Fixed rear site base change when rebarrelled??

[Ed42]

I’m pretty new to the M1903 but I’m learning thanks to you folks and a couple of good books. I’ve been reading Poyer’s book and Canfield’s on the M1903 while trying to fill out the M1903 Data Sheets. My 03 is a 1918 Rock Island Armory rifle with a Springfield 8 42 barrel. Serial is 2940xx.

Question: How common was it when the rifle was rebarrelled in 1942 to also put on what I think of as a 1903 Modified rear fixed sight base WITHOUT the lightning cuts? It’s rounded on both sides .. no lightning cuts. Other than the rounded side rear fixed base, I don’t believe I have any other “1903 Modified “ features (maybe the slide screw.. windage knob)? From what I’ve been told by folks on the forums, this rifle went through at least two rebuilds in its life.. probably more. Any of your thoughts would be sincerely appreciated!!!! Cheers!

GI M1903 barrels had the rear sight base installed at the point of manufacture. They always came complete with the the rear sight base. Change the barrel, you get a new base.
