Sorry it took me so long to get back to this thread.
Yeah, the chrome version will need a lot of work. It's as close as you can get with airsoft though. I picked one up off of ebay (it was $30 then, now these guys fetch $65) along the way while building the live fire version with the intention of 3D printing the scope and mount. I did model out a new front sight for it but have not printed it.
I was planning to coat the gun in a matte clear to try and mimic the unpolished stainless look of the real deal.
The pachmayr rubber grips don't fit, and can't be made to fit, this airsoft either. I will eventually model out replica grips made specifically for this airsoft. Maybe I'll take a crack at that over the weekend.
If anybody is interested in the STL files let me know. I'll post them on thingiverse for free downloads.
