Just picked this rifle up last week and spent some time cleaning inside and out. I installed the stock screws at 20 inch pounds and went to the range. My 63 yr old eyes couldn't really focus at 100 meters well, but I managed to hit paper about 14" high. It has fixed iron sights, can anyone tell from the pictures if they are original? What should I do about getting it dialed in at 100 meters (or 200 meters)? Serial number is 353517, what year would this have been made? Also, does anyone know what the original stock finish is? I have some oil/wax stock finish from a swiss K31 and think this would also work on the Swedish rifle. Any other observations on this rifle would be appreciated. Thanks.
