If you do that it will make your rifle worth about $250 as an action to build on, maybe a little more depending on which M98 it is. Don't touch a thing on it if it is an un-molested M98 rifle. If you want to shoot it with a scope put ATI stock
on it. You still can't run a standard scope on it without a bent bolt handle but you can run a "scout scope" set up.
If you want a sporterized M98 just go on Gunbroker or Auctionarms and buy one already D&T for a scope. I love old military sporters but I will not destroy a military rifle to build one. I'd sell the rifle before I put a drill to it.
