pewscience.com is a great resource, take a look at it before you buy. I run a Diligent Defense Enticer L-TI, it's a little longer than what you listed but only weighs 10.5 oz. It currently is listed as the #7 308 can on pewscience, at $865 it was my best choice. The #1 suppressor on their list is the PTR Vent 1, it's $1,400 and a couple oz heaver than my Enticer. I have mine on a Tikka roughtech ranch with a 16" barrel, it balances and carries well. I am really happy with the performance of it, you will want a lightweight cover to reduce the metallic ping sound it makes when hitting branches.
