Tier-One Pair of 11mm Dovetail Rings, 30 mm

• 11 mm dovetail fit: This ring set is built for rifles and rails that use an 11 mm dovetail, giving a direct mounting solution without adding the extra height and bulk of a separate rail.
• Matched-pair machining: Each pair is machined as a matched set from a solid billet, so alignment is kept tight and lapping is not required, saving setup time and helping protect the scope tube.
• 7075-T6 aluminium construction: The use of 7075-T6 aluminium keeps the rings light while maintaining the rigidity needed for consistent scope retention under regular field and range use.
• 5-axis CNC production: Tier-One machines these rings on 5-axis CNC equipment with a reduced number of manufacturing operations, which helps maintain repeatable tolerances and dependable fit.
• Custom stainless-steel screws: The supplied stainless-steel screws are made for durability and secure clamping, supporting reliable installation and long-term service.

About the Tier-One Dovetail Rings Series

Tier-One Dovetail Rings sit in the company’s scope-mount range as a direct-fit solution for rifles that use traditional dovetail interfaces rather than Picatinny rails. The series currently includes 11 mm Dovetail Rings alongside separate Tikka-specific rings, with the two lines covering different dovetail formats. This makes the range particularly relevant for rimfire rifles, sporting rifles and precision platforms that retain factory dovetail cuts.

A defining characteristic of the series is the way the rings are produced. Each set is a matched pair machined from a solid billet, and Tier-One states that lapping is not required. The manufacturer also emphasizes a machining process that reduces production from eight operations to two, helping preserve alignment by limiting re-setting between stages. In practical terms, that design philosophy focuses on consistent fit, secure scope support and straightforward installation. The series is also built around 5-axis CNC machining, 7075-T6 aluminium construction and custom stainless-steel screws, combining low weight with the rigidity expected from a precision scope-mounting system.

About the Tier-One Pair of 11mm Dovetail Rings, 30 mm

The Tier-One Pair of 11mm Dovetail Rings, 30 mm is designed for shooters who need a clean, direct way to mount a 30 mm riflescope onto an 11 mm dovetail. That makes it especially suitable for rifles that already use this mounting standard, where adding a separate rail would increase height and complexity without adding practical benefit. By keeping the optic close to the action, the ring set supports a compact overall setup and a more natural cheek weld.

This model follows Tier-One’s matched-pair approach, with the rings machined from a solid billet to tight tolerances so lapping is not required. That matters in practice because proper ring alignment helps reduce stress on the scope tube during installation, while also making the mounting process faster and more predictable. The 7075-T6 aluminium construction balances low weight with the stiffness needed to keep the optic stable through repeated use, and the custom stainless-steel screws are chosen for secure clamping and durability.

The ring set is finished in black and uses a KR 0.0 mm extension format, with no windage adjustment. This keeps the design simple and mechanically straightforward, which suits rifles and optics where correct alignment is achieved through the receiver or dovetail itself. For hunting optics, target rifles and general sporting use on compatible 11 mm platforms, this Tier-One mount offers a precise, low-profile interface focused on repeatable scope positioning.

About Tier-One

Tier-One was incorporated in early 2008 and is based in the United Kingdom. The company specializes in shooting accessories such as rifle scope mounts, bipods, moderators and related precision components. A key part of its reputation comes from making products in-house on its own five-axis CNC machines, giving the company direct control over machining quality and consistency.

Within the optics-mounting segment, Tier-One is also known for manufacturing precision scope rings for Zeiss USA and for producing OEM products for brands including Blaser, Sauer, AI, and March. Its lineup includes one-piece and two-piece mounting systems, with the Monomount serving as the company’s one-piece rifle scope mounting design. That background is directly relevant to products such as these dovetail rings, where machining accuracy, repeatability and material quality matter as much as the basic fit.
