Got so busy, forgot to take some pics. So I grabbed what pieces I have left and went with that.
First off. Drilled, Dremeled, filed and sanded the new holes.

Cleared out room on the inside.

Wanted a spring on the inside, but could not find one I liked. I bought some black pipe and wire. Painted the pipe black to match the blaster. Cut the wire into pieces and glued to the pipe to give the impression of a spring.

Enlarged the wholes in the ends of the scope. Removed the lenses from a pair toy binoculars and glued into the ends of the scope. (Lenses taped in the pic. Still needs painting and gluing to the main body of the scope.)

Cut up a Mt. Dew can and sanded for the ejection port. Glued on the Doopydoos. Added a couple other random parts. Gave the blaster an undercoat of silver and the scope gold. Painted over all with the black. This is where I am currently at.

Close up of the "spring". Need to touch up the paint alittle bit. Got in a hurry and taped up the gold before it was fully dried.

So what do you think so far?
