I am no expert by any stretch of the imagination,but in my opinion you are doing the absolute right thing.I have brought the "life" back to as many military bolt guns as I have been able to.There are enough sporting rifles in the world and there are more being made ever day.What you are setting about doing will not make the rifle "original" but it will make a nice representative piece for your collection.I have also found that sometimes these are my favorite "shooters".I once owned an (S42G) K98 that was all matching and I also knew the man who brought it home from the 2nd world war.I didn't want to shoot it because I figured it was to valuable.It has since passed to a good friend of mine who collects K98's. He doesn't shoot it either.I never really had any trouble at all shooting a rifle that was brought back from the land of "sporter death".Don't get me wrong,I hold no fault with folks who like sporterized Mausers or any other sporterized military rifle.I myself have put some together from bare receivers, sometimes as sporting rifles sometimes back into military dress.Right now I am setting on a Turkish '93 small ring action that somebody yanked the barrel out of.It's all matching (bolt,trigger guard,floor plate,etc.).I don't know for the life of me why anyone would sporterize a '93 Turk.So I guess to get to the point I totally agree with you in re-fitting your K98 to it's proper military dress.For whatever that is worth.
