Optilock Sako Long Base

• Steel base construction: The steel body gives the scope mounting system a rigid foundation that resists movement under recoil and helps the optic stay aligned over time.
• Long-action fit for selected Sako rifles: This long base is made for specific Sako actions and rifle models, giving a correct interface without improvised adapters or universal compromises.
• Optilock system compatibility: Designed to work within the Optilock mounting family, the base forms a stable platform for matching rings and supports a clean, rifle-specific installation.
• Low 8.00 mm base height: The modest base height helps keep the optic close to the bore, which supports a natural cheek weld and a more consistent shooting position.
• Purpose-built hunting and field use: A fixed base has no moving parts to loosen in normal use, making it a practical choice for rifles carried in rough weather and varied terrain.

About the Optilock Series

The Optilock series is Sako’s line of rifle scope mounts, bases, and rings, developed for shooters who want a rifle-specific mounting solution rather than a generic rail-and-ring combination. Within the Sako ecosystem, Optilock sits as the traditional mounting system for many hunting rifles, combining a close fit to the receiver with the strength needed for repeated field use. The range includes bases for compatible rifle interfaces as well as rings in different diameters and heights, so the system can be matched to both the rifle and the scope.

A defining feature of the series is the use of polymer inserts in Optilock rings. These inserts help distribute clamping force around the scope tube and reduce the risk of marking the optic during installation. Across the line, the design philosophy is straightforward: steel construction, secure engagement with the rifle, and a mounting height chosen to keep the optic practical in real shooting positions. For hunting rifles and traditional sporting setups, Optilock remains a system focused on durability, repeatable positioning, and compatibility with Sako and Tikka rifles.

About the Optilock Sako Long Base

The Optilock Sako Long Base is a fixed steel scope base made for selected Sako long and medium-long action rifles, including models from the Sako 75, Sako 85, classic L-series rifles, and the TRG-S M995 family. Its role is simple but important: it provides the correct foundation for mounting an optic on rifles that are often chosen for full-size hunting cartridges and longer receiver lengths. A model-specific base matters here because it supports proper ring placement and gives the scope a stable seat without relying on a one-size-fits-all solution.

The base is made from steel, which is well suited to hard field use and repeated recoil. That rigidity helps preserve alignment between rifle and optic, especially on rifles carried over long seasons or used with heavier calibers. The 8.00 mm BH height keeps the mounting platform relatively low, which helps maintain a sensible sight line and supports a more natural head position behind the scope. In practice, that can make the rifle quicker to shoulder and easier to shoot consistently from field positions.

As part of the Optilock mounting system, this long base is intended for shooters who prefer a traditional, rifle-specific setup with dependable mechanical fit. It suits hunting rifles where reliability, secure attachment, and a clean installation matter more than frequent reconfiguration.

About Optilock

Optilock is Sako’s line of rifle scope mounts, bases, and rings, created to give Sako and Tikka rifles a dedicated optics-mounting system. The range is built around practical fit and mechanical security, with bases offered for compatible rifle interfaces and rings available in different diameters and heights to suit various scopes. A notable part of the design is the use of polymer inserts around the scope tube, which help spread clamping force more evenly and reduce the chance of marking the optic during installation.

Across the line, steel construction is central to the concept, including versions machined from CrMo alloy or stainless steel. That focus reflects Optilock’s role as a traditional mounting solution for sporting and hunting rifles, where repeatable alignment, durability, and a close fit to the rifle matter more than modularity for its own sake.
