I have a VSR-10 G-Spec, and i have done some upgrading to it. I have added a longer outer barrel and inner barrel as well. The inner barrel sticks out of the outer barrel about 5 inch's. The silencer hides the exposed barrel. What i don't like is how the inner barrel is just free floating inside the silencer. So i was wondering if there was anything i could put inside the hollow silencer to give the barrel some support, or if there are after market silencers that are not hollowed out like the G-Specs stock silencers. Just trying to get some advice before i try and do something to it myself.
