Good looking K31. These were such precision rifles that all bolts across all 20 + years of production and 800,000 rifles are interchangeable.
At least that is what I was told when I was concerned about the headspace of two mis matched K31's I purchased. Based on my headspace measurements, it is true.
The one thing I really want on those rifles is a windage gage. Such an accurate rifle and the windage is only drift adjustable.
If I'm not shooting, I'm reloading.
