The 80.002 was a combined assault rifle and grenade launcher prototype based on the AK-74. 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.{{Cite web|url=http://militaryclub.narod.ru/war/pers.htm|title = Преспективные пути развития автоматов (штурмовых винтовок)}} The thickness of the receiver was double that of an AK-74. The 80.002 was not accepted for service.{{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}}{{Cite web |last=C |first=Luke |date=2020-08-11 |title=Oh God, He's Done it Again but This Time it's Double Trouble - TFB Reader's Double Barrel AR-15 |url=https://www.thefirearmblog.com/blog/2020/08/11/double-trouble-double-barrel-ar-15/ |access-date=2025-05-23 |website=thefirearmblog.com |language=en}}
