The Mauser K98 rifle is a German-made firearm first designed in 1898 by the Mauser firearm company, whose skillfully built rifles and designs have become the standard by which others are judged even after 100 years. However, some believe the design of the old-style rear leaf sight on the K98 is less than ideal for aging rifle enthusiasts who need the aid of eyeglasses while target shooting. Removing the rear leaf sight on a Mauser K98 to replace it with a modern sight can be done with just a few tools.
Open the bolt-action lever and pull it back to verify the firearm is not loaded, and close it again. Lock the rifle in a gun vise. Now twist the bolt action up to the 12 o'clock position, and then pull it all the way back, press the bolt-stop at the end of the bolt guidance track and remove the bolt assembly from the rifle.
Unscrew the front screw from the rear leaf sight located midway between the bolt-action guidance track and the front of the barrel, on top of the rifle, using an ordinary screwdriver. Next, remove the rifle from the vise, turn the firearm on either side and tighten it into the gun vise again.
Tap out the rear leaf sight pin from the back of the sight using a punch tool and ball peen hammer, and then pull out the pin with a pair of pliers. Now remove the firearm from the vise and return it to its original position in the vise and tighten it down again.
Place the blade of the screwdriver straight down on the notch where the pin was located, and while pressing down on the notch of the rear sight leaf, pull the sight leaf away from the sight to remove it from the rifle.
Grasp the front of the sight base between the thumb and forefinger and pull up to remove it from the rifle. Finally, remove the spring from beneath the sight base now that it is exposed and the sight base has been taken off. The firearm is now ready for a modern sight to be installed.
