importing guns into the states is not simple. there are specific rules the batfe has to enforce thanks to our criminals in congress. for example full ak47 cannot be imported in a traditiional akformat with reciever. thats why saiga imports ak47 with sporter stocks. ak47's like century and aim use some parts including receiver made in the US everything else is foreign.
bolt guns some other semi auto can be imported with few changes. its a case by case basis.
