rifle|year=2005|pages=187–188|publisher=[[Military Historical Museum of Artillery, Engineers and Signal Corps]]|location=St. Petersburg|isbn=5-98655-006-4|language=Russian}}</ref>
