Understanding the Marlin Model 60 Trigger Mechanism
The Components
The Marlin Model 60 trigger system, at its core, is a straightforward mechanical process. It’s comprised of several key components working in harmony: the trigger itself, the sear, the spring (or springs), and the hammer. When you pull the trigger, it interacts with the sear. The sear, in turn, holds the hammer in a cocked position, ready to strike the firing pin. The hammer is under tension from the mainspring, which provides the energy to ignite the cartridge. The trigger pull itself is the force required to overcome the sear’s resistance and release the hammer. This resistance is heavily influenced by the design of the trigger, the sear, and the spring pressure.
Common Issues
The common issues in the factory trigger are frequently attributed to a few factors. The trigger pull weight often feels heavier than desired due to friction within the mechanism and the spring’s force. The grittiness is usually a result of imperfections, burrs, or rough surfaces on the trigger and sear. These imperfections cause the trigger pull to feel uneven, and the release is not crisp. Over time, wear and tear can exacerbate these issues, making the trigger feel even worse. The goal of any **Marlin Model 60 trigger upgrade** is to address these pain points.
Choosing Your Trigger Upgrade Options
The good news is that there are several options available to improve your Marlin Model 60’s trigger. The best choice for you will depend on your skill level, budget, and desired results. Let’s explore the various possibilities:
Trigger Springs
One popular, budget-friendly route involves aftermarket trigger springs. These springs, usually made from lighter materials, replace the factory spring and reduce the trigger pull weight. This is a simple and relatively inexpensive upgrade, often requiring only basic tools and mechanical aptitude. Installation is typically straightforward, making it a great starting point for beginners.
Complete Trigger Kits
For those seeking a more comprehensive approach, complete trigger kits are available. These kits usually include a lighter trigger spring, an improved sear, and sometimes a new trigger. A complete trigger kit often delivers a more noticeable improvement in trigger pull weight and smoothness than just a spring replacement. Installation may require slightly more mechanical skill, but the results can be well worth the effort.
Aftermarket Triggers
Another option is to opt for an aftermarket trigger. These triggers are often made from higher-quality materials, are precision-engineered, and are designed for a much better feel and break than the factory one. They can deliver significant improvements in both trigger pull weight and the overall feel of the trigger, resulting in a crisp, clean break.
DIY Polishing
Finally, for the adventurous gunsmith, there is the do-it-yourself polishing approach. This involves disassembling the trigger mechanism and carefully polishing the contact surfaces of the trigger, sear, and other related parts. This process can significantly reduce friction and improve trigger smoothness. However, it requires more skill, patience, and the right tools and polishing compounds.
The choice depends on your personal needs. If you are budget-conscious and want a quick improvement, a lighter trigger spring is an excellent choice. If you desire a more dramatic change, consider a complete trigger kit or an aftermarket trigger. DIY polishing is the most involved but can deliver impressive results for those with the skills and patience.
Installation Instructions and Techniques
Before you begin any trigger upgrade, safety is paramount. Always ensure your Marlin Model 60 is unloaded before starting any work. Double-check that the chamber is empty and that there are no rounds in the magazine. Clear your work area of any ammunition. Put on safety glasses.
Here’s a general guide, but always refer to the specific instructions provided with your chosen upgrade kit.
Tools and Materials Needed
- Screwdrivers (various sizes, including a small flathead for pin removal)
- Punch set (roll pin punch and a pin punch)
- Gunsmith hammer (or a small, soft-faced hammer)
- Cleaning solvent or degreaser
- Lubricant (gun oil or grease)
- Bench block (optional, but highly recommended)
- Safety glasses
- The upgrade kit or parts of your choice
Step-by-Step Guide
- Disassembly: Start by safely field stripping your Marlin Model 60. This usually involves removing the barrel band screw, the takedown screw, and separating the stock from the receiver. Refer to your owner’s manual for specific field stripping instructions.
- Trigger Removal: Once the receiver is separated from the stock, you can begin to work on the trigger mechanism. Locate the pins that hold the trigger assembly in place. Use the punch set to carefully tap out these pins. Work slowly and ensure you don’t damage any of the surrounding parts. Once the pins are removed, the trigger assembly should come out.
- Component Removal: Carefully remove the factory trigger components (trigger, sear, spring) from the receiver. Note their positions and how they interact for reassembly purposes.
- Installation of Chosen Upgrade Parts: Refer to the specific instructions included with your chosen upgrade kit. This will vary depending on the type of upgrade. For trigger springs, simply replace the factory spring with the new one. For a complete trigger kit, you’ll need to install the new trigger, sear, and spring. Follow the instructions meticulously to ensure proper fit and function.
- Reassembly: Once the new components are installed, carefully reassemble the trigger mechanism into the receiver. Align the holes and reinsert the pins, using the punch set to drive them back in.
- Function Testing: Before you do anything else, carefully check the function of the trigger. Ensure it cocks and releases the hammer safely and properly. Test the safety mechanism to make sure it engages and disengages as intended. This can be achieved by dry firing the rifle, after verifying it’s unloaded.
- Adjustments: Some aftermarket trigger kits or triggers may include adjustment screws to fine-tune the trigger pull. Follow the kit’s instructions to make any necessary adjustments, keeping safety in mind.
Remember that the specific steps may vary slightly depending on the particular upgrade you’ve chosen. Always consult the manufacturer’s instructions and consider seeking professional help if you’re not comfortable with any part of the process.
Post-Installation and Troubleshooting
After completing the **Marlin Model 60 trigger upgrade**, the real test is in the shooting. Test the trigger in a controlled environment. A range is the best place to gauge the difference in the trigger.
If, however, you encounter any issues, don’t panic. Here are some common problems and how to troubleshoot them:
Light Primer Strikes
This can happen if the new spring isn’t providing enough force to reliably ignite the primer. Try switching back to the factory mainspring or consult a gunsmith.
Failure to Feed
This may be an indication that the new trigger isn’t cycling the action correctly, preventing the rifle from loading a round. Ensure all components are installed properly and that there are no obstructions in the action.
Failure to Eject
The trigger may not be causing an ejection problem but if it happens after the trigger upgrade, check the new springs’ or triggers’ connection to the other components and make sure the ejection mechanism is functioning properly.
Remember to always prioritize safety when working on firearms. If you’re unsure about any aspect of the process, seek guidance from a qualified gunsmith.
The DIY Polishing Option (Detailed)
If you’re keen on improving the trigger pull further, you can consider the do-it-yourself polishing approach. This involves careful polishing of the trigger components to reduce friction and improve smoothness.
Materials Needed
- Polishing compounds (fine grit to ultra-fine)
- Small polishing tools (Q-tips, cotton swabs, felt bobs, etc.)
- Vise or small clamp
- Cleaning solvent or degreaser
Detailed Polishing Steps
- Disassemble: You’ll need to disassemble the trigger components, just like you did for the trigger upgrade.
- Clean and Inspect: Thoroughly clean the trigger, sear, and other components with a solvent or degreaser. Inspect the surfaces for any burrs, rough spots, or imperfections.
- Polishing: Start with a fine grit polishing compound and gently polish the contact surfaces of the trigger and sear. Apply a small amount of compound to a polishing tool and work it on the surface using small, circular motions. The goal is to remove any roughness and smooth the surfaces.
- Progressive Grits: After using a fine grit, move to finer and finer grits, working until the surfaces become very smooth and polished. Repeat this on all areas that have contact with other components.
- Clean: After polishing each component, clean it thoroughly to remove any polishing compound residue.
- Reassemble and Test: Carefully reassemble the trigger mechanism and test its function.
