Talley Base for Kimber 8400 (Extended)

• Extended front base: the extended layout gives extra mounting latitude, which helps position scopes with shorter main tubes correctly on long or magnum-length actions.
• Steel construction: a steel base provides a rigid interface between rifle and optic, helping the setup stay secure under recoil and repeated field use.
• 0 MOA inclination: the flat base keeps the optic in a neutral mounting position, making it a practical choice for general hunting and conventional zero distances.
• Double recoil shoulder design: Talley’s base geometry is intended to resist movement under recoil, supporting more consistent scope alignment over time.
• Kimber 8400-specific fit: this base is made for the Kimber 8400 WSM and 8400 Magnum, so it suits those actions without the compromises of a universal mount.

About the Talley Bases Series

Talley Bases are Talley’s traditional two-piece mounting option for shooters who want a separate base-and-ring system rather than an integrated mount. The series is offered for a wide range of rifle models, with each base pattern made for a specific receiver footprint. Talley machines these bases from solid bar stock, a construction approach that favors consistent dimensions and a solid interface between rifle and optic.

A defining feature of the series is Talley’s double recoil shoulder design, which is intended to keep the scope mounting system stable under recoil. In practical use, that matters most on hunting rifles and magnum chamberings where repeated recoil can expose weaknesses in lighter or less secure mounting setups. Talley also states that each base pattern is checked for fit to the firearm it is designed for, reinforcing the series’ role as a model-specific mounting solution rather than a one-size-fits-all part. Within the Talley lineup, steel bases remain a traditional choice for shooters pairing them with Talley Fixed Rings or Talley Quick-Detachable Rings.

About the Talley Base for Kimber 8400 (Extended)

The Talley Base for Kimber 8400 (Extended) is a steel scope-mount base built for shooters using a Kimber 8400 WSM or Kimber 8400 Magnum and wanting more flexibility in scope placement than a standard base provides. The extended pattern is especially useful when mounting a scope with a shorter main tube, because it creates additional room to position the optic for proper eye relief without forcing compromises in ring placement.

Its steel construction suits hard-kicking hunting rifles where a rigid mounting foundation matters. On magnum-length actions, the mount has to do more than simply hold the scope in place; it needs to maintain alignment through recoil, transport and repeated removal and reinstallation of optics or rings. Talley’s base design addresses that with a recoil-resistant profile intended to keep the optic interface stable.

The 0 MOA inclination keeps the setup straightforward for general-purpose hunting optics, where a neutral mounting angle is usually the right starting point. A 4.00 mm BH height also helps keep the mounting profile controlled without adding unnecessary bulk. Finished in black, the base matches common riflescope and ring finishes and is designed to work with Talley Dovetail Bases compatibility above, making it a practical component in a traditional Talley mounting system.
