Leupold STD Two-Piece base, Kimber 8400 RVF

• STD mounting interface: The Leupold Standard system uses a front dovetail and rear windage screws, giving a secure scope-to-rifle connection while still allowing practical alignment during installation.
• Two-piece base layout: A two-piece design keeps the ejection port open and leaves more access to the action, which is useful on hunting rifles where loading and unloading should stay straightforward.
• Steel construction: Steel bases add the rigidity needed for a dependable mount, helping the optic stay in place under field use and repeated recoil.
• Kimber 8400 RVF fit: This base is made specifically for the Kimber 8400 receiver pattern, so it provides the correct interface without improvised fitting.
• Matte finish: The matte surface keeps reflections down and matches many hunting optics and rifles, giving the setup a more practical field-ready appearance.

About the Standard Series

Leupold Standard (STD) bases and rings sit in the brand's long-established line of traditional riflescope mounting systems. The series is aimed at shooters who want a proven steel mount for hunting rifles and general sporting use, with a design that balances secure lockup, straightforward installation, and broad rifle compatibility. Rather than using a one-piece tactical rail format, the STD system follows a classic arrangement with a front dovetail ring interface and rear windage adjustment screws.

That layout gives the series its practical identity. It allows the installer to make lateral corrections at the rear base while bore sighting, which can help preserve more of the riflescope's internal adjustment range for zeroing or ballistic dial use. The two-piece variants in the series also keep the action more open than a full-length rail, which suits traditional bolt-action hunting rifles. Across the range, steel construction and model-specific fitment are central features, making the Standard series a sensible choice for shooters who value a compact, durable mounting solution over extra rail length or accessory space.

About the Leupold STD Two-Piece base, Kimber 8400 RVF

The Leupold STD Two-Piece base, Kimber 8400 RVF is a rifle-specific mounting solution built for shooters who want a clean, traditional scope installation on a Kimber 8400. Its two-piece configuration keeps the receiver area more accessible than a one-piece base, which is especially useful on a hunting rifle where easy access to the loading port and action matters in daily use.

What sets this model apart is the way it combines that open layout with the practical advantages of the Leupold Standard interface. The front dovetail engagement provides a solid anchor point, while the rear windage screws allow lateral adjustment during setup. In practice, that can simplify alignment and reduce the need to use as much internal windage correction in the riflescope itself. For shooters using ballistic elevation dials, preserving more of the scope's adjustment travel can be a real advantage.

The base is made from steel, which suits a mount intended to stay rigid and dependable over long-term field use. Its matte finish keeps glare low and pairs naturally with blued or matte-finished hunting rifles and optics. This model is also part of Leupold's receiver-specific fit system, so it is designed around the Kimber 8400 pattern rather than as a universal compromise. The result is a compact, practical base for a traditional hunting optics setup.

About Leupold

Leupold & Volpel was founded in Portland, Oregon, in 1907 by Fred Leupold and Adam Volpel. The company later expanded into sporting optics and introduced its first riflescope, the Plainsman, in 1947. That early move into riflescopes helped establish Leupold as a specialist in optics for hunting and shooting rather than a general outdoor brand.

Today, Leupold & Stevens, Inc. is headquartered in Beaverton, Oregon, United States, and remains family-owned. Its product range covers riflescopes, red dot sights, binoculars, spotting scopes, rangefinders, and thermal optics, with a strong focus on practical field use. In riflescopes, the company is also known for the Duplex reticle, introduced in 1962, and for established lines such as VX-series and Mark-series optics. That background is directly relevant to its mounts, which are built to support the same hunting and shooting applications as the optics themselves.
