R3-A6- ok, the body is from an episode 1 r2d2, the head is from a buble from a gumball macine, and the "guts are from legos and various guns. First, I sanded down the dome to the right size with my cutting wheel with my dremel. Next, I made a strip around the bottem of the buble with a computer label. Then, I glued on the eye and the scope. After that, i built the inside with some lego peices and a boba fett rifle. I painted the insides silver and black and the outsides as shown. Make sure that you dont put in to many guts so the head can still fit on.
