Running a thirty on that short of a barrel, you really need the blackout baffles to help extend the life of the suppressor internals. I use the original, and am not familiar enough with their 2.0 version to offer a definitive opinion as to the differences. That being said, I worry more about my equipment than shooters next to me. I do try to go to the end bench when at a public range, and shooting un-suppressed. I want to be as courteous as possible, but I don't buy parts so others can be "comfortable". Really wish I could be more help on your actual question. I looked at their (AAC) website and the current photos shown for the 51-T Blackout devices look like the ones I am using - photo below is on one of my uppers (purchased and installed a month ago) - it looks exactly like the first one I bought three years ago.
Edit: Sorry !! I re-read your question; and on the first pass I read "Blackout" instead of "Brakeout". I was looking on their website for a version 2.0 of the Blackout ! I did purchase a Brakeout (original) for the Colt LE6920 - shown in the second photo. It is used mostly un-suppressed, but all the uppers have mounts on them so I can put a can on if I want to. Now that I have my head pulled out of its' normal resting place, I can comment. Unfortunately the comment is - I really can't tell a lot of difference. The first baffle on the Brakeout sends all the noise your neighbors can stand. I think it would require a decibel meter appropriately placed to the side for a definitive reading on noise levels. The human ear (spell that anyone shooting near you) will hate them equally. Hard to imagine that putting a taper on the prongs would help enough to be able to tell a difference. That plays back to my personal thought - buy a mount that helps the suppressor. Extra baffles for the initial fireball do work ! I would strongly recommend the Blackout.
I apologize for any confusion the first comments may have caused.
