I have never seen a factory Rem receiver contoured like that one, I suspect that a previous owner had the receiver machined in order to lighten the rifle a bit, especially since everything except the paint job appears to be to make it as light as possible. As thick as the paint is he probably added as much weight back on with it as was machined off.

223 Rem, my favorite cartridge - you can't argue with truckloads of dead PD's and gophers.
