Swiss GP11 ammo: noncorrosive, so bores are typically in excellent condition. The 03's value depends on its bore condition, which must be carefully inspected.

There are NDT scope mounts and diopter sights for the K31, so more shooting options. The only ammo available now is Prvi Partizan or reloads.

Do not buy any 03 remotely without inspecting bore condition. Been there, was had by that. Luckily for me a local guy rebarrels 03's and I got out from under. Do not assume any 03 or 03-A3 has bore condition like a Swiss straight pull or Swedish Mauser. The Swiss and Swedes were never used with corrosive ammo; not so for the 03.

1903 is worth about twice more then the k31

As I mentioned earlier, the 03 bores are likely to be in poor condition, owing either to heavy wear or neglect, i.e. pitted by corrosive ammo.

You cannot simply state that an 03 is worth 2x K31 without confirmation that the bore is not ruined. On the other hand, a K31 bore is more than likely to be in VG to excellent condition.
