I have a new, unused, still in the box Beta C-Mag that I would like to swap for quality G.I. spec M14 magazines (no Korean, Chinese, or aftermarket Promag :thumbdown: ). My mag has the black rear cover, black pouch, personal loader, tech manual, graphite, just as it comes from Beta. I would like to get five M14 magazines in exchange, we each pay our own shipping. Thanks for looking!
