I'm with Triad. The KVAR US made AK stocks are great. There is a potential problem with the MAK 90 though. Some MAK 90s had the rear end of the receiver cut off at an angle while others were left straight. The end of the receiver is covered by the thumbhole stock and the only way to tell is to remove the stock. If your rifle has the square rear end, the KVAR synthtic stocks will work. If it has the angle cut, they will not. If you have an angle cut receiver or prefer a wooden stock set, try Ironwood:

Ironwood makes solid and laminated stocks for all kinds of AKs including MAKs, both straight and angle cut.
As Triad pointed out, to legally use one of the above stock sets, you will have reduce the foreign parts count in your rifle to 10 or less. This is done, of course, by substituting US made parts. If the rifle has a stamped receiver and a muzzle device, you will need 6 US parts. If it has no muzzle device, 5 will do. If the rifle has a milled receiver, the count would be 5 and 4. This is because the stamped guns have a seperate barrel trunnion which is another foreign part to count. The milled guns have no seperate trunnion.
A US stock set counts as three US parts; the stock, the pistol grip and the handguards (both of which together count as 1). If you need 6, as US trigger group will count for the other three required. If you only need 5, you may want to try US mag followers and floorplates. Just make sure that ALL of the mags that will be used with the rifle have them.
