In Stock 300 BLK Ammo
ENTER TO WIN BENELLI M4 TACTICAL SHOTGUNThe .300 Blackout rifle cartridge is also known as 300 AAC Blackout, 300 BLK, and 7.62x35mm. Its design comes from the idea to develop a cartridge more powerful than AR-15’s native 223/5.56, with ballistics similar to those of the 7.62x39mm. This new cartridge had to work reliably with both supersonic and subsonic ammo, in the barrel that is less than 16 inches long. When fired through a suppressor, .300 Blackout bullets give a silent, yet powerful rifle. This ammo can be used for hunting, target shooting, as well as for home defense. Learn more about 300 BLK
300 Blackout Ammo
The .300 AAC Blackout is an intermediate cartridge designed to share ballistics similar to those of the 7.62x39 (AK-47 cartridge). It was developed for use in the M4 carbine and can be fired from a standard 5.56mm AR by only changing out the barrel.
It is also known as:
- 300 BLK
- 300 AAC Blackout
- 7.62x35mm
Advanced Armament Corporation collaborated with Remington Defense to develop a .30 caliber cartridge that would surpass the performance of 5.56mm ammo. This long-contemplated idea of replacing AR-15s native 5.56mm came to life after United States Government launched an international military campaign aka global war on terror after 9/11, and our troops found themselves in unfamiliar geography and unknown situations. The demand for a cartridge that has was more powerful and more silent lead to AAC developing 300 Blackout ammo for special operations forces, using a 5.56mm case cut down to fit a 30- caliber bullet.
When was 300 BLK invented?
Although AR-pattern rifles and carbines had been previously chambered in different 30 calibers, feeding issues were present with each attempt. Many ammunition manufacturers had tried and failed, including Colt Firearms. The solution was found thanks to wildcatters. One of the wildcatted cartridges - .300 Whisper served as a concept to get to the final result, and the one to be submitted to SAAMI. Development began in 2009, with the cartridge approved by SAAMI in 2011.
What’s the difference between 300 AAC and 5.56 / .223?
Even though both rifle cartridges are suitable for target shooting, hunting, and home defense,
there are a few differences between them.
300 blk bullet is stubbier, thicker, and heavier. 5.56mm NATO requires a longer barrel length, at
least 12”. Once you add additional few inches that suppressor takes, it becomes impossible to get
a powerful, yet short rifle.
On the other hand, 300 BLK works best in shorter-than-average barrels, which makes it super
suitable for suppressed use. 300 blackout works reliably with both supersonic and subsonic
ammo, but it shines when using subsonic and a suppressor, giving you a quiet and powerful
bullet.
5.56 has a faster velocity and shoots flatter, while 300 penetrates through more material.
300 BLK overcomes some of the shortcomings of larger calibers while providing the AR 15 with the possibility to shoot a larger round, with only switching the upper receiver.
