Not resin/definitely not "fake" - it was a second set of Bapty-made parts that were sent to Stembridge for the live fire ROTJ Han blaster. The flash hider was machined aluminum, the scope bracket was white Delrin, the mounting screws and spacers were brass, the piston halves were machined black Delrin, and the small plate to cover the Mauser logo on the left side was aluminum.
The scope was as you described - machined black Delrin rear bell w/ a shaft that fit the scope ring (no spacer), plastic cap front that was pop riveted to the Delrin shaft, scope adjustment knob cap for the small knurled cap on the front. And I'll be damned... I always wondered what the hell that thing was in the tip - definitely a steel screw.
