The Marlin Model 60 is a legendary .22LR rifle, known for its affordability, reliability, and accuracy. However, many shooters find the factory trigger to be somewhat gritty and heavy. This can significantly impact accuracy and overall shooting enjoyment. A trigger job can dramatically improve the feel and performance of your Model 60, making it a more precise and pleasant shooting experience. This guide provides a comprehensive overview of performing a Marlin Model 60 trigger job, covering various techniques and considerations.
Understanding the Marlin Model 60 Trigger Mechanism
Before diving into the specifics of a trigger job, it's crucial to understand the inner workings of the Model 60's trigger mechanism. This involves familiarizing yourself with the various components, including the sear, trigger, hammer, and disconnector. A thorough understanding of these parts and their interactions is essential for a safe and successful trigger job. Always prioritize safety and handle firearms responsibly.
Tools and Materials Needed
Performing a Marlin Model 60 trigger job requires specific tools and materials. These typically include:
- Gunsmithing Screwdrivers: A quality set of gunsmithing screwdrivers with various sizes and tip types is essential.
- Punch Set: A punch set with appropriately sized punches will be necessary for removing pins.
- Action Wrench (optional): While not strictly necessary for a basic trigger job, an action wrench can simplify the process.
- Stoner Gun Cleaning Kit: This type of kit includes various cleaning materials to prevent damage to the trigger mechanism during cleaning and reassembly.
- Fine-grit Sandpaper: Fine-grit sandpaper (e.g., 400-grit) can be used to smooth out rough surfaces.
- Gun Grease or Oil: A high-quality gun lubricant is essential for proper lubrication and functionality.
- Safety Glasses and Hearing Protection: Always wear appropriate safety gear when working with firearms.
- Magnifying Glass: A magnifying glass can aid in seeing small parts and details.
Types of Marlin Model 60 Trigger Jobs
There are several approaches to a Marlin Model 60 trigger job, ranging from simple polishing to more involved modifications.
1. Simple Polishing and Cleaning:
This is the least invasive method. It involves disassembling the trigger group, cleaning all parts thoroughly, and polishing any rough or burred surfaces with fine-grit sandpaper. This can noticeably improve the trigger's feel and reduce the creep.
2. Trigger Spring Modification:
A slightly more advanced approach involves modifying the trigger spring. This can reduce trigger pull weight, but requires careful consideration to avoid compromising the rifle's reliability and safety. Improper modification can lead to malfunctions or unsafe conditions.
3. Advanced Trigger Job:
This involves more significant modifications, such as stoning or polishing the sear engagement surfaces. This can result in a very crisp and light trigger pull, but it requires a high level of skill and precision and should only be attempted by experienced gunsmiths.
