there are two on the EE as we speak.....Or you can buy mine at.......let say......starting at the low,..low price of .....no never mind,I'LL keep it.LOL. As far as machining a regular sks to take ak mags. It can be done and once (not that it helps you) you have an sks d side by side to an sks ,the different is"t that much. Yes the open is a bit wider and the front of the mag entrance has to be machine longer and lower,and the rear has some material to be removed....like I said if you have them side by side the differents are easy to see and make as required.
