While you are on the site, in your browser find and click "Add to Home Screen" A CGN beaver app icon will then be created to your phone that is directly link to the site.
Note: This feature may not be available in some browsers.
I'll save posting the link, but Google "M14 Manual" and there are several sites with it.
Also, check out some of the M14 forums that are out there, I don't think you'll be disappointed.
There was a link posted 2 or 3 weeks ago. It was on another site that you had to register on to access but it is a great site for M14 stuff. I downloaded and printed the "how to dissassemble a M14" stuff.
