anybody have a good source for AR15 blueprints and sldprt files?

if it's a solid model i need something i can get dimensions off, the edrawings files don't alway allow that.
basically looking for an upper receiver right now. just messing around with some ideas in solidworks.

thanks

You can download iges files here. Not quite a SW model, but beats the e-drawings.
