Important Usage Notes & Compatibility

  • Do NOT rely on this mag for .300 Blackout — Schmeisser/ATI recommend not using .300 BLK in the S60 due to inconsistent functioning with certain 300 BLK loads; failures with .300 BLK are not covered by American Tactical’s limited lifetime warranty. Use only .223 Rem or 5.56×45mm unless you accept potential function issues. An Official Journal Of The NRA+1
