In response to your actual question, no. There is no 10.0 perfect gun out there (yet).
However, this last spring, I gathered together some of the top engineering minds and we began a project code-named "Silver-Bullet".
Its goal was to built the perfect homemade rifle.
You can see our results thus far at this link in the SSC forums:

Throughout the whole process, I used the program Blender-3D to create digital models of the Silver-Bullet, so that people could see it for themselves and make suggestions.
If you look back through the history of that thread, you can see that it has evolved quite a lot from its humble beginnings.
