Sorry, I should have given a better description of the gun.
Yes, it is a polished grey Z front and rear body on sandwiched between a long custom fabricated frame and sight.
The front of the body has that block attached to the front and the back where the asa would have been was chopped off (not to make it sound sloppy though) and the asa hole is plugged.
The barrel is an Armson with a muzzle brake.
Also, the blue Z clonesque maker I posted is the Falcon and if you haven't read Nick's writeup on it I would suggest checking out the following link:
