Maintaining your AR-15 rifle involves more than just keeping it clean; proper lubrication is crucial for ensuring smooth operation, extending its lifespan, and preventing malfunctions. Knowing where to apply lubricant is just as important as what type of lubricant to use. This guide details the key lubrication points on your AR-15, providing a clear and comprehensive approach to maintaining peak performance.
Key Lubrication Points on Your AR-15
The AR-15 platform has several critical areas that require regular lubrication. Focusing on these points will significantly improve the reliability and longevity of your firearm.
1. Bolt Carrier Group (BCG):
The BCG is the heart of your AR-15's operation. Proper lubrication here is paramount. Focus on these specific areas:
- Bolt Face: A small amount of lubricant applied to the bolt face helps prevent galling and ensures smooth cycling.
- Cam Pin: This small pin facilitates the BCG's reciprocation. A tiny drop of lubricant here will greatly reduce friction.
- Keyway: Lubricate the keyway where the bolt rides on the carrier.
- Carrier Rails: Apply lubricant to the rails that contact the upper receiver. Ensure even coverage along the entire length of the rails. This is a critical lubrication point for smooth operation.
2. Upper Receiver:
The upper receiver houses the BCG and plays a vital role in the rifle's operation. Lubricate these areas:
- Extension Rails: These rails guide the BCG and need regular lubrication to prevent wear.
- Charging Handle: Applying a small amount of lubricant to the charging handle will reduce friction and ensure smoother operation.
3. Lower Receiver:
While the lower receiver doesn't directly interact with the moving parts as much as the upper, some lubrication is still beneficial:
- Hammer and Trigger Pins: Applying a small amount of lubricant to these pins helps ensure smooth operation.
4. Buffer Tube and Spring:
The buffer system absorbs recoil. While not requiring heavy lubrication, a light coating on the buffer spring can help reduce friction and extend its lifespan.
What Type of Lubricant to Use?
Choosing the right lubricant is as important as knowing where to apply it. Use a high-quality gun oil specifically designed for firearms. Avoid using general-purpose lubricants or oils as they may not withstand the high temperatures and pressures found within a firearm.
Frequency of Lubrication
The frequency of lubrication depends on several factors, including the environment in which you use your rifle, the intensity of use, and the type of lubricant used. Regular cleaning and lubrication after each shooting session is highly recommended. If you are in a particularly dusty or dirty environment, you might need to lube more often.
A Note on Over-Lubrication
While proper lubrication is essential, over-lubrication can be detrimental. Excess lubricant can attract dirt and debris, leading to fouling and malfunctions. Apply only a small amount to each lubrication point.
Conclusion
Proper lubrication of your AR-15 is critical for reliable function and longevity. By focusing on the key areas outlined above and using a high-quality gun lubricant, you can ensure your rifle operates smoothly and efficiently for years to come. Remember, regular cleaning and maintenance are key components of responsible gun ownership.
