Talley Picatinny Base for Kimber 8400 LA

• Kimber 8400 long-action fit: This Picatinny base is made for the Kimber 8400 Magnum platform, giving a correct interface for a secure scope installation without improvised spacing or mismatched hole patterns.
• Steel construction: The steel body adds rigidity and recoil resistance, which helps keep the optic stable on hard-kicking hunting rifles and supports repeatable zero retention over time.
• Picatinny rail format: A Picatinny Rail layout gives broad compatibility with modern scope rings and sight mounts, making it easier to position optics for proper eye relief and preferred shooting setup.
• Low-profile height: With a 4.00 mm base height, the rail keeps the optic close to the bore line, which can help maintain a practical cheek weld while still providing the flexibility of a rail system.
• Made in USA: Built in the USA, this Talley base reflects the brand’s focus on precise machining for firearm-specific fit and dependable day-to-day use in the field.

About the Talley Bases Series

Talley Bases are built as a traditional mounting option within Talley’s scope-mount lineup, aimed at shooters who want a solid interface between rifle and optic. The series is offered for numerous firearm models, which allows each base to be matched to the receiver it was designed for rather than treated as a generic fit. Talley states that these bases are machined from solid bar stock, a construction approach chosen for strength, dimensional consistency and dependable alignment.

A defining feature of the series is Talley’s double recoil shoulder design, intended to hold the optic firmly under recoil and reduce movement between rifle, base and rings. Talley also notes that each design is checked for fit to the firearm it serves, which is especially important on hunting rifles and magnum actions where mounting security matters. Within the broader Talley range, these bases support users who prefer a conventional two-piece or rail-based mounting system and want compatibility with Talley ring solutions while keeping the installation specific to the rifle platform.

About the Talley Picatinny Base for Kimber 8400 LA

The Talley Picatinny Base for Kimber 8400 LA is a rifle-specific mounting solution for the Kimber 8400 Magnum action, built for shooters who want the flexibility of a rail rather than a fixed ring-and-base arrangement. On a long-action hunting rifle, a Picatinny base makes it easier to fine-tune scope placement for eye relief, especially when using larger optics, longer main tubes or setups that need more fore-and-aft adjustment than traditional bases usually allow.

This model uses a steel construction, which suits rifles that generate substantial recoil and benefit from a rigid mounting platform. The added stiffness helps maintain alignment between receiver, rings and optic, while the rail format broadens compatibility with a wide range of Picatinny scope rings. That makes the base practical for hunters changing optics, moving between different ring heights or setting up a rifle for different loads and field conditions.

The 4.00 mm base height keeps the rail relatively low, helping preserve a sensible optic position over the bore while still delivering the versatility expected from a Picatinny interface. As part of Talley’s American-made mounting range, this base is intended for shooters who value straightforward installation, firearm-specific fit and a durable platform for hunting optics on the Kimber 8400 long action.
