K31 is an awesome rifle. I had a St. Marie mount, but found the Rifle was as accurate within the distances I shoot w/ Irons. Sold the mount and scope as a package. The reason they have "beaver chew" is because the butt stuck out of the pack they used. When the soldier sat down, rested, in the snow, mud, brush it would go. I'm sure stacking in camp added. They were rode hard, but always maintained very well. The only one I kept is a 1952 beech stock. They all shot well, but the keeper is exceptional. Still have 5 60 round packs GP11, 20 piece norma brass, 200 piece Graf brass. Mine really likes 165gr Combined technology SPBT Moly bullets. Bought a bunch on close out some years ago.
