Production dates for K31 Swiss Rifle serial numbers

I keep finding dead links to other K31 swiss sites that had this info, but are no longer online. Thought I’d post it here for posterity.

K31 swiss production dates by serial number

But first, a bit about why am I infatuated with the K31 Swiss?

  • Unparalleled craftsmanship in the milsurp category.
  • The Swiss managed to stay out of armed conflict during the service span of the K31. So, these rifles usually spent a lot of time in the rack and very little time being shot.
  • The K31 Swiss shoots 7.5×55 Swiss ammo (Brownell’s link), which was never issued in corrosive form.

The K31 presents a trifecta of awesomeness that means most K31 Swiss rifles are superior shooting rifles by any standard, let alone by the standard of mass produced military service rifles.  I have just acquired reloading dies for the 7.5×55 Swiss round and look forward to working up loads for better accuracy in my reloading press. I am thinking about accessorizing this one a bit with a scope mount, muzzle brake, and maybe a recoil pad (click here for Brownells link to these).
