I agree with Dater. After shooting an XM177E2 clone back in
the late 70s, I realized an ultra-short 5.56 was mostly "full of sound and fury, signifying nothing". The blast was absolutely ridiculous. Granted, it had a regular M16A1 flash suppressor on it at the time. As I recall, it had been tinkered with quite a bit to get it to function reliably with the short barrel and gas system.
If a person is determined to have an ultra-short AR, 300BLK would be a much better chambering.
Doc Dater has been around the suppressor industry for a long while.
