Jason, while I do from time to time share 3d models, I never share part of my business. That is not good business! I don't know about others, but the time it takes to develop the 3d model and good gcode it quite time consuming, and time equals......money! Now all that said, I do not have the model for that firearm but there is a chance you could find it on GrabCad at Free 3D CAD Library and Collaboration Tools for Engineers - GrabCAD If it is not there, you can also offer to fund it there, I think as a contest and have many people designing the same product.
Here is one I did for a Ruger 10/22. BTW, gunstocks and pistol grips is my main business.
Designed in Rhino v5 and machined with Madcam V5
