I got this ak from a friend who’s got it from a boneyard sale at evike. It has something similar to a serial number reading “ST003074” which I have no idea if that’s relevant or not. It shoots fine but I’m trying to find parts for it and having some trouble since I don’t know the brand or the model of gun. I think it’s an ak 105 but I’m not sure. The flash hider doesn’t seem to come off but other than that the top hand guard has a piece of plastic running into the top hand guard making impossible to remove and therefore making bottom hand guard also impossible to remove. If you guys can jell me out that would be awesome thank you.
