If any gun manufacturer out there thought there was profit to be made in producing an "All American" AK-47, you would have seen it by now.
Not necessarily. Here in ND, we have lots of oil (shale oil, Bakken and Taylor formations) but oil has to be selling more than $70 a barrel to make the drilling and frakking cost effective, i.e., make a profit.
With the AK, and America manufacturer could make them, say for $750 MSRP, but with imports selling south of $500, it's not cost effective. With all of the AK uppers made for AR lowers, I would think the interest is really there, just not profitable - for now.
