SWISS k31 updated

I like this rifle setup! No lasting modifications, but bring a classic weapon into the modern era of accuracy... or at least as much as possible.

Forgive my ignorance, but have you bedded the action or barrel of this rifle? I don't know if the k31s benefit from that sort of thing.

Can you tell us some more about the bipod adapter? Who makes it, how does it attach, does it work on other rifles..

Thanks for sharing :)

Most K31 don't need any extra "bedding".
Original sytem uses upward pressure from the stock tip to dampen barrel vibrations.
That pressure was adjusted after the wood was compressed in service by adding steel shims between the front action screw block on the receiver and it's mating surface on the stock. IMHO this does more for good accuracy in thinner than bull barrels to help accuracy. Tunning is done by adjusting the barrel bands so that front band is lightly holding upper handguard on, but not tight enough to bind barrel's forward heat expansion. This is pretty much the only point beside the barrel shank where wood contacts the barrel. other barrel band should be loose enough that the retainer spring can easliy move in and out od it's recess in the stock without binding.
Front action screw should be tight, and rear action screw can fine tuned as to how much upwards tension is pushing upwards from the stock tip. It should not be completely lose. Area under front action screws acts as a pivot point, like in a seesaw lever.
K31s do not have the metal barrel collar the earlier Schmidt Rubins did.
 
Bipod adapter works with original front action screw and leather padded U collar that goes around bottom of stock, carrying the rifle's weight load for the bipod.

Bi-pod attachment stud moves inside the channel groove to move it to the front or rear of that channel.

When bipod is tighten into the stud, it locks into that position.

Nice scope on that K31 Diopter! I just purchased the same one and mounted it on one of my K31's (very little clearance above the rear leaf sight, mine is contacting slightly but holds zero with No issues). I will Pm you regarding additional accessories.

Ingenious bipod adapter. Leave it to the swiss to make it perfect, jah?

Thanks for the info. I don't have one of these to play with but I do like to learn.
 
Actually, it was designed in house at Swiss Products in the States, a small recently started machining sub-division of St.Marie Graphics. The owner, Pierre St.Marie is an American who was born in Alsace Lorraine (German: Reichsland Elsass-Lothringen). He did spend quite a bit of time in Switzerland in his twenties, enough to get a life long appreciation of their guns and dogs. They also machine aircraft parts, which explains the high quality.

Is Tradex the only Canadian supplier for the Swiss Products no-drill K31 scope mount? I see it listed on Brownell's in the states. It shows the mount on the Tradex site, but it's been marked öut of stock"for quite a while. Anyone know of another reputable Canadian source?

Thanks,
Dave
