I bought 4 Brownell's 30 rnd mags about a day before they disappeared for 15 or $16 each. I wasn't sure I'd ever see them as when just for kicks I checked the next day and there were NONE available. Let your conscious be your judge on a price, be fair but I wouldn't loose sleep if making some money off them. I wouldn't go over $30 each for even a distant friend. Now a stranger though Craig's list then what ever they are willing to give. Of course I don't have enough to warrant selling any. course now I'm hoping to get more .223 ammo, got some back ordered and don't know what to expect. Only had a small stash of them.
