Lol, I love the Dreamline. I have had several and three of my 15 guns right now are Dreamlines in different configurations. They are like the most popular rifle in America, you can build them into what you want.
Joedirt: It is a carbon fiber tube over a custom short barrel sleeve and liner. It is about the same diameter as the pencil shroud and not glued. It fits slightly into the receiver and is a tight friction fit over the liner. Much thicker than a standard FX carbon sleeve.
