Yeah it is an AK-47, there are dozens of different versions of the AK. This one is built in Romania (ROMARM). The material and color of the stock, foregrip, and pistol group vary even more than the manufacturer.
For example, I just recently purchase new wood furnishing for mine, replacing the short wooden "assault" stock, standard, to most european manufactured wood furnished AKs, with a longer stock. The wood is mehogony. No more composite grip. No heavy laquer, nice wood. The look of the gun changes a bit and looks more refined even though the stamped metal still says "cheap".
The gun also has a side mount rail (since you cannot affix a standard rail to the stamped metal receiver housing). I purchased at Knob Creek this past year a Weaver Rail kit that mounts to the Russian bracket and allows just about any site system to be installed. The rail mounts tightly to the side rails and bends over the top of the receiver housing for typical scope placement. I just mail ordered a TASCO red dot (cheap but reliable) to finish it off.
To get back onto topic though, it is an AK, not an SKS. THe SKS does not have a pistol grip, no large capacity mag (unless heavily modified), a different receiver, and a single piece wood furnishing that runs from the butt of the rifle to the foregrip. THere are some similarities such as the gas recoil tube that runs along the top of the barrel as well as the the top foregrip.
This is of course completely confused by custom kits that allow you to mount say a Dragunov stock to the rest fo the gun, or different models produced by (older) East Germany or (new) China's Norinco.
Hope that helps!
Cheers!
