RE: German k98 8mm Mauser
With the history behind your rifle, your grandfather brought it back,I would leave it alone, the reason the bolt doesnt match is because when our troops returned home the bolts were taken from the rifles and shipped back seperate, when they got back to the states they had to just grab a bolt for their rifle!, to me, it makes the rifle worth more than ones that are even being imported here now with matching numbers. Some companies make non-drill scope mounts, but Ive never seen one that will hold a zero, waste of money!. By the way, you mentioned sellin it, if your not aware, your grandfather fought in one hell of a war and survived to bring it back, you should understand the real value of that weapon and hand it down through generations, teach the younger generations the sacrifices that were made for them to be liveing in this great nation!.
