Tier-One Pair of 16.5mm Dovetail Rings, 34mm

• 16.5mm dovetail fit: This ring set is built for rifles that use a 16.5mm dovetail interface, giving a direct, low-profile mounting solution without adding the extra bulk of a separate base.
• 34 mm scope compatibility: The larger ring diameter supports modern 34 mm riflescopes, which are commonly chosen for greater adjustment travel and more robust main tubes in precision and long-range shooting setups.
• Matched ring pair construction: Each pair is machined as a matched set from billet material, which helps maintain even scope alignment and reduces the need for corrective fitting before installation.
• Integrated bubble level: The built-in level helps the shooter keep the rifle and optic square, which is especially useful when trying to avoid cant-induced error at longer distances.
• Aluminium build: The aluminium construction keeps weight under control while still providing the rigidity needed for a secure optic mount on sporting and precision rifles.

About the Tier-One Dovetail Rings Series

Tier-One Dovetail Rings sit within the company’s precision scope-mount range as a direct-fit solution for rifles that use a dovetail receiver rather than a Picatinny rail. The series includes dedicated 11mm dovetail rings as well as separate Tikka-pattern rings, giving shooters a simpler mounting route for compatible actions. Across the range, the design focus is on precise machining, consistent alignment and clean installation rather than extra complexity.

These rings are machined from a solid billet on 5-axis CNC machinery, and Tier-One states that the manufacturing process uses two operations instead of eight. In practical terms, that approach is aimed at maintaining tighter consistency from one ring half to the next. The series also uses custom-made stainless-steel screws, and the matched-pair construction is intended to eliminate the need for lapping. Depending on the exact ring family, configurations are offered in medium and high heights, allowing the shooter to match objective clearance and preferred cheek weld to the rifle and optic combination.

About the Tier-One Pair of 16.5mm Dovetail Rings, 34mm

The Tier-One Pair of 16.5mm Dovetail Rings, 34mm is a fixed two-piece scope mount for rifles that accept a 16.5mm dovetail interface and carry a 34 mm riflescope tube. That combination makes it especially relevant for shooters using larger modern optics on compatible sporting or precision rifle platforms, where a direct dovetail mount can keep the setup compact and mechanically straightforward.

The 34 mm ring size suits scopes built around stronger, larger-diameter main tubes, often chosen for extended elevation travel and hard field use. Because this is a fixed mount with no windage adjustment, the design stays simple and solid, relying on the rifle and optic to be properly aligned rather than adding extra moving parts into the mounting system. The KR 0.0 mm extension keeps the rings in a neutral position, which is useful when the rifle and scope already provide the correct eye-relief relationship without needing forward offset.

The aluminium body helps keep the mount from adding unnecessary mass, while the integrated bubble level adds a practical aid for precise shot placement. On rifles used for longer shots, even a small amount of cant can shift impact, so having a level built into the ring set helps the shooter confirm alignment quickly from the firing position. Finished in black, the rings maintain a subdued appearance that fits well with both hunting optics and precision shooting rifles.

About Tier-One

Tier-One was incorporated in early 2008 and is based in the United Kingdom. The company focuses on shooting accessories such as rifle scope mounts, moderators, bipods and related components, with an emphasis on in-house manufacturing. Tier-One states that it produces its products on its own five-axis CNC machines, a detail that reflects the brand’s concentration on tightly controlled machining and repeatable fit.

The company is also known for supplying original-equipment-manufacturer products for Blaser, Sauer, AI and March, and for manufacturing precision scope rings for Zeiss USA. Within its mounting range, the Monomount is Tier-One’s one-piece rifle scope mounting system, while its ring and dovetail products serve shooters who want the same machining-led approach in more traditional two-piece formats.
