The .300 AAC Blackout was developed by Advanced Armament Corporation in cooperation with Remington and was submitted to SAAMI in 2011 as a standardized .30-caliber cartridge for the AR-15 platform. Its design was influenced by the earlier .300 Whisper, with the Blackout developed to provide both effective supersonic performance and heavy subsonic capability while maintaining compatibility with standard AR-15 magazines and bolt components. Today, 300 Blackout ammunition is widely used for recreational shooting, hunting, and suppressed shooting, with the availability of both supersonic and subsonic loads making it one of the more versatile modern rifle cartridges.
