AK 47s cannot be imported.
Parts kits, everything except the receiver can be imported freely, and assembled on American made receivers.
Some few Kalashnikov action weapons like the Saiga can be imported because they are made to look like hunting rifles. (Frankenguns?) Thank you "Slick Willie" Klinton.
If you wish to convert a Saiga to an AK, you have to make it 922 compliant which isn't cheap.
