Good evening to you!! No, the American Tactical Imports Schmeisser S60 60rd Black Polymer Detachable Magazine is not designed to reliably function with .300 Blackout ammunition. While it's compatible with .223 Remington and 5.56 NATO, Schmeisser and American Tactical specifically state it is not recommended for .300 Blackout due to potential inconsistencies in operation with different brands of that ammunition. Using .300 Blackout in this magazine could void the warranty. Hope this is helpful. Have a good rest of your weekend.

Hi Thomas and welcome. Unfortunately, no. I have these magazines and 5.56 and .223 will run no issue. They only run the heavier 300 BLK rounds with about 60% reliability. Cheers, stay safe and enjoy!

Hi Thomas, the Schmeisser S60 was built specifically for .223REM or 5.56X45MM ammo only. Schmeisser & American Tactical have done some testing and found that the S60 may not operate with all types of .300 Blackout ammo. 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. Stay safe & have a great day!
