I like that idea, first I've heard of it, using dense foam. Get a dollar store 'flutter board' and buy a circle cutter set, cut as close as you can to the inner diameter of your outer barrel and 1/4" in the middle of the disk, shove onto your inner barrel and stuff in. Should work just fine without deflecting the iner barrel (if you buy a quality one, they will be tough to flex).
But ya, they do stabilize the inner barrel and this increases the accuracy/consistancy. Is why most airsoft Armalites suck for that, they are only supported at the hop up, no where else.
