In fact there is a civilian version of AK known as Saiga.
It lacks a select fire capability and mostly identical to military AK variants regardess this fact.
There is no ‘assault’ ban in Russia. Everything beyond artillery caliber without full-auto capability is citizen legal. Detachable mags holding more than 10 cartridges aren’t welcome but AFAIK the punishment is simply confiscating that mags or a little fine.
Confusingly, there is no standard designation for a semi-auto AK. You can find "AK-47" applied to both semi-auto and selective fire weapons.
