IGM - you can purchase new (unused) mil-spec barrels for the 98s from places like Sarco, Samco, or Numerich Arms (Gunparts Corp) and have it installled to keep the original mil-spec configuration. Most mil-surps with new, newer or good barrels often shoot as well as, if not better than, new sporters or unissued mil-surps.
You could probably get a new, unused that is, mil-spec barrel complete with steps for about $75 or less from one of these places, and have a ball. I think that if she shoots well enough without a scope you may wish to sporterize it further. And you can turn a plain jane 98, complete with mil-spec stepped barrel, into a beautiful sporter. There are different rear sights and bases set up like express sights (as with the Swede 98s) and beautifully ramped front sights and barrel bands made for those rifles that basically obscure the military look of the rifle.
For example - my Husquavarna made M49 is a 98 sporter. It is a straight M98 with sporter dressings - stock, rear sight and base, front sight and barrel band - otherwise the darn thing is just another M98 and it even had the military trigger in it. I installed a Bold Trigger with safety, installed a bolt block when I removed the wing safety and d/t for a scope. With both handloads and mil-spec ball she shoots one hole groups at 100 yds - my kind of rifle.
As for the Swedish 96/38s in 6.5mm - the Swedes would rebarrel their rifles when the bores began to look like new US made sporters (lolol, but just about), which is why they always shoot so well. HTH. Mikey.
