ATI Schmeisser AR-15 5.56 / .223 60-Round Windowed Magazine

American Tactical Imports (ATIA(R)) 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 the capacity of a normal AR magazine without being bulky or cumbersome. Designed to shoot both .223 REM and 5.56x45MM, the Schmeisser S60 will give you an instant capacity upgrade over the standard AR mag at an affordable price for your AR Carbine or Pistol. The Schmeisser S60 was built specifically for .223 Remington or 5.56x45mm ammo only.Note: Due to inconsistencies with different brands, Schmeisser does not recommend using 300 Blackout with this magazine. Failure for the magazine to operate with 300 Blackout is not covered by American Tactical's Limited Lifetime Warranty. The Schmeisser S60 has a very powerful high-tension spring. Please use caution if disassembling the magazine for maintenance.
