If you are going to be shooting all the time at one range such at 100 meters, then installing a higher front sight to bring the point of impact in agreement with the point of aim is one solution. However, if you shoot at longer ranges, then the sights are going to be off a bit and the markings on the sight will definitely not be in accordance with the point of impact. If you are shooting groups, the original sights are all right, but if you are shooting for score, then it is sometimes better to change the front sight blade.
First of all, look at the shape of your rear sight notch. Is it "V" or "U" shaped? Original notches were "V" shaped and used a "Barleycorn" front sight blade while later notches were "U" shaped and used a square front sight with parallel sides. Do not assume that because your rifle has an early date that it has the earlier sights, because the Swedes upgraded their rifles at regular occasions.
Look under the wrist of the stock just behind the trigger guard. There should be one or two single stamped crowns in the wood, but there is probably some stamped crowns with a letter underneath. These denote visits to the Arsenals or Tygstations (repair depots) for upgrades, alterations, or repairs, including barrel changes. If there is a "Crown S" or a "Crown C" then it is quite likely the barrel has been replaced by Stockholm Tygstation or Carl Gustafs Arsenal. Replaced barrels do not detract from the value of the rifle and were done at regular intervals depending upon barrel useage and condition.
I agree that Trade-Ex is a great place to deal with, and they have an excellent reputation for customer service.
