Ive run 2 different cans on my 9” SBR and a Rem 700AAC gun

First was an AAC 762sdn6. Super quiet setup, but that can was too long and heavy for my liking on a short fast rifle.

I now run a Gemtech GMT300blk on that rifle. Its not nearly as quiet, but I cant even tell its hanging off the end of the barrel. It is quiet enough to take the edge off Supers and sounds like the bolt cycling with subs

Understand that in order to get an AR to run there must be enough gas to function. You will never get ultra quiet with a gas operated gun. I have loads for my 300blk bolt gun that are silly quiet. Those loads dont begin to cycle my AR. Same bullet weight, same velocity…different powder, much quieter.

Everything is a trade off.
