BFG

The gun is one of the distinct features of the GP-04 and I can't say no to big guns. The only change I made is the stock of the gun. The barrel are made from two styrene tubes. The hardest thing is scribe the mid lines on the outer tube. Once this is done, it serves as a reference. I take a piece of tape 1cm long and 6mm wide and mark out the mid line of the tape with fine tip gundam marker. The location of the minus molds are from the mid line. Aligning the mid line of the tape with the mid line of the barrel to transfer the location of the minus mold.
