I have two new unopened Surefire 60rnd AR mags that I'd like to trade for 6 black 40 round Pmags or 10 black non-window 30 round Pmags. I paid over $100 each for the Surefire mags. They still sell for over $100 so Im pretty sure this is a really good deal for someone. PM me if you are interested. I can meet in NW Portland.
