*As it comes in two halves, customers must glue and screw them together themselves.
*The standard barrel length is the appropriate length for firing BBs.
*Making it longer will reduce the range. This is likely because the volume inside the barrel increases relative to the volume of vaporized gas in the cartridge, causing a negative pressure (?), and the resistance against the BB inside the barrel increases (?). (From the official MULE blog)
