Who made this American Custom Rifle?

[rookhawk]

I noticed today that my 1958 featherweight does not have the sight bulge. Had the featherweight come out yet at this time, or could it be later production barrel installed on an older receiver?

i have a 1956 fwt and it has the bulge in .243.

I’d check the serial on the belly of the barrel where it meets the action. (Remove stock)
