300 Blackout

The 300 AAC Blackout, also known as the 300 BLK, is a rifle cartridge designed for use in the AR-15 platform. It was developed by Advanced Armament Corporation (AAC) in collaboration with Remington Defense in 2010, with the goal of creating a cartridge that would provide better performance than the 5.56 NATO round while maintaining compatibility with the existing AR-15 platform.


The 300 AAC Blackout is a relatively new cartridge, but it has gained popularity among hunters, law enforcement, and military personnel due to its versatility and performance. It is designed to provide exceptional ballistics, including accuracy, energy, and terminal performance, while being compatible with the AR-15 platform.


The 300 AAC Blackout cartridge is essentially a .30-caliber bullet (7.62mm) in a shortened 5.56mm case. This design allows the round to use the same magazines and bolt carrier group as the 5.56mm, making it easy to convert an existing AR-15 to 300 AAC Blackout. The 300 AAC Blackout round comes in a variety of bullet weights, ranging from 78 grains to 220 grains.


One of the primary advantages of the 300 AAC Blackout is its versatility. It can be used for a wide range of applications, including hunting, self-defense, and tactical situations. The cartridge is also an excellent choice for suppressed firearms due to its subsonic capabilities. When used with a suppressor, the 300 AAC Blackout can be extremely quiet, making it an excellent choice for hunting or tactical operations where stealth is essential.


Another advantage of the 300 AAC Blackout is its terminal performance. The round is capable of delivering a significant amount of energy to the target, which can result in a more effective stop. This makes the cartridge an excellent choice for hunting large game, such as deer or elk, or for use in tactical situations where stopping power is critical.


The 300 AAC Blackout is a versatile, high-performance cartridge that has become increasingly popular in recent years. It offers excellent ballistics, compatibility with the AR-15 platform, and is an excellent choice for hunting, self-defense, and tactical situations. Whether you are a hunter, law enforcement officer, or military personnel, the 300 AAC Blackout is a cartridge that should be on your radar.
