S&K makes a scout mount. St. Marie makes clamp on and drill and tap mounts. http://www.swissrifles.com/~swiss-sights/
I've been using clamp-on scope mounts - and they are amazingly tight and repeatable. I wouldn't try to drill and tap swiss receiver - they are extremely hard.
GP11 is the Swiss standard issue ammo. That said, it is usually considered at/near match quality my most K31 shooters.
I've been using the clamp on mounts too. They work extremely well and you can really use them almost as a QD mount. They are a little annoying though because they mount off center to the right. That makes you have to kinda lean your head over the butt to align your eye to the scope.
Some interesting information posted here. As someone mentioned, the K31 in its standard configuration can be gotten for less than $300 for a walnut-stocked version; the beech-stocked issues go for a bit less. Even then, it's not unusual to find a K31 that has MOA accuracy with the standard-issue GP-11 ammo. With a St. Marie clamp-on scope mount and a Weaver K4-1 scope, my K31 is easily the most accurate rifle I own for 100-yard shooting. Heck, with a P/S diopter sight, the K31 is scarily accurate.
So for a M700 to be comparable to a K31 in terms of accuracy, you'd have to sink quite a bit of money into the former, it would seem.
I just bought my first K31. I'm a lefty so maybe this clamp on would be good??
Do you have a dickens of a time operating the straight pull of the right-handed bolt? But if you don't mind that arrangement, a St. Marie clamp-on mount would be nice for a leftie. You might have to work on your cheek weld though, perhaps even get a cheek pad much like the one on a M1C or M1D.
I think a K31 would hold its own against an out of the box remington 700
A lefty friend of mine liked the off center scope arrangement, but did have some difficulty operating the bolt smoothly.
