300 Blackout / Genuine Commercial Brass

300 Blackout was created by Advanced Armament Corporation?along with Remington Defense. ?The objective of developing?this new caliber had to meet?several specific goals. The calibers designers wanted to create a reliable compact .30-cal solution to be used in the AR-15 platform. The round had to?use existing ammo magazines, yet keep the mag’s maximum capacity. Supersonic ammo needed to be similar to the ballistics shared by AK rifles. The 300 Blackout needed to be able to penetrate barriers with high-mass/ heavy projectiles. Most of the 300 Blackout once fired brass available on the market today is actually another caliber brass converted to this cartridge’s specs. Our offered brass is true and genuine factory production that has been once fired in an indoor range. Purchase this brass in confidence knowing that it’s not made in a?garage. This brass is original commercial production to SAAMI specs. ?Our 300 Blackout brass is mixed factory commercial headstamp, once fired from indoor ranges. ? This brass spends little time on the ground,? and cleans up with little effort. ?All the brass is inspected for crushed necks and heavily dinged body wall. ?This provides a low cull rate and gives you a better cost per unit. ?Orders are bagged and shipped in a reinforced USPS Flat Rate Box.
