The upper itself should be printed with the same settings at the normal upper, the sleeve should be solid and (optionally) printed in Nylon (to shield the upper from barrel heat). Unlike using my sleeve and the normal upper, this one will prevent the barrel from spinning (I had issues with it spinning when trying to remove my fake can).
