The Marlin Model 60 is a legendary .22 rifle, known for its reliability and affordability. However, like any firearm, it can experience issues, and one common problem area is the feed throat. This in-depth guide will explore the Marlin Model 60 feed throat, covering troubleshooting common problems, performing maintenance, and offering tips for keeping your rifle running smoothly.
Understanding the Marlin Model 60 Feed Throat
The feed throat is the crucial part of your Marlin Model 60's action responsible for guiding the cartridges from the magazine into the chamber. A smooth, properly functioning feed throat is essential for reliable feeding and prevents malfunctions like stovepipes, failure to feed, and double feeds. It's a relatively simple mechanism, but understanding its components and how they work together is key to effective troubleshooting and maintenance.
Components of the Feed Throat
The Marlin Model 60 feed throat primarily consists of the following:
- The Magazine: The magazine itself plays a crucial role in feeding. A damaged or improperly loaded magazine can lead to feed issues.
- The Feed Ramp: This angled surface guides the cartridges smoothly from the magazine into the receiver. A damaged or rough feed ramp is a common cause of feeding problems.
- The Bolt: The bolt interacts directly with the cartridge as it's fed into the chamber. A damaged or improperly lubricated bolt can also contribute to feeding issues.
- The Ejector: While not directly part of the feed throat, the ejector's proper function is crucial for reliable cycling and removing spent cartridges.
Common Marlin Model 60 Feed Throat Problems
Several issues can affect the feed throat, leading to malfunctions. These problems are often related to wear and tear, improper cleaning, or ammunition type.
1. Failure to Feed
This is the most common problem, where the bolt fails to pick up a cartridge from the magazine. Causes can include:
- Dirty or damaged feed ramp: Buildup of debris or damage to the feed ramp can impede smooth cartridge movement.
- Bent or damaged magazine: A bent or damaged magazine can prevent cartridges from aligning properly.
- Weak magazine spring: A weak spring can fail to push cartridges up into the feed ramp.
- Improper ammunition: Using ammunition that is too short or too long can lead to feeding problems.
2. Stovepipes
A stovepipe occurs when the cartridge is partially extracted from the magazine but gets stuck above the chamber. This is often due to:
- Dirty or damaged feed ramp: Similar to failure to feed, a rough or dirty ramp can cause cartridges to jam.
- Excessive lubrication: Too much lubricant can cause cartridges to stick.
- Improper magazine alignment: The magazine may not be seated correctly.
3. Double Feeds
A double feed happens when two cartridges attempt to enter the chamber simultaneously. This is typically caused by:
- Damaged or worn bolt: A damaged bolt may not fully chamber the first cartridge.
- Faulty magazine: A damaged magazine spring or follower can cause multiple cartridges to be pushed into the action.
Troubleshooting and Maintenance of the Marlin Model 60 Feed Throat
Addressing feed throat issues usually involves a combination of cleaning, inspection, and potential part replacement.
1. Thorough Cleaning
Regular cleaning is crucial. Use a gun cleaning kit and follow these steps:
- Disassemble: Carefully disassemble the rifle, following the manufacturer's instructions.
- Clean the feed ramp: Use a bore brush and solvent to remove all debris from the feed ramp.
- Clean the bolt: Clean the bolt thoroughly, paying attention to the areas that contact the cartridges.
- Clean the magazine: Clean and inspect the magazine for damage or wear. Replace if necessary.
2. Inspection
After cleaning, carefully inspect all components for damage. Look for:
- Bent or damaged feed ramp: Straighten minor bends or replace the ramp if severely damaged.
- Wear on the bolt: Check for excessive wear or damage to the bolt face or extractor.
- Damage to the magazine: Replace a bent or broken magazine.
3. Lubrication
Use a high-quality gun lubricant to lubricate the moving parts of the action, including the bolt and feed ramp. Avoid over-lubrication, as it can cause issues.
4. Ammunition Selection
Experiment with different types and brands of ammunition to see if feeding problems are related to the ammunition itself.
Advanced Troubleshooting: When Simple Solutions Fail
If cleaning and inspection don't resolve feeding problems, consider these:
- Professional Gunsmith: A qualified gunsmith can diagnose and repair more complex issues.
- Part Replacement: Replace damaged or worn components such as the feed ramp, bolt, or magazine.
- Action Tuning: Advanced tuning by a gunsmith may be necessary in extreme cases.
Maintaining Your Marlin Model 60 Feed Throat
