There are a number of magazines on the market that fill a unique niche of users who have AR-style rifles chambered in the popular 7.62x39 cartridge. For those rifle owners, the Maglula AR 7.62x39 Lula Loader & Unloader is built to work with specific magazines common to that platform. In particular, the Maglula AR 7.62x39 Lula Loader & Unloader functions with AR Stoner, ASC, C Products, D&H, 10-round Franklin Armory and Pro-Mag magazines. The company warns that, due to the lack of an anti-tilt follower in these magazines, loading the first three and last three rounds in the magazine may be challenging. However, the other rounds will load without issue. Works with 7.62x39 AR magazines only Saves thumbs from soreness of loading Reduces wear on magazine feed lips Compact, lightweight design for easy transport To cope with the thin sheet metal used in these magazines, the Maglula AR 7.62x39 Lula Loader & Unloader also features a metal magazine catch to resist pressure from the magazine edge during use. This may leave a mark on the magazine body, so the company warns users to avoid use of the Lula if these marks are an issue.
