Do you need any help getting stuff modelled for Gunstruction? I've got quite a bit of experience building 3D models (using Lightwave).
I haven't been able to work for a few years due to illness (and haven't even been able to get to the range for over a year), but could manage to knock out a part or two per week from home - which is in Spring, TX.
As an example of my work, I've uploaded some old renders to my webserver. No "stock" objects were used - everything in those images I modelled from scratch, taking measurements off of real-world items...
There are a few more images at:
http://www.steveday.com/3D/ , but the above are the highlights.
I still use it (Lightwave) to model home projects before committing to building anything.
I have a VLTOR MUR-1a which I was thinking about modelling, because it needs some material removed to accommodate the Magpul Pro rear offset sight. If you are interested I can start on that as an example, and then if you are happy we can negotiate for anything else.
