  • The name is a reference to AAC's .300 AAC Blackout cartridge designed specially for M4 carbines and other AR-15 platform rifles, SAAMI designation for this cartridge is 300 BLK and 300 AAC Blackout by CIP.
  • In real life, the cartridge was developed to fulfill a void found by many Special Forces soldiers, that required ammunition with better performance than a high energy standard velocity round (like the 5.56x45mm NATO cartridge), and superior subsonic performance when compared to a standard 9x19mm round. More specifically, it was meant to have terminal ballistics similar to the russian 7.62x39mm round, and the .300 Blackout ended with cartridge dimensions of 7.62x35mm.[1]
    • One of the requirements for the cartridge was a high degree of interchangeablity with a standard 5.56mm M4/AR-15 and the capability of being used in a STANAG magazine with no reductions in maximum ammunition count (i.e. Being capable of inserting 30 rounds of .300 BLK in a 5.56mm 30-round magazine). This was accomplished succesfully, with the only obligatory change to convert the firearm to .300 BLK being a barrel swap. No changes to the Fire Control Group or Bolt are required.[1]
  • Supersonic loads for the .300 AAC Blackout do exist, although when making use of them, the suppressor will have its effects diminished, as the supersonic projectile will break the speed of sound and produce a supersonic "crack", that cannot be completely suppressed. For that reason, subsonic loads are used to keep the sound signature as low as possible.[1]
