Its a double stack so it holds a lot more than a single stack.
I got it used off a guy who added it with an AK. Said he took it from his masada and was only running hicaps.
I am not sure why they say "Not compatible with AK type AEGs"
Works like a dream in a dboys. AK
-Holds a lot
-Holds what it says ( I counted out 162 bbs)
-Easy to maintain
-May Not work in all AKs (I only tested in a dboys)
-Price maybe. Its a little bit more than other mags. Idk. Get this one if you want to be sure that it will work in your masada.
