American Tactical has partnered with German arms manufacturer Schmeisser GmbH to exclusively import and distribute the Schmeisser S60 60 round AR-15 magazine. Made from glass-reinforced polymer, this patent-pending magazine features a unique follower system that allows for double capacity from a normal AR magazine without being bulky or cumbersome. Designed to shoot both .223 REM & 5.56x45mm, the Schmeisser S60 will give you an instant capacity upgrade over the standard AR magazine.
