The 1988 Film the Thin Red Line, I was watching it again, as it was one of the few Movies in the Pacific, with the Army and not those damn Jarheads. Other than the Post War M-1 Carbines in the Film with the Post War Bayonet Lug, I saw what was a M-1 Garand with an M-14 Upper hand guard! how is that possible? Knowing that the M-14 came out in 1957, and the M-1 Garand stopped in 1957. Did they start replacing the Upper Wood with the M-14 one? Would it even fit? Hope your Garand Guys know. Paul
