Im selling 4 USGI 30 round .223 mags I bought at a show in Florida about 2 years ago. I haven't refinished them, so they do show the normal wear in the finish, but shoot and load fine. They are marked on the bottom "Adventure Line Mfg. Co; Parsons, KS USA"
$45 shipped in the lower 48, insurance will be extra at your discretion.
Please make sure it is legal to own these in your state before buying, I am not familiar with all laws and would hate to make a mistake.
