Ar15 recievers drawings

I am looking for both AR15 upper and lower receiver drawings in CAD format that include detailed dimensions to be used for machining purposes. The CAD drawings should be of a very high quality in order to be accurate at production level. Furthermore, I need all component parts and their associated parts drawings including the receivers and their associated materials, finishes and any other associated details, 7075 aluminum, and milspec dimensions as 80% lower and 100% complete upper. The drawings and CAD files should be provided in a way that can be easily used for machining of the receivers when needed. Lastly, I require a few change revisions for our company specific designs with our logo or company marking on the right magwell. Thank you.
