The Marlin Model 60 is a legendary .22LR rifle, prized for its reliability and affordability. However, one common complaint among users is the relatively small feed throat, which can sometimes lead to feeding issues, especially with certain types of ammunition. This is where the Marlin Model 60 feed throat conversion kit comes in. This guide will delve into everything you need to know about these kits, helping you decide if one is right for your rifle and guiding you through the installation process.
Understanding the Need for a Feed Throat Conversion Kit
The Marlin Model 60's original feed throat design, while generally reliable, can be sensitive to variations in ammunition. Certain types of ammunition, particularly those with slightly oversized bullets or inconsistent casing dimensions, may experience feeding problems, resulting in jams or misfires. This can be frustrating during both target practice and hunting.
A feed throat conversion kit addresses this issue by enlarging the feed throat, allowing for a wider range of ammunition types to feed smoothly. This modification often leads to improved reliability and reduces the frequency of malfunctions. Think of it as a minor upgrade that can significantly enhance your shooting experience.
Common Problems Addressed by the Conversion Kit
- Feeding Jams: The most common problem is the rifle jamming due to the bullet catching on the original, narrower feed throat.
- Misfires: Poor feeding can sometimes lead to misfires as the round isn't properly aligned with the firing pin.
- Inconsistent Feeding: Even if the rifle fires, inconsistent feeding can disrupt accuracy and rhythm.
- Ammunition Limitations: The standard feed throat often restricts the types of ammunition you can reliably use.
Types of Marlin Model 60 Feed Throat Conversion Kits
While the core function remains the same (enlarging the feed throat), different kits offer various approaches and materials:
-
CNC Machined Kits: These are typically made from high-quality materials like steel or aluminum and are precisely machined for a perfect fit. They are often considered the highest quality option, offering superior durability and accuracy. Expect a higher price point for this increased precision and material quality.
-
Files and Dremel Kits: Some individuals choose to enlarge the feed throat manually using files and a Dremel tool. This method requires considerable skill and patience, and it's crucial to avoid damaging the receiver. This route is cheaper but significantly riskier. It's recommended only for experienced gunsmiths.
-
Pre-installed Barrels: Some companies offer complete barrels with an already-modified feed throat. Replacing the entire barrel provides a more comprehensive upgrade, addressing other potential performance limitations. It's a more permanent change.
Installing a Marlin Model 60 Feed Throat Conversion Kit (CNC Machined Kit Example)
Disclaimer: Working on firearms requires safety precautions and proper tools. If you are not comfortable working on firearms, consult a qualified gunsmith. Improper modifications can damage the rifle or create safety hazards.
Tools Required:
- Screwdrivers (appropriate size for action screws): Necessary to remove the action screws.
- Punch (brass or nylon preferred): For safely removing pins.
- Small Hammer: For gently tapping the punch.
- Gunsmithing Vice (optional but recommended): To securely hold the receiver during disassembly and reassembly.
- Appropriate Lubricant: To facilitate the assembly process and help reduce friction.
Steps:
- Safety First: Always unload and verify the rifle is unloaded before beginning any work.
- Disassembly: Carefully disassemble the rifle's action according to the manufacturer's instructions or a reputable guide. Take pictures throughout the process to aid in reassembly.
- Removal of Old Feed Throat: Remove the original feed throat using the appropriate tools. This often involves removing pins or screws.
- Installation of the New Feed Throat: Carefully install the new feed throat from the conversion kit, ensuring proper alignment and fit.
- Reassembly: Reassemble the rifle carefully, referencing the pictures taken during disassembly. Make sure all parts are correctly seated and tightened to the manufacturer's specifications.
- Testing: Thoroughly test the rifle with various types of ammunition to ensure smooth and reliable feeding.
(Note: Specific steps may vary slightly depending on the kit and model of Marlin Model 60.)
Potential Benefits of a Marlin Model 60 Feed Throat Conversion Kit
- Improved Reliability: The most significant benefit is the reduction in feeding jams and misfires.
- Wider Ammunition Compatibility: The ability to use a wider range of ammunition.
- Increased Accuracy: Consistent feeding can positively affect accuracy.
- Enhanced Shooting Experience: A reliable rifle leads to a more enjoyable shooting experience.
Potential Drawbacks
- Cost: Conversion kits, particularly the higher-quality CNC machined ones, can be relatively expensive.
- Installation Complexity: While some kits are easier to install than others, any modification of a firearm carries some risk.
- Warranty Concerns: Modifications to your firearm might void the manufacturer's warranty.
Conclusion
A Marlin Model 60 feed throat conversion kit can be a valuable upgrade for those experiencing feeding problems or seeking to enhance the versatility of their rifle. Before purchasing a kit, carefully weigh the potential benefits against the costs and risks. Always prioritize safety and consider seeking professional help if you are not comfortable performing the installation yourself. Thorough research and careful execution will ensure that this upgrade enhances, not detracts, from your shooting experience.
