Description
If you're mounting glass on a sporterized or commercial Large Ring Mauser 98, these Talley bases are about as dependable as it gets. Machined from solid steel bar stock with a classic blued finish, this two-piece set gives you a clean, low-profile foundation that looks right at home on a vintage walnut-and-steel rifle while still handling modern optics. These are built to fit the Large Ring Mauser 98 (and M12) with a .500" rear hole spacing, with front hole spacing coming in at .860".
What Makes the Talley Mauser 98 Base Hold Its Zero
The standout here is Talley's machined saddle design with double recoil shoulders. Those shoulders physically lock the rings in place so nothing creeps under recoil, which matters a lot on a Mauser chambered in a stout cartridge. It's a two-piece layout, so you get easier access to the top of the action for loading compared to a bridged one-piece rail, and it keeps the overall package trim and lightweight.
Picking the Right Talley Rings for These Bases
One thing worth knowing up front: this is a base system, and it needs Talley rings to complete the setup. The good news is these bases accept both Talley Fixed rings and Talley Quick-Detachable rings, so you can run a permanent mount or pull your scope off and put it back on without losing zero, depending on how you hunt. That flexibility is a big part of why folks keep coming back to this platform.
Fitment Notes Before You Order the Mauser 98 Bases
These fit commercial 98 Mausers and older military 98 Mauser actions that have been sporterized and drilled and tapped. They will not fit military Mauser receivers that still have the stripper clip hump, so if your action still has that charger bridge intact, this isn't the set for it. Beyond the 98 Mauser, the 252709 pattern also covers the Browning BBR built on a Mauser action, the Mauser M12, Heym, and the Remington Model 798. Made in America and machined to tight tolerances, it's a buy-it-once base set.

Frequently Asked Questions
Will these Talley Mauser 98 bases fit a military Mauser with the stripper clip hump?
No. These bases are designed for commercial 98 Mausers and older military 98 Mauser actions that have been sporterized. If your receiver still has the stripper clip charger hump, this set won't fit and you'll need a receiver that's been drilled and tapped for scope mounting.
Do I need rings to go with the Talley 252709 base set?
Yes. This is a base-only system, so you'll pair it with Talley rings to mount your scope. The bases accept both Talley Fixed and Talley Quick-Detachable rings, giving you the choice of a permanent setup or a removable one that returns to zero.
What hole spacing does the Talley Mauser 98 base use?
This set is built for a .500" rear hole spacing with a .860" front hole spacing. That's the standard Large Ring Mauser 98 and M12 pattern, so double-check your action matches before ordering.
Besides the Mauser 98, what other rifles does this base set fit?
The 252709 pattern also works on the Mauser M12, Heym actions, the Browning BBR built on a Mauser action, and the Remington Model 798. As long as your action matches the Large Ring Mauser 98 hole pattern with .500" rear spacing, you're good to go.
