What is not accurate as compared to the real prop:
Paintjob
Scope
Phantom Greeblies on the sides of the cylinder
Visible V8 greeblies on the stock near the grip
Rear Stock Greeblies
T-Track on the barrel
Here´s a short update of mine, based on the list you posted...
Scope:
Cobbled together a Frankenstein-scope that is nearly 100% accurate
Phantom Greeblies on the sides of the cylinder:
Removed the MR details, filled/ sanded the areas and added the real deal
Visible V8 greeblies on the stock near the grip:
Have two real ones that I´m going to use on my MR rebuild. It hurts me to think about destroying them to match the ones on the screenused blaster :cry
Rear Stock Greeblies:
Molded/ cast the correct right side detail.
-> Filled and sanded the holes in the shoulder stock, preparing to add the details via paper template.
T-Track on the barrel:
Won´t touch it, too much hassle :unsure
Paintjob:
This is going to be tricky, the blaster has such a defined, multi-layered paintjob that will be very hard to reproduce correctly :confused
