I now only own one 30 count mag. The 20's and 10's are SO much easier to work with. I like having a couple of 10's for sighting in when I goof around with trying yet a different optic on the rail. The 20's should really just be standard issue. Mine are all steel though. No idea on the Tapco or any other one. Magpul really needs to dip into the AK world.
