Magpul PMAG 30 AR 300 B (300 Blackout) GEN M3 30 Round

  • If you've made the switch to 300 Blackout or built your Blackout rifle from the ground up, you know how great of a round this is. Part of the allure of 300 Blackout ammo is that you only need to change out the barrel and muzzle brake on your AR-15 and you are ready to go. But there is actually one more step - you need some Magpul PMAGs that were designed for the Blackout round.

    The PMAG 30 AR 300 B Gen M3 magazine has Optimized internal geometry, specifically designed for the wide variety of 300 Blackout ammunition on the market. In addition to the performance benefits this design provides, these magazines also add an additional layer of safety. That's because "the PMAG 30 AR 300 B’s distinct rib design and smoother upper-half texture provides the shooter a distinct visual and tactile difference from any other PMAG". So you don't have to risk accidentally loading 300 Blackout ammo into one of your .223/5.56 chambered rifles.
