Tier-One Pair of 16.5mm Dovetail Rings, 36mm

• 16.5mm dovetail fit: built for rifles that use a 16.5mm dovetail interface, giving a direct and secure mounting solution without adding the bulk of an extra base.
• 36 mm ring diameter: supports larger riflescope tubes used on specialist optics, helping maintain proper alignment and a stable hold under repeated use.
• 7075-T6 aluminium construction: the high-strength alloy keeps weight down while providing the rigidity needed for consistent scope retention and dependable zero.
• Matched CNC-machined ring pair: each set is produced as a precision pair from solid billet, which helps reduce fitting issues and supports even clamping without the need for lapping.
• Integrated bubble level: the built-in level makes it easier to square the rifle and optic, which is especially useful when trying to avoid cant on longer shots.

About the Tier-One Dovetail Rings Series

Tier-One Dovetail Rings are part of the company’s precision scope-mount range for shooters who want a direct-to-action mounting solution rather than a separate rail and ring combination. In the current lineup, Tier-One offers 11mm Dovetail Rings and separate Tikka Rings, giving users dedicated options for rifles built around dovetail receiver interfaces. Across the series, the rings are machined on 5-axis CNC machinery from 7075-T6 aluminium, with a design approach focused on precise alignment, low unnecessary mass and repeatable fit.

These rings are made as a matched pair from solid billet, and the manufacturing process is intended to deliver such close tolerances that lapping is not required. Tier-One also uses custom-made stainless-steel screws, reflecting the brand’s emphasis on durable hardware in critical clamping areas. In practical terms, the series suits hunting rifles and precision sporting rifles that use dovetail receivers, where a compact, rigid mounting setup is preferred. The result is a ring family that prioritises clean mechanical fit, dependable scope support and straightforward installation without moving away from the simplicity of a traditional dovetail-mounted system.

About the Tier-One Pair of 16.5mm Dovetail Rings, 36mm

The Tier-One Pair of 16.5mm Dovetail Rings, 36mm is designed for rifles that use a 16.5mm dovetail interface and for optics built around a 36 mm tube. That combination makes this model particularly relevant for shooters fitting larger, more specialised riflescopes to compatible actions while keeping the mounting system compact and direct. By attaching straight to the dovetail rather than through an added rail, the setup stays streamlined and avoids extra height or additional interfaces that can complicate the build.

The rings are made from aluminium and use a non-windage-adjustable design, which keeps the structure simple and rigid. For practical use, that means fewer moving parts in the mount itself and a setup that relies on precise machining rather than added adjustment mechanisms. The 0.0 mm extension keeps the rings in a neutral configuration, which suits rifles and scopes that already provide the correct eye-relief position without needing forward or rearward offset built into the mount.

A particularly useful detail is the integrated bubble level. When mounting a scope, it helps align the optic correctly to the rifle; in field use, it also gives the shooter a quick visual reference to reduce cant. That matters most when using reticles for holdover or wind correction, where even slight rifle tilt can shift point of impact. Finished in black, this Tier-One ring set is aimed at shooters who want a clean, robust dovetail mounting solution for a 36 mm riflescope on compatible sporting or precision rifle platforms.

About Tier-One

Tier-One is a United Kingdom-based shooting accessories manufacturer that was incorporated in early 2008. The company focuses on products such as riflescope mounts, moderators, bipods and related shooting accessories, with an emphasis on in-house machining and precision engineering. Tier-One manufactures its products on its own five-axis CNC machines, a production approach that supports the tight tolerances expected in scope-mounting components.

Within the optics-mount category, Tier-One is especially known for its Monomount one-piece rifle scope mounting system and for its precision rings. The company has also manufactured scope rings for Zeiss USA and produced OEM products for brands including Blaser, Sauer, AI and March. That background places Tier-One firmly in the part of the market where machining quality, repeatability and mechanical fit matter as much as the basic function of the accessory itself.
