American Tactical Schmeisser S60 M4/AR 60 Round Magazine Gen II ATIM556S60ML

The American Tactical Schmeisser S60 M4/AR 60 Round Magazine Gen II is built for shooters who want serious capacity without sacrificing reliability or handling. Designed to run in standard AR-15 and M4 platforms chambered in .223 Remington and 5.56 NATO, this magazine delivers a full 60 rounds in a compact, efficient form that keeps you shooting longer and reloading less.

At the heart of the S60 Gen II is its unique quad-stacking design. By stacking the cartridges in four columns internally, this magazine achieves high capacity while keeping overall height manageable. That lower profile compared to traditional extended magazines makes prone shooting more comfortable and stable, and it also allows for easier storage in range bags, packs, and pouches. You get the firepower of a drum-style capacity in a format that’s slimmer, lighter, and faster to handle.

The Gen II version adds a window, or witness hole, that lets you quickly check your remaining round count at a glance. That visual confirmation is a major advantage during training, competition, or tactical use, helping you manage reloads and stay aware of your ammo status without breaking focus. It’s a simple feature that adds real-world practicality when every second counts.

Built from durable materials and engineered for consistent feeding, the Schmeisser S60 is designed to handle the high round count it carries. The internal geometry and spring system are tuned to present each round smoothly, reducing the chance of misfeeds and keeping your rifle running clean from the first shot to the last. Whether you’re running high-volume drills, competing, or setting up a defensive rifle, this magazine is made to keep pace.

Despite its impressive capacity, the S60 maintains a balanced feel in the rifle. The quad-stack design helps distribute weight more evenly, so the magazine doesn’t feel overly long or awkward when seated. This improves handling, makes transitions smoother, and keeps the rifle more controllable during extended strings of fire.

For shooters who want maximum on-board ammunition without going to bulky drum magazines, the American Tactical Schmeisser S60 Gen II offers an ideal solution. It combines high capacity, manageable size, and modern features into a magazine that’s built for performance and durability.

From the range to serious training, the S60 Gen II gives you the confidence of knowing you’ve got 60 rounds ready to go, with a quick visual check and a design that supports reliable feeding and practical handling in real-world conditions.
