Adjusting Trigger Pull Weight
The Sako 85's set trigger system is renowned for its crisp, predictable break, but sometimes you might want to fine-tune the trigger pull weight to better suit your shooting style or preferences. Adjusting the trigger pull weight on a Sako 85 involves a precise process that requires attention to detail and a basic understanding of the rifle's trigger mechanism. Before beginning, ensure you have the necessary tools, such as a torque wrench, screwdrivers, and a trigger pull gauge, to measure and adjust the trigger accurately.
To start adjusting the trigger pull weight, first ensure the rifle is unloaded and the safety is engaged. Remove the stock to access the trigger assembly. The Sako 85's trigger system typically features two screws: one for the first stage (or "set" stage) and one for the second stage (the actual firing stage). The first stage screw controls the weight required to "set" the trigger, while the second stage screw adjusts the final pull weight needed to discharge the rifle. Begin by identifying these screws, usually located on the trigger housing, and note their initial positions.
To adjust the second stage pull weight, use a torque wrench to turn the corresponding screw. Tightening this screw will increase the trigger pull weight, while loosening it will decrease the weight. Make small, incremental adjustments, such as 1/8 to 1/4 turn at a time, and test the trigger pull weight after each adjustment using a trigger pull gauge. This ensures you achieve the desired weight without over-adjusting. Remember, the goal is to find a balance between a light, crisp trigger and a weight that ensures safe operation.
If you wish to adjust the first stage weight (the "set" stage), locate the appropriate screw and follow a similar process. This adjustment affects how much pressure is needed to prepare the trigger for the final break. Be cautious when adjusting the first stage, as setting it too light can make the trigger more sensitive. Always test the trigger after each adjustment to ensure it functions reliably and safely. Once you’ve achieved the desired pull weight for both stages, reassemble the rifle, ensuring all components are securely tightened to the manufacturer’s specifications.
Finally, test the rifle’s trigger in a controlled environment, such as a shooting range, to ensure it performs as expected. Keep in mind that improper adjustments can affect the rifle’s safety and accuracy, so if you’re unsure, consult a professional gunsmith. Adjusting the trigger pull weight on a Sako 85 is a straightforward process when done carefully, allowing you to customize the rifle to your specific needs while maintaining its exceptional performance.

Safety Mechanisms in Set Triggers
The Sako 85's set trigger system is renowned for its crisp, lightweight pull, but it's crucial to understand the safety mechanisms integrated into this design. Unlike a standard single-stage trigger, the Sako 85's set trigger operates in two stages. The first stage is a light, adjustable pull that "sets" the trigger, reducing the weight required for the second stage. This second stage is an extremely light, almost imperceptible pull that releases the sear and fires the rifle. While this system offers exceptional precision, it demands careful consideration of safety features to prevent accidental discharges.
Safety in the Set Position:
The primary safety mechanism in the Sako 85's set trigger is its inherent design. When the trigger is in the "set" position, the sear is held in a precariously balanced state, requiring minimal force to release. However, the trigger blade itself is designed with a slight upward angle in this position. This angle acts as a passive safety, requiring a deliberate, straight rearward pull to activate the second stage. This design minimizes the risk of accidental discharge from bumping or snagging the trigger.
Manual Safety Integration:
The Sako 85's manual safety lever plays a crucial role in set trigger safety. When engaged, the manual safety physically blocks the sear from moving, preventing the trigger from releasing the firing pin, regardless of whether the trigger is set or not. This provides an additional layer of protection against accidental discharges, especially during handling or transportation. It's imperative to always engage the manual safety when the rifle is not in use, even if the trigger is not set.
Trigger Weight Adjustment and Safety:
Adjusting the set trigger weight on a Sako 85 requires careful attention to safety. The adjustment screw allows for fine-tuning of both the set and release weights. While a lighter trigger pull can enhance accuracy, it also increases the risk of accidental discharge. It's crucial to find a balance between a light, crisp pull and a weight that still requires deliberate, conscious effort to activate. Always make incremental adjustments and test the trigger pull with the rifle unloaded and pointed in a safe direction.
Training and Responsible Use:
Ultimately, the safest set trigger is one operated by a trained and responsible shooter. Familiarize yourself thoroughly with the Sako 85's trigger system, practicing dry firing (with the rifle unloaded and the manual safety engaged) to develop muscle memory and a consistent trigger pull. Always maintain proper trigger discipline, keeping your finger outside the trigger guard until ready to shoot. Remember, the set trigger's light pull demands heightened awareness and respect for firearm safety principles. By understanding the safety mechanisms integrated into the Sako 85's set trigger and practicing responsible gun handling, shooters can confidently utilize this precision-enhancing feature while minimizing risk.
