I’d look at Witt machine’s canooter valve on the low end
https://wittmachine.net/product/canooter-valve/I went with the Huxwrx Flow 5.56K on my 11.5” gun and 16” gun. My 14.5” gun is pinned and welded which sucks or it would run the Huxwrx too.
I was very surprised how pleasant both my guns are to shoot without ear pro now. I get zero gas to my face, even when I shoot left handed.
I’m thinking of the canooter valve for a couple of my other guns cause I don’t want to shoot unsuppressed again.
