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.
Here we have a Faxon ARAK 21 upper receiver with two barrel assembly units. One 20” heavy barrel in 5.56 and one 16” medium barrel in 300 blackout. Both barrels and have about 200 to 300 rounds through them. This is a great little package if you have an extra lower receiver hanging around.

Just getting into reloading (yeah, I picked a hell of a time), and looking to tinker with some 300 BLK subsonic. I’ve heard good things about IMR 4227, but don’t necessarily want to go buy enough to justify hazmat only to find out it doesn’t like my setup.
Anyone out there local with a pound...

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! I’ve...
I would consider selling individual components but prefer to find a buyer for the whole upper. If no one bites I'll piece it out in a few weeks. Asking $320 for the complete upper which is about 50% off retail. Great condition
