Thompson Center One Piece Mount, 25.4 mm

• One-piece ring and base design: The mount combines the rings and base in a single assembly, which simplifies installation and helps keep scope alignment consistent on compatible Thompson/Center firearms.
• Fits 25.4 mm (1 inch) scopes: This configuration supports a wide range of traditional hunting optics built on 1-inch tubes, making it a practical match for many established riflescope models.
• Billet aluminum construction: The aluminum build keeps weight down while still providing the rigidity needed for a secure optic mounting platform in field use.
• Anodized black finish: The protective finish helps the mount resist wear and blends cleanly with common rifle and muzzleloader finishes for a tidy, low-glare setup.
• Made for Thompson/Center platforms: It is designed around specific T/C firearm families and uses the existing factory-drilled holes, reducing the need for additional fitting work on compatible models.

About the Thompson Center Mounts Series

Thompson Center Mounts was developed as a practical optics-mounting line for shooters using the brand’s hunting and specialty firearm platforms. Within the wider Thompson/Center accessory offering, this series focused on integrated one-piece scope mount and ring combinations that attach to the firearm’s existing factory-drilled holes. That approach keeps installation straightforward and gives owners of compatible T/C models a direct way to add a riflescope without piecing together separate bases and rings.

The series covered both 25.4 mm (1-inch) and 30 mm scope tubes and included different ring heights to suit common optic sizes. A defining characteristic of the family is its lightweight machined anodized billet aluminum construction, chosen to reduce unnecessary bulk while maintaining the stiffness needed for a stable sighting setup. These mounts were cataloged across several Thompson/Center firearm families, including Encore/Pro Hunter, Triumph, Impact!, Omega and Contender/G2 Contender models. Compared with today’s T/C scope-mount offerings, which emphasize cross-slot and Picatinny rails, this earlier one-piece ring-combo series reflects a more integrated, model-specific mounting philosophy.

About the Thompson Center One Piece Mount, 25.4 mm

The Thompson Center One Piece Mount, 25.4 mm is a fixed optic mount built for shooters who want a clean, direct way to install a 1-inch riflescope on compatible Thompson/Center firearms. Because the rings and base are combined into one unit, the mount reduces the number of separate parts in the system. In practical use, that means a simpler installation process and a setup that stays visually tidy on break-action and muzzleloader platforms where compactness matters.

This model is especially well suited to traditional hunting optics, where the 25.4 mm (1 inch) tube format remains common. It is compatible with several established T/C platforms, including the Contender, Encore Pro Hunter, FX Pro Hunter, Omega, Triumph and Impact families, making it relevant for users who want to keep a dedicated optic on a specific firearm. The one-piece layout also suits field rifles and muzzleloaders that benefit from a mount matched closely to the receiver pattern rather than a more universal rail-based arrangement.

Its aluminium construction keeps the mount light enough not to add unnecessary top weight, while the black finish gives it a subdued appearance that pairs naturally with hunting and sporting firearms. As a fixed mount, its role is straightforward: provide a stable, model-specific platform for a 1-inch scope, with an integrated design that favors simplicity, low weight and a close fit to compatible Thompson/Center actions.
