What is and where can I get the absolute best, profusely illustrated
depot level maintenance manual on the M-16 rifle. Prefer not to have
a reprint of military manual there not the best quality and rely too
much on drawings instead of detailed pictures.
i sometimes see them at gun shows.
online here
Good luck with your search. 
If you find such a manual please let me know.
I work with tech manuals and assembly drawings (aircraft) on a daily basis. I occasionally put together tech drawings myself. Drawings are still superior in illustrating and relaying information than photos are.
