I just read today that J. Guthrie of the Sportsman's Channel Modern Sporting Rifles died April 12, 2013.
Guthrie, age 37, passed away in his sleep. He is survived by his wife and two children. Guthrie had teamed up with Dick Metcalf to co-host Modern Sporting Rifles, the first show of its kind about the AR 15 platform. Guthrie was also a noted outdoor writer who was featured in Guns and Ammo magazine as well as the NRA's American Rifleman. Those of us who shoot and hunt with the AR 15 have lost a true friend. Our deepest condolences go out to his family and friends.
