Description
Getting a reliable optic on a sporterized Mauser can be a headache, and Warne's Maxima two-piece steel base set takes the guesswork out of it. These bases are CNC machined from solid steel and held to tight tolerances, so you get a mounting platform that stands up to recoil and keeps your zero where it belongs. The matte black finish cuts glare and blends in with a classic Mauser build.
What the Mauser FN 98 Maxima Bases Fit
This set (part number M902/830M) is cut for the Mauser 98 four-hole altered receiver pattern, which covers Commercial Mauser, Mauser FN 98, and M98 altered actions. Altered Mausers have had the stripper clip hump ground off, so if your receiver has been machined flat up top and drilled in the four-hole layout, this is the base you want. It also crosses over to a long list of Mauser-action rifles including the Browning High Power bolt gun, Interarms Mark X, Charles Daly Mauser, Parker Hale, Remington 798, and Zastava M70, among others.
Why the Warne Maxima Base Design Works
The Maxima bases follow the proven Weaver-style footprint, one of the most versatile and widely supported mounting systems out there, so you've got plenty of ring options. Each base includes a full-width, full-depth recoil slot that gives the recoil keys on your rings maximum bearing surface, which is exactly what you want on a hard-kicking Mauser chambered in something like 7×57 or a bigger safari round. The low-profile steel construction keeps everything sleek and close to the bore.
Pairing With Warne Rings
These bases really shine when matched with Warne Maxima QD rings. The low mounting height lets you look right over the top of the bases to use your open sights without breaking your natural cheek weld, and with quick-detach rings you can pull the scope and go back to irons in seconds, then return to zero. Mount them up with the included Torx T-15 socket cap screws torqued to around 25 inch-pounds and you're set for a long time.

Frequently Asked Questions
What rifles do the Warne Maxima M902/830M bases fit?
This set is cut for the Mauser 98 four-hole altered receiver pattern, which includes Commercial Mauser, Mauser FN 98, and M98 altered actions. It also fits a range of other Mauser-action rifles such as the Browning High Power bolt gun, Interarms Mark X, Parker Hale, Remington 798, and Zastava M70. If your Mauser has had the stripper clip hump ground off and is drilled in the four-hole layout, this is the correct base.
Can I still use iron sights with these bases installed?
Yes. The Maxima bases use a low-profile design, so you can look right over the top of them to use your open sights. Pair them with Warne Maxima QD rings and you can remove the scope entirely and go straight back to irons, then return your optic to zero later.
What rings work with the Warne Maxima Mauser FN bases?
The bases use the Weaver-style footprint, so they accept a wide range of Weaver-pattern rings. They're designed to pair with Warne's own Maxima fixed and Maxima quick-detach rings, which take full advantage of the full-width recoil slots machined into each base.
How do I install these bases and what torque should I use?
The bases mount to your receiver using the included Torx T-15 socket cap screws. Warne recommends torquing them to around 25 inch-pounds for a secure, repeatable hold. A dab of thread locker on the screws is a good idea on a hard-recoiling rifle.
