A buddy of mine got himself a Norinco MAK90 that we took out for the first time awhile back and he loved it. (I am trying my best to turn him into a milsurp nut) But, he doesn't care for the 'thumhole' stock setup. I found a cheap for East German AK furniture using the traditional pistol grip and buttstock setup. It looks like it will go on the MAK 90 with no problems...but have any of y'all tried it? If there is any fitting required, exactly what has to be done? Is it worth the trouble? The EG furniture set costs but $40...
