Have an FN49 .30-06 for the Colombian armed forces. Bought it sometime in the mid 60's for $50.
Only downside / upside to the rifle is the gas port relief adjustment. It must be adjusted for different loadings otherwise the action may not cycle with mild reloads or it may blow the top barrel shroud off with hot reloads. I reload to M1 specs using CCI NATO primers (to lessen slam fires) and FMJ boattails. The gas adjustment is right on the money for this round.
Nice rifle with simple field stripping and cleaning. Enjoy it.
