About the .300 AAC Blackout Cartridge

Cartridge Development:

The .300 AAC Blackout, also known as 7.62×35mm, was developed by Advanced Armament Corporation (AAC) in 2009 and produced since 2010. This intermediate cartridge was designed to optimize performance in shorter barrels and to provide effective subsonic performance when used with silencers. It was initially intended for use in the M4 carbine, offering improved performance over the 5.56mm NATO, especially in specialized operations where subsonic rounds were advantageous.

Known for its versatility, the .300 AAC Blackout allows for the use of standard 5.56mm NATO magazines and components, with the exception of the barrel. This cartridge can penetrate barriers, making it effective in a range of tactical scenarios. It has seen adoption by military units, including the United States Special Operations Command and special forces from other nations like the Netherlands and Germany.

Cartridge Composition and Manufacture:

The .300 AAC Blackout cartridges typically feature full metal jacket bullets with copper plating, available in various configurations, such as supersonic and subsonic. This versatility allows users to switch between different types of ammunition without altering the firearm, making it ideal for a wide range of applications, from close-quarters combat to long-range engagements.
