I wouldn't even bother with the Colt mags. You can buy 2 others for the price of one Colt. Just check the feed lips, bottom tabs, butt plate, springs to make sure they're good. The finish? Who cares? They're mags.
I'd also hold off on buying Wolff springs and green followers, and magpulls, and all the rest....sheesh. Save your money for ammo before you turn your rifle into a 50lbs-37mm-Aimpoint-Knight-Surefire-RediMag-TacLatch-TacSling-TacEverything-Bayonet Nose-SHTF neck ornament. Make-up can't really disguise an ugly chick, and UrbanTacOpsSOFBlackEagleSAS Consumer Supplies can't really disguise a lousy shooter.
Hey, by the way, WELCOME! And please stay away from the "Reverse Discrimination Why Do Blacks, Gays, Illegals, and Jews Get Special Treatment At The Expense Of The Oppressed White Men" threads. They kinda make you think twice about some of our fellow gun owners.
