The Ruger M77 Mark II is a highly regarded bolt-action rifle known for its accuracy and reliability. However, many shooters find the factory trigger to be a bit heavy and gritty, hindering their precision and overall shooting experience. This article will delve into the Ruger M77 Mark II trigger, exploring its characteristics, common issues, upgrade options, and how to perform adjustments for improved performance.
Understanding the Ruger M77 Mark II Factory Trigger
The factory trigger on the Ruger M77 Mark II is a relatively simple design, often described as a two-stage trigger. While it's reliable, it's not known for its crispness or light pull weight. This can lead to less precise shots, particularly for those accustomed to lighter, more refined triggers. The average pull weight is around 5-7 pounds, which is considered quite heavy by many competitive and precision shooters. This heavier pull can contribute to flinching and inconsistent shot placement. The gritty feel is often due to friction in the trigger mechanism.
Common Issues with the Factory Trigger
-
Heavy Pull Weight: As mentioned, the high pull weight is a significant drawback for many users. This directly impacts accuracy and the overall shooting experience.
-
Gritty Feel: The factory trigger often feels gritty and inconsistent, creating an imprecise feel. This hinders the shooter's ability to make fine adjustments for precise shots.
-
Creep: Creep is the movement of the trigger before it breaks. Excess creep in the Ruger M77 Mark II's factory trigger is common, making it difficult to determine the precise moment of release.
-
Overtravel: Overtravel is the distance the trigger moves after the shot breaks. Excessive overtravel can also contribute to inconsistent shot placement.
Upgrading Your Ruger M77 Mark II Trigger
For those seeking significant improvement, replacing the factory trigger with an aftermarket option is a popular choice. Several reputable companies manufacture drop-in triggers specifically designed for the Ruger M77 Mark II. These upgrades often offer:
-
Lighter Pull Weight: Aftermarket triggers can significantly reduce pull weight, often down to 2-4 pounds, depending on the model and adjustment.
-
Crisper Break: They typically provide a much crisper, cleaner break, eliminating the gritty feel and creep.
-
Adjustable Pull Weight and Overtravel: Many aftermarket triggers allow for adjustments to the pull weight and overtravel, allowing shooters to customize the trigger to their preferences.
Popular Aftermarket Trigger Options:
| Manufacturer | Model | Features | Price Range (USD) |
|---|---|---|---|
| Timney | Ruger M77 Trigger | Lightweight, crisp break, adjustable | $150 - $250 |
| Canjar | Various Models | Highly adjustable, known for precision | $200 - $350 |
| Rifle Basix | Various Models | Reliable, affordable, various adjustment options | $100 - $175 |
Note: Installing an aftermarket trigger often requires gunsmithing skills or experience. If you are not comfortable performing the installation yourself, it is crucial to have a qualified gunsmith do the work. Improper installation can damage the rifle or create safety hazards.
Adjusting the Factory Ruger M77 Mark II Trigger (Limited Adjustments)
While replacing the trigger offers the most significant improvement, some minor adjustments can be made to the factory trigger. However, these adjustments are limited and may not solve all issues. Improper adjustments can negatively impact trigger safety and reliability. Proceed with caution, and consult a gunsmith if uncertain.
Caution: Always ensure the rifle is unloaded and clear before attempting any adjustments.
Potential Adjustments
-
Overtravel Adjustment (Limited): Some Ruger M77 Mark II models may have a small screw that can slightly limit overtravel. Consult your owner's manual for specific instructions, as this is not always present.
-
Professional Gunsmithing: For more extensive adjustments, such as reducing pull weight, it is highly recommended to seek the expertise of a qualified gunsmith. Attempting to drastically alter the trigger mechanism without the proper knowledge and tools can lead to serious issues.
Conclusion: Improving Your Ruger M77 Mark II Shooting Experience
The factory trigger on the Ruger M77 Mark II can be a limiting factor for many shooters. Understanding its characteristics and limitations allows for informed decisions regarding upgrades or adjustments. While minor adjustments are possible, installing an aftermarket trigger often provides the most substantial improvement in trigger feel, pull weight, and overall shooting accuracy. Always prioritize safety and consult a professional if you are unsure about any modifications. Remember to always practice safe gun handling procedures.
