The AKS-74UB is one of the rarer Kalashnikov variants, a suppressed short carbine designed for missions requiring minimal noise and visual signature.Derived from the AKS-74U developed by Mikhail T.Kalashnikov in the 1970s, the AKS-74UB was created by a team of engineers at the Research Institute-61 (NII-61, now TsNIITOCHMASH Central Research Institute of Precision Engineering) using the AKS-74U as the base, a mass-produced weapon adapted into a small-production-run specialist tool for clandestine and close-quarters use.
