Standard barrels for the M1A/M-14 are the heavy pattern which is a full 1.100" diameter as far as possible from the breech to 1.000" diameter at the operating rod guide and continues at .990" diameter forward to the gas cylinder

Not true,
Standard barrels are the Goverment profile which is .580 just behind the muzzel.
In front of the op rod guide is.688 and .735 just in front of the chamber taper.
