Why Choose the SAKO Optilock Base?
When you replace a standard base with the Optilock system, you are investing in a component that has been tested extensively in both competitive shooting and tactical environments. The base’s locking mechanism secures the receiver in a fixed position, eliminating the tiny movements that can cause a shift in point‑of‑impact. This results in a rifle that stays on target, shot after shot, even after repeated disassembly and reassembly.
Installation Overview
- Remove the existing receiver base following the Sako service manual instructions.
- Clean the receiver seat and ensure all threads are free of debris.
- Apply a thin layer of high‑temperature grease to the Optilock locking lugs (optional for smoother operation).
- Place the Optilock base onto the receiver, aligning the locking pins with the machined slots.
- Secure the base using the supplied set‑screws, tightening to the manufacturer‑specified torque.
- Re‑assemble the rifle and perform a functional check before re‑zeroing your optics.
