I am kinda wanting to put this stock on an AK, but I am guessing I am going to probably have to machine a few add. parts to make it fit.
You may not have to machine anything; but there is a good possibility that you will have to drill a hole. It looks like it has all the hardware that you will need for it. But I'm no expert, just giving an opinion as someone who modifies many things to make them work.
there are SU stocks that are easy to mod on aks, look around, i dont want to go find it again, i was close to doing it but am short on money.
