ATI Schmeisser S60 60-Round AR Magazine .223/5.56

Description

The Schmeisser S60 is built for people who want to squeeze every advantage out of range time and competition. Made in Germany by Schmeisser GmbH and imported exclusively by American Tactical, this magazine holds 60 rounds of 5.56 NATO or .223 Remington while staying thinner than drum magazines, making it easier to carry multiple mags on a plate carrier or chest rig.

How the S60 Achieves Double Capacity

The real innovation here is the dual-spring, dual-follower system that lets the magazine stack rounds in two different configurations. The first 30 or so rounds stack traditionally, then the design shifts to a quad-stack arrangement for the upper portion. This means you're getting genuinely double the ammo without the bulk that comes with most extended magazines. The glass-reinforced polymer body is molded with aggressive texturing on the sides, making it easy to grip and manipulate even under stress.

What You Get With the Windowed Version

This model includes a clear polymer witness window running down the side, so you can see exactly how many rounds remain without having to guess. An orange-colored follower also provides quick visual feedback. The Gen 2 design added a last-round bolt hold-open feature integrated into the follower, which earlier versions struggled with. Now it plays nice with bolt catch devices on pretty much any AR platform.

Loading and Using the S60

One real-world consideration: the magazine has a very strong dual-spring setup that makes manual loading progressively harder as you approach full capacity. Most people find the first 20 rounds load smoothly, but the last 10 get tough. A magazine loader like the MagLula makes this nearly effortless. Once loaded and in the gun, the S60 runs reliably with quality brass ammunition. You're adding about 2 pounds to your rifle when fully loaded, which matters in prone shooting but gives you a stable platform.

Built for Competition and High-Round-Count Sessions

This magazine shines in competition shooting where every reload costs you time, or for anyone who wants maximum rounds on tap without constantly changing mags. Works great for practice sessions where you want to maximize trigger time. Just keep in mind it's designed for 5.56 and .223 only—manufacturer doesn't recommend using it with .300 Blackout due to possible feeding inconsistencies.
