A bit, it's basically like a bar connecting the front of the barrel to the receiver, parallel to the barrel. But I don't think it would be sufficient to remedy your current problem.
I really think you need those spacers/shims in space. I've never been able to tighten down a barrel nut enough (even with a real steel armorer's wrench) to get a solid fit without those spacers installed (I'd describe the feeling as "the nut is as tight as it'll go, but the barrel is still loose").
