I was one of those people who paid $275 for those AIA mags. It's a #### load of $$$, but dam worth it. Despite the cost, I'm glad to the have the mag. 10 is way better than 5, and I'm not someone who needs to have 20 mags. One will do espesially if you load with stripper clips. Currently considering getting a spare. Keep you pm box open Dook.
