Tier-One Picatinny, Tikka M590

• Action-specific fit: This Tier-One Picatinny rail is made for the Tikka M590 and Tikka M595, giving a secure interface that matches the receiver correctly and helps maintain alignment between rifle and optic.
• Picatinny interface: A full Picatinny rail makes it easier to mount a wide range of riflescope rings and accessories, which is useful when changing optics or refining eye relief and mounting position.
• Aluminium construction: The aluminium body keeps weight under control while still providing the rigidity needed for a stable optic platform on a hunting or range rifle.
• Precision-machined design: Tier-One machines its rails on five-axis CNC machinery, which supports consistent tolerances and a clean fit that matters when repeatable zero and dependable mounting are priorities.
• Black protective finish: The black finish gives the rail a low-profile appearance and suits practical field use, pairing well with most rifles and optics without adding visual distraction.

About the Tier-One Picatinny Rails Series

Tier-One Picatinny Rails are the company’s dedicated base system for shooters who want a precise, firearm-specific way to mount optics on a broad range of rifle actions. The series covers numerous action patterns rather than relying on a one-size-fits-all approach, which is important for correct receiver fit, screw placement and long-term mounting stability. A defining feature of the range is that each rail is machined from round bar stock to its finished form in a single operation on five-axis CNC machinery, a manufacturing approach chosen to keep tolerances consistent.

Across the series, Tier-One uses 7075-T6 aluminium, balancing low weight with the strength expected from serious shooting accessories. The rails are also stated to exceed the criteria for the STANAG 4694 NATO metric upgrade to the Picatinny rail standard, which reflects their focus on dimensional consistency and dependable accessory fit. Depending on the rifle variant, the series is offered in 0-, 10- or 20-MOA configurations, so the range serves both straightforward hunting setups and rifles intended for longer-distance shooting where additional elevation can be useful.

About the Tier-One Picatinny, Tikka M590

The Tier-One Picatinny, Tikka M590 is a rifle-specific mounting base built for shooters using a Tikka M590 or Tikka M595 action and wanting the flexibility of a Picatinny interface. Its main advantage is practical rather than complicated: it converts the rifle into a platform that can accept a wide variety of scope rings and optic setups, making it easier to choose ring height, adjust eye relief and move between different riflescope configurations without being tied to a more limited mounting format.

Because this model is part of Tier-One’s precision-machined rail family, it is intended to provide a stable foundation between rifle and optic. That matters in the field and on the range, where a properly fitted base helps the scope stay secure under recoil and supports consistent zero retention over time. The aluminium construction keeps the rail light enough not to add unnecessary bulk to the rifle, while still offering the stiffness expected from a quality optic base.

Its black finish gives it a discreet appearance that suits both hunting optics and more target-oriented rifle builds. For owners of older Tikka actions, this rail is especially useful because it brings the rifle onto the widely used Picatinny standard, opening access to a much broader selection of modern rings, optics and rail-mounted accessories.

About Tier-One

Tier-One was incorporated in 2008 and is based in the United Kingdom. The company focuses on precision shooting accessories, including rifle scope mounts, moderators, bipods and related hardware. Its reputation in the mounting category is reinforced by the fact that it manufactures precision scope rings for Zeiss USA and has also produced original-equipment-manufacturer products for Blaser, Sauer, AI and March.

A key part of Tier-One’s identity is that it manufactures products in-house on its own five-axis CNC machines, giving the company direct control over machining quality and consistency. Among its better-known products is the Monomount, a one-piece rifle scope mounting system that reflects the brand’s emphasis on rigid, accurately machined interfaces between rifle and optic. That same engineering approach carries across its rails, rings and other shooting accessories.
