Tier-One Pair of 11mm Dovetail Rings, 34 mm

• 11 mm dovetail fit: This ring set is built for rifles and actions with an 11 mm dovetail, giving a direct mounting solution without adding the extra height and bulk of a separate base.
• 34 mm scope compatibility: The 34 mm ring diameter supports modern riflescopes with larger main tubes, making it suitable for optics that need greater internal adjustment and robust mounting support.
• Precision-matched ring pair: Each pair is machined to close tolerances from a solid billet, so the scope tube sits more evenly in the rings and does not require lapping, helping preserve alignment and finish.
• 7075-T6 aluminium construction: The aluminium body keeps weight under control while maintaining the rigidity needed for consistent scope retention in regular field and range use.
• Integrated bubble level: A built-in bubble level helps the shooter keep the rifle upright when mounting or checking the setup, which is useful for reducing cant-related error.

About the Tier-One Dovetail Rings Series

Tier-One Dovetail Rings sit within the company’s scope-mount range as a direct-fit option for rifles that use a dovetail receiver rather than a Picatinny rail. In this family, Tier-One separates its 11 mm dovetail models from its dedicated Tikka-format rings, giving rimfire, sporting and target rifles a mounting system matched to the receiver profile they were designed around. The series is built around the same manufacturing approach seen across the brand’s premium mounting products, with 5-axis CNC machining and a process that reduces the number of machining operations to help maintain alignment from start to finish.

These rings are made from 7075-T6 aluminium and use custom-made stainless-steel screws, combining low weight with the strength expected from a serious riflescope mount. Tier-One offers the range in medium and high configurations, with size options varying by model. A key characteristic of the series is that each set is supplied as a matched pair machined from a solid billet, so lapping is not required. In practical use, that design philosophy suits shooters who want a clean, rigid and repeatable mounting solution for hunting optics, rimfire precision rifles and other dovetail-equipped platforms.

About the Tier-One Pair of 11mm Dovetail Rings, 34 mm

The Tier-One Pair of 11mm Dovetail Rings, 34 mm is designed for shooters who need to mount a 34 mm riflescope directly onto an 11 mm dovetail action. That makes it especially relevant for rimfire trainers, small-bore target rifles and selected sporting rifles that do not use a separate rail system. By clamping straight to the receiver, the setup stays compact and avoids unnecessary extra interfaces between rifle and optic.

This model uses an aluminium body with black finish and a KR 0.0 mm extension, so it keeps the optic in a straightforward, neutral position over the action. For scopes with a 34 mm main tube, that matters because these optics are often chosen for their larger adjustment range and more robust tube construction; the rings need to hold that tube securely without introducing stress. Tier-One’s matched-pair machining approach helps achieve that, and the no-lapping design is a practical advantage for shooters who want a precise fit without extra workshop time.

A further useful detail is the integrated bubble level. On rifles used for target work or careful field shooting, keeping the rifle upright helps reduce cant and the point-of-impact shift that can come with it. The result is a ring set aimed at shooters who value a tidy direct-dovetail installation, solid machining quality and compatibility with modern 34 mm optics.

About Tier-One

Tier-One was incorporated in early 2008 and is based in the United Kingdom. The company focuses on precision shooting accessories, producing rifle scope mounts, moderators, bipods and related equipment for sporting, tactical and competition use. Its manufacturing approach is closely tied to in-house production, with components made on the company’s own five-axis CNC machines, which supports the tight tolerances expected from premium mounting hardware.

Within the optics-mounting segment, Tier-One is also known as a manufacturer of precision scope rings for Zeiss USA and has produced OEM products for Blaser, Sauer, AI and March. That background places the brand firmly in the specialist end of the shooting-accessories market, where repeatability, machining accuracy and mechanical consistency matter as much as raw strength. Alongside its ring sets, the company’s better-known product families include the Monomount one-piece mounting system and its Tactical and Evolution bipod lines.
