If you are asking can you put a 6POS stock on a 4POS tube...yes, it will probably be a little bit looser tho.
Im not versed with the milspec vs commercial jargon, but there is a difference in diameter. Since both parts are from Bushie they probably match.
Assuming the stock slides on the tube, just it should work just fine :D (correct me if Im wrong..I know AKs not ARs)
