Critch,
The AR did do an article about 10 years ago give or take. The M40's I saw had Redfield Jr mounts and Redfield 3X9 scopes. They had wood stocks and very heavy barrels. Middle 70's some "surplus" M40 stocks were available and I purchased two both glass bedded.
Hathcocks m70 was a target rifle, not a sporter as seen in the pic..
