The Ruger M77 Mark II is a renowned bolt-action rifle appreciated for its accuracy and reliability. However, many shooters find the factory trigger to be somewhat heavy and gritty, hindering their precision and overall shooting experience. This guide delves into the Ruger M77 Mark II trigger, exploring its intricacies, potential upgrades, and adjustments you can make to enhance your shooting performance.
Understanding the Ruger M77 Mark II Factory Trigger
The standard Ruger M77 Mark II trigger is a two-stage design. This means the trigger pull is broken into two distinct phases: the first stage is a slight take-up, followed by a second stage where the rifle fires. While this two-stage system is designed for safety and consistency, the factory setup often feels heavy (around 5-7 pounds), with a noticeable amount of creep before the break. This can negatively impact accuracy, especially for precision shooting. The gritty feeling often stems from friction in the mechanism.
Trigger Adjustments: What You Can Do Yourself
Before considering an aftermarket trigger, explore the adjustments possible within the factory trigger mechanism. Important Note: Always prioritize safety when working on firearms. If you are not comfortable working on firearm mechanisms, seek the assistance of a qualified gunsmith.
Over-travel Adjustment:
Excessive trigger over-travel (how far the trigger travels after the shot breaks) can affect accuracy and feel. Many Ruger M77 Mark II models allow for over-travel adjustment. Consult your owner's manual for specific instructions, but generally, this involves adjusting a screw located within the trigger group. Reducing over-travel can create a crisper, more consistent trigger pull.
Trigger Pull Weight Adjustment (Limited):
While not as extensive as with some other rifles, some Ruger M77 Mark II models offer minor adjustments to the trigger pull weight. Again, consult your owner's manual, as the method varies slightly depending on the model and year of manufacture. Keep in mind that any adjustments should be approached cautiously to maintain a safe and reliable trigger function.
Upgrading Your Ruger M77 Mark II Trigger: Aftermarket Options
If adjustments aren't sufficient to achieve your desired trigger pull weight and feel, exploring aftermarket triggers is a viable option. Several reputable manufacturers offer drop-in triggers specifically designed for the Ruger M77 Mark II. These typically provide a lighter, crisper, and more consistent trigger pull than the factory unit. Some popular choices include:
Timney Triggers:
Known for their high-quality construction and smooth performance, Timney triggers are a frequent upgrade for many rifles, including the Ruger M77 Mark II. They are typically adjustable for both pull weight and over-travel.
Canjar Triggers:
Canjar triggers are another reputable option often praised for their exceptional craftsmanship and precision. Their adjustable features allow for fine-tuning to suit individual preferences.
Choosing the Right Upgrade: Factors to Consider
When selecting an aftermarket trigger, consider the following:
- Your Budget: Prices vary considerably across different brands and models.
- Desired Trigger Pull Weight: Determine your ideal trigger pull weight for your shooting style and skill level. Remember to prioritize safety—an excessively light trigger can be dangerous.
- Adjustability: Consider whether you want a trigger with adjustable pull weight and over-travel.
- Installation Difficulty: Some drop-in triggers are easier to install than others. Check the manufacturer's instructions and consider your mechanical aptitude.
Conclusion: Enhancing Your Ruger M77 Mark II Shooting Experience
Whether you choose to adjust the factory trigger or opt for an aftermarket upgrade, improving your Ruger M77 Mark II's trigger is a worthwhile investment. A lighter, crisper trigger will significantly enhance accuracy and overall shooting enjoyment. Remember to always prioritize safety and consult your owner's manual or a qualified gunsmith if you have any questions or concerns. Careful attention to detail will lead to a more precise and satisfying shooting experience with your Ruger M77 Mark II.
