300 blackout
The .300 AAC Blackout (designated as the 300 BLK by the SAAMI and 300 AAC Blackout by the C.I.P.), also known as 7.62×35mm is a carbine cartridge developed in the United States by Advanced Armament Corporation (AAC) for use in the M4 carbine. Its purpose is to achieve ballistics similar to the 7.62×39mm cartridge, or even more similarly, the 7.92×33mm Kurz cartridge in an AR-15 while using standard AR-15 magazines at their normal capacities. Care should be taken not to use 300 BLK ammunition in a rifle chambered for 7.62×40mm Wilson Tactical.

Is 300BLK gaining more popularity?
Last summer I bought a 300blk as a first rifle purchase and at the time my friends who are gun enthusiasts thought it was a bad purchase because the ammo was so expensive compared to the 22L, 223, and 556, but to be honest I just wanted to be different because none of them owned one.Lol!
