Why Choose the SAKO/TIKKA OptiLock Base?

When shooting rimfire cartridges, a reliable base is critical to maintaining sight alignment and repeatable accuracy. The OptiLock system is engineered to lock the base in place with a patented tightening method that eliminates slippage, even after repeated firing. Its lightweight design ensures that the rifle’s balance remains unchanged, allowing for quicker target acquisition and smoother handling.

Whether you’re a competitive shooter, a seasoned hunter, or a weekend plinker, this base provides the confidence you need to focus on the shot rather than the equipment.

3. Tighten the ring until you feel a firm “click” indicating a locked position.
4. Mount your optic using the appropriate 1‑inch ring or tube.
