I am going to get a 300 Whisper or Blackout upper for my AR. The versatility of it intrigues me but it would mainly be a range toy with thoughts of possibly getting a can in the future. Which cartridge is more desirable?? I am leaning toward the ACC Blackout because it is SAMMI accepted and there are published specs. From what I understand they are not interchangable so I would need to pick one.
