It seems to be quite a popular mod in America.
Like you say I think I'll need to try it. My barrel is 14mm od and I already have a carbon sleeve which is 18mm od x 16mm id. So I've ordered a 16mm od x 14mm id which should be a tight fit between the barrel and the shroud. I'll try this with just a friction fit and see if it offers any improvement. If it does I'll then need to decide if I'm gonna bond it on with epoxy for additional stiffness.
If your carbon sleeve is to tight a fit to go on the barrel ,i think I read that if it's put in the freezer it expands not contracts . May just get you that little extra required.
