Same Factory-Built Magazines That Ship With New AR-10s
Brand-new, factory-made, Generation II magazines built by ArmaLite® feature a spot-welded, heavy gauge steel body that won’t distort when fully loaded and a contoured follower designed to ensure exceptionally smooth, reliable feeding. These aren’t converted M14 magazines, but mags purpose-built specifically for the AR-10 Type "B" lowers only - the same mags that come with new rifles. Available in 5-, 10-, 15-, 20- and 25-round capacities to fit a wide range of hunting, competition, and law-enforcement applications. Factory marked floorplate. Will only fit Armalite AR10 rifles, no other makes or models.
