As my inventory of AR platform rifles has grown over the years, I have found it more and more difficult to keep the magazines for them sorted out and easy to access. Finally got tired of shuffling them around and built two holders, one small, one a bit larger. I have attached them to the wall above my gun safe, and, while they ain't very pretty, they're in a closet, out of view, and function quite well to spread some order on the magazine chaos!
