The ATI MAG AR Schmeisser 5.56 60-round magazine with window is a high-capacity option for shooters who want to push past standard 30-round constraints without sacrificing ergonomics. Built as a partnership between American Tactical and German manufacturer Schmeisser GmbH, this glass-reinforced polymer magazine doubles your round count while staying trim enough for practical use in an AR-15 carbine or pistol platform. Whether you're running .223 Remington or 5.56×45mm, this Gen 2 upgrade brings real utility to the range, training session, or field.

The standout feature here is the patent-pending follower system that makes those extra 30 rounds work without turning your mag into a club. The integrated last-round bolt hold-open tells you exactly when you're dry—no guessing. The clear polymer window lets you see your round count at a glance, so you're never caught off guard about how much ammo you've got left in the stack.

Gen 2 refinements over the original include the new window construction and the improved follower design, addressing real-world feedback from shooters who wanted better visibility and reliability. Built to German specifications and imported for US shooters, this magazine delivers the capacity bump a lot of AR users are looking for without the bulk or feeding issues that sometimes dog ultra-high-capacity designs.
