I’ve converted it to an eBook:

Field Manual 23-5: U.S. Rifle, Caliber .30, M1

It’s a faithful rendition of what I think is the last edition (published in 1965), formatted for your Kindle or other compatible device.  Cribbed from the description I provided to Amazon:

An ebook conversion of the Army’s “owner’s manual” for the M1 Garand battle rifle. More convenient than the PDFs that exist, and easy to load into your phone so you have it on hand at the range or in the field. Includes information on basic handling and operation, field stripping, a description of how the rifle operates, how to resolve stoppages, and routine maintenance.
