A: From 1934 to the surrender of Germany in 1945, a total of seven factories produced over 14 million K98s.

9) Can I mount a scope to my K98?
A: Yes. There are several ways to mount a scope to a K98. The original mount required drilling and tapping the left side of the receiver. The side mount offset the scope enough so the bolt handle would clear and was high enough so the shooter could still use the iron sights. Original and reproduction side mounts can be found, but the originals will bring a premium price that often costs more than a rifle. There are also one- and two-piece, top-mounted scope bases available from companies like Leupold and Weaver. These require drilling and tapping the receiver and due to bolt handle clearance issues, extra-high rings will need to be used or the bolt handle will have to be modified by a gunsmith. Another type is the scout scope mount. This mount replaces the rear sight of the rifle and requires no gunsmithing, but does require the use of a long eye relief scope.

10) Are there replacement stocks made for the K98?
A: Yes. Several companies including Butler Creek manufacture replacement stocks for the K98. Stocks can be had in wood, laminated wood and synthetic materials.

11) How many rounds does the K98 hold in its magazine?
A: The K98 holds five rounds of 7.92x57mm ammunition in its internal box magazine. There was a magazine extension developed for the K98 that added 20 rounds to the original five. This extension is called the Trench magazine. The idea was that the extension gave the soldier in the trenches extra rounds to help fight off an enemy charge.

12) How collectible is my K98?
A: Collectibility of a particular rifle depends on many factors. When it was manufactured, where it was manufactured, the overall condition of the rifle, the particular variant, has it been modified, are all parts present, are all parts matching numbered and if it was a wartime bring back or a recent import will all affect the collectibility.
