Maintaining your AR-15 rifle involves more than just cleaning; proper lubrication is crucial for reliable function and extended lifespan. Knowing where to apply lubricant is just as important as what type of lubricant to use. This guide will cover the key lubrication points on your AR-15, ensuring your firearm runs smoothly and efficiently.
Key Areas Requiring Lubrication
The AR-15 platform has several critical points that benefit significantly from proper lubrication. Neglecting these areas can lead to malfunctions, increased wear, and ultimately, damage to your weapon. Remember to always use a high-quality gun lubricant designed for the rigors of firearm operation.
1. Bolt Carrier Group (BCG):
This is arguably the most important area to lubricate. The BCG is subjected to intense friction and heat during operation. Focus on these specific points within the BCG:
- Bolt Rails: Apply a thin layer of lubricant to the rails where the bolt rides within the upper receiver. This reduces friction and ensures smooth cycling.
- Cam Pin: A small amount of lubricant on the cam pin helps smooth its action within the bolt carrier.
- Bolt Face: A tiny amount of lubricant on the bolt face helps prevent fouling and corrosion. Avoid excessive lubrication here as it can attract debris.
2. Upper Receiver:
The upper receiver houses the BCG and is subjected to significant friction as the bolt moves. Lubricate the following areas:
- Receiver Extension (Buffer Tube): The buffer tube interacts with the buffer and spring, so lubrication here reduces friction and wear.
- Areas of Contact: Pay attention to areas where the BCG interacts with the receiver – any points of rubbing contact will benefit from a light coating of lubricant.
3. Lower Receiver:
While the lower receiver doesn't experience as much friction as the upper, there are still points to address:
- Hammer and Trigger Pins: A very small amount of lubricant on these pins ensures smooth operation of the trigger group. Avoid excessive lubricant here as it can attract debris and cause malfunctions.
- Magazine Catch: Keep this area lubricated to ensure smooth magazine insertion and removal.
4. Gas System:
The gas system is responsible for cycling the BCG, and proper lubrication is critical.
- Gas Key: Lubricating the gas key ensures smooth gas impingement on the bolt.
- Gas Tube: While internal lubrication of the gas tube isn't always necessary, a light external wipe with lubricant can prevent corrosion.
Lubrication Techniques and Considerations:
- Less is More: Over-lubrication is counterproductive. It can attract dirt and grit, leading to malfunctions. Apply only a thin layer of lubricant.
- Clean Before Lubricating: Always clean your AR-15 thoroughly before lubricating. Removing dirt and debris prevents the lubricant from becoming abrasive.
- Type of Lubricant: Use a high-quality gun lubricant specifically formulated for firearms. CLP (Cleaner, Lubricant, Protectant) is a popular choice.
- Environmental Conditions: The climate can impact your lubrication needs. In extreme conditions (very hot or cold), you may need to adjust the amount of lubricant accordingly.
By following this guide and paying close attention to the lubrication points outlined, you’ll significantly improve the reliability and longevity of your AR-15 rifle. Regular maintenance, including proper lubrication, is key to responsible firearm ownership. Remember to always consult your owner's manual for specific recommendations from the manufacturer.
