After consulting with my CMP match shooting friends on what rifle to buy for the Vintage Military class, I purchased the Swiss K-31 earlier this year. What an incredible gun it turned out to be. Simpsons LTD in Galesburg IL had racks of them, so took a while to pick through. But I couldn't be more impressed. This gun was graded at 98% finish, and honestly it might even be higher, there was zero rust or any other finish issue once I got it apart. Notice that all the serial numbered parts are matching, even the butt plate. Notice the alignment mark on the barrel/receiver (matching #s too). I had no idea where to set the sights, but figured close to the "2" should be good to start at 200 yards. I shot 40 rounds of Prvi Privastin the first time out and all 40 rounds were in the black of the standard 200 yard target. Only move the rear up two clicks, then back down one from where I started. Going to be a great match gun, I definitely love this thing.
