If it's a Chinese/Egyptian mutt, it may have a slant cut receiver, in which case you can still find stocks for it, but they are harder to get, and possibly more expensive. The main question is: does you rifle already have the high capacity mag well, or is it a low-capacity? The chances of a high capacity model being slant cut are much less. When you get a chance, take the buttstock off the rifle and look at the back of the receiver. If it makes a 90 turn from the bottom to go up the back of the receiver, you are golden. If it does anything else, it's a slant cut. I personally would probably work on the FCG and the stock set for my compliance parts. Depending on what material you want for the stocks (wood or polymer) you can get all 6 parts for about $120 or so. Pics of the gun with and without the stock attached would be really nice to help figure out what has to be done.
