fartanspartan: You get a back that is one color, the multi-colored inserts go inside it and are not seen except while changing them (or if you look down your barrel ).
yea i never had or really looked into barrel kits much but before buying one i asked the person selling them a few questions and got it all straightened out. I just figured all the colored sections were backs it never crossed my mind when i read inserts that they were inserted into the barrel back. thanks for the info tho.
