Unfortunately I DID read the entire thread.......not much about your Kino......

I have a UBR on one of my 12.5s that I shoot suppressed a lot and it helps with the balance.

As for the breaks being loud, I have a AAC Blastout and it helps on the two that have breaks when they don't have cans on them.
