No idea with the fastmags, but theoretically they should. Especially if they're the .308 variety. I highly doubt the .223 ones will work. I mean, if RS .308 PMags fit...

Condor Brand AK mag pouches (2x1, 2x2 or 2x3 varieties) all work with some modification, if y'all want a cheaper alternative. Just cut the dividing tab inside the pouch out with some scissors and you're golden.

Mind you, you won't be able to run the pouch closed, you'll have to tuck the flap into the pouch itself. It's plenty snug, though.Just don't try to run the mag pouches upside down like a fastmag... It's also real good as a hammershot holster, especially if the arbor rail is cut down.
