The 300AAC Blackout is a new and interesting cartridge that has been endorsed and embraced by manufacturers and shooter more than any other modern rifle in recent memory. The 300AAC Blackout gives an AR-15 shooter the ability to fire a 7.62/.308 bullet  from an AR-15 sized weapon. In fact there is only one part that needs to be changed on an AR-15 to fire 300AAC Blackout. That one part is the barrel. EVERY OTHER PART is the same including the bolt and magazine. Additionally the 300AAC Blackout is well suited for hunting, defense and with subsonic loads is a great suppressed round.

For me this project became a no brainer as I am waiting for approval for an AAC 7.62-SDN-6 sound suppressor and the two will go so well together.

 

 

Below is a hardware list for the parts used in this project. I have also provided links to my sources as well as any special notes. Pictures soon: You can also follow the project in it’s entirety here.
