We were able to find a game 3D model but because we were creating this in CAD for manufacturing, the properties would not convert one to one.
Here is a quick example of the process in Solidworks to create this gun.
I then 3D Printed the entire gun to scale from the game (Printed on a Fortus 250mc)
This process was necessary as scale was a major issue. Ultimately the gun was scaled down uniformly.
Final Sample model before production. We started to work on a final CMF.
