Yes, it is a Russian automatic rifle.
An AK is an assault rifle, either an AK-47 or an AK-74.
AK-74 is an assault rifle developed by the Soviet Union in the '70s, which is refined version of AK-47. A different gun, the AK-74u ("u" being short for "Ukorochenniy," the Russian word for "shortened") is a submachine gun that was adopted into service in 1979.
The AK74 assault rifle is made in the Izhmash weapons plant in Izhevsk, Russia.
Yes. The AK-74 is a 5.5mm assault rifle developed by the Soviet Union in the 1970s. Like the AK-47, it is named from the original manufacturer (Avtomat Kalashnikova, or Automatic Kalashnikov) and the year it entered production (1974). It was also designed as an upgrade from the AK-47 and AKM by Mikhail Kalashnikov himself.
AK-47 is an assault rifle with larger rounds, excellent range, medium firing rate and fairly accurate; the AK-74u is an SMG (sub machine gun) that is really a smaller version of the AK-74 assault rifle, and has a high to medium fire rate, adequate range, and usually not used for accuracy.
The main rifle currently used by the Russian Army is the AK-74M. It is a modernized version of the AK-74, chambered for the 5.45x39mm cartridge. It is known for its reliability, durability, and ease of use, and has been the standard issue rifle for the Russian military since the 1970s.
Bulgaria's been manufacturing the AK since the 1950s, but the AK-74 doesn't show in their inventory - although Wikipedia lists the AR-M1 as both a 7.62x39 AKM derivative and a 5.45x39 AK-74 derivative, the AR-M1 is a 7.62x39 rifle - 5.56x45 variants are available, but the Arsenal products page does not show any products in 5.45x39.

You want a pre-ban rifle for $800 or less? Hate to break it to you, but it's not going to happen, least of all when it comes to pre-1989 imported rifles. For that price, your options will either be the Saiga or the AK-74 types made by Century Arms.
The proper answer is"never". The Russian rifle was called simply the AK when it was the milled receiver model, then became the AKM with the switch to the stamped steel receiver, and AK-74 with the switch to the 5.45 caliber. AK-47 is a name created by the Western writers. The AK was officially adopted by the Soviet Army in late 1949.
