Tier-One 34 mm Long Monomount - Picatinny

• One-piece Monomount design: The mount is built as a single unit, which helps keep ring alignment consistent and reduces the chance of movement under recoil. That matters when a rifle is used for repeatable zero and dependable scope tracking.
• 34 mm scope compatibility: The 34 mm interface suits modern tactical optics and long-range riflescopes with larger main tubes, giving a solid platform for scopes that often carry more adjustment range and more robust internals.
• Long saddle layout: The longer body gives more clamping surface around the scope tube, which is useful for larger optics and for setups where mounting latitude and support across the tube are important.
• Picatinny fitment: Designed for Picatinny rails, this mount works with a wide range of precision rifles and chassis systems, making it a practical choice when moving between common tactical and sporting platforms.
• Aluminium construction: The aluminium body keeps weight under control while still providing the rigidity expected from a precision scope mount, helping balance rifles that already carry heavy barrels or large optics.

About the Tier-One Monomount Series

The Tier-One Monomount series is Tier-One’s one-piece rifle scope mounting family, developed for long-range shooters, hunters, and tactical professionals who want a rigid mounting platform with precise machining and straightforward rail compatibility. The series is built around a one-piece architecture that helps maintain alignment between the rings and the base, which is especially valuable on rifles used for repeatable dialing, transport in the field, and sustained recoil.

Across the range, Monomounts are machined from 7075-T6 aluminum and produced on five-axis CNC machinery, reflecting a design approach that prioritizes dimensional consistency and clean fitment. The family includes short- and long-saddle versions as well as cantilever, quick-detach, and competition variants, so shooters can match the mount to optic length, rail space, and rifle layout. Tier-One also includes an integrated anti-cant bubble on Monomount models, a useful feature for precision shooting where rifle cant can shift point of impact at distance.

About the Tier-One 34 mm Long Monomount - Picatinny

The Tier-One 34 mm Long Monomount - Picatinny is a fixed one-piece scope mount intended for rifles that need a stable interface between a 34 mm riflescope and a Picatinny rail. This format suits precision and tactical optics particularly well, as 34 mm scopes are commonly chosen for their larger adjustment range and robust construction. A one-piece mount helps support that kind of optic by keeping both rings in a single aligned structure rather than relying on separate bases.

The defining feature of this version is its long saddle configuration. In practical terms, the longer body gives more support across the scope tube and can make setup easier with larger day optics, longer erector housings, or rifles where rail space and eye-relief positioning need careful management. The listed KR 0.0 mm extension keeps the mount in a neutral position, which is useful when the rifle and optic already line up correctly and no forward offset is required.

Aluminium construction keeps the mount strong without adding unnecessary mass to a rifle system. The non-adjustable windage layout also keeps the design simple and solid, with alignment handled through the mount’s one-piece geometry and the rifle’s rail. For shooters building a dependable hunting optics or tactical optics setup, this Tier-One mount focuses on the essentials: secure clamping, clean scope support, and compatibility with established Picatinny-based rifle platforms.

About Tier-One

Tier-One is a United Kingdom-based manufacturer that was incorporated in early 2008. The company focuses on shooting accessories such as rifle scope mounts, moderators, bipods, and related precision components, with an emphasis on in-house production. A notable part of its manufacturing approach is the use of its own five-axis CNC machines, which supports the close tolerances expected in scope mounting hardware.

Tier-One is also known for producing precision scope rings for Zeiss USA and for supplying original-equipment-manufacturer products for Blaser, Sauer, AI, and March. That background is relevant here because it places the company firmly in the precision-rifle and premium-optics segment, where repeatable machining and dependable fit are more important than cosmetic design. The Monomount system reflects that same approach, with a focus on rigid one-piece construction for serious rifle setups.
