it's not a bad idea, but weather or not it's necessary is hard to determine until you actually start shooting a suppressor on your rifle.
If you're running a .30 cal can on your .223 (as many predator hunters do) then I would doubt you'll need it. The .30 can has a large enough volume and bore, that your back pressure likely wont spike the way it will with a .223 can.
Now, if you run a .223 can and you notice your brass is getting banged up, or you get stove pipes or pass overs...it's usually because your BCG is running WAY to fast because you're getting too much gas. An adjustable will fix it.
