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.
