Hi Hawk!
I have the Kuhnhausen Shop Manuals, Duff's book and Poyer's book and I like them all... I actually use the Kuhnhausen and Duff books for all of the work on my rifles... I try to extract as much info before doing anything to save on making mistakes, which can add up!
Poyer's book is okay, some info I found interesting, but I think if you put a cover on Different's article on M14's it would be as, if not more, interesting. Now, I also know others that have wrote pieces on M14's, reloading, etc. and maybe it would be a good idea to see if we could collect all of this material and put it someplace that everyone could access... hmmm.... the Firing Line Library? Well, it was a thought.
Lot's of people here also have written procedures and that could be there as well or in the Knowledgebase section.... I know the stuff Bill Ricca has is "invaluable or worth its weight in gold"!
Just thinking...
Aloha,
Tom O.
