300 Blackout is a rifle cartridge designed for AR-15 platforms, offering superior performance in short-barreled and suppressed firearms. While not a manufacturer, many firearms companies produce 300 Blackout-specific parts, including barrels, upper receivers, bolt carrier groups, magazines, and complete rifles or pistols. These components are popular among shooters and builders seeking versatile, hard-hitting options for hunting, home defense, and tactical applications.
