Apparently, mag mods are needed as well, and will not work with stripper clips.
Pls read the whole thread (this one), and the one on sksboards.
Won't work with stripper clips.
He's saying cost will be $190-225, so yeah, by the time you buy the adapter and a good amount of XCR pistol mags, you could buy two more SKS.
Then you have four mods to do on each of the mags.
If you want to drop your mags with the bolt closed, you must also mod your bolt (as always, this isn't specific to this mag adapter).
Seems like a lot of $$$ (compared to initial rifle price) and a bit of work, but how else do you get legal 10 round detachables in an SKS (side benefit: no duckbills)?
As far as modifying the magazines... wasn't there a thread about AIA mags being used in M14s?
Isn't the originally designed and manufactured purpose for the mag the only thing that matters?
Just going off the top of my head here, but I believe there were some good posts from Questar about this, in that AIA mag thread.

Check out some of the posts by Questar, specifically #71, #84 and #86. I have no idea if there have been changes since mid-2010 when he made these posts, but it seems to suggest we'd be alright doing some mods to the mags. At least that's the way I understand what he was saying.
