Maintaining your AR-15 rifle involves more than just cleaning; proper lubrication is crucial for ensuring smooth operation, extending the lifespan of your firearm, and maintaining accuracy. This guide will walk you through the process of lubricating your AR-15, covering the best lubricants, application techniques, and areas that require special attention.
Choosing the Right Lubricant for Your AR-15
Not all lubricants are created equal. The best lubricant for your AR-15 will depend on several factors, including the environment you'll be operating in and the type of shooting you'll be doing. Here's a breakdown of common options:
Types of AR-15 Lubricants:
-
Gun Oil: This is the most common type of lubricant for firearms. Look for oils specifically designed for firearms, as they are formulated to resist gumming and fouling. Common brands include CLP (Cleaner, Lubricant, Preservative) products and specialized gun oils.
-
Grease: Grease is thicker than oil and provides superior protection against wear and corrosion, particularly in harsh conditions or for long-term storage. It's best applied to areas that experience high friction and pressure, but shouldn't be used liberally.
-
Dry Lubricants: These are often used in conjunction with oil or grease, especially in extremely dirty environments. They can help reduce friction and prevent fouling.
Important Considerations: Avoid using motor oil, WD-40, or other household lubricants in your AR-15. These products can damage your firearm's components and potentially lead to malfunctions.
Where to Apply Lubricant on Your AR-15
Proper lubrication involves strategically applying lubricant to key areas that experience the most friction and stress. Here's a detailed breakdown:
Key Lubrication Points:
-
Bolt Carrier Group (BCG): This is arguably the most important area to lubricate. Apply a thin layer of lubricant to the rails of the BCG, ensuring they move smoothly within the upper receiver. Pay particular attention to the cam pin and the bolt lugs.
-
Gas Key: This area experiences high pressure and heat. Apply a small amount of lubricant to the gas key screws to prevent them from loosening or seizing.
-
Firing Pin: Apply a very small amount of lubricant to the firing pin, avoiding excessive lubrication which can cause malfunctions.
-
Buffer Tube: Lubricate the buffer and the inside of the buffer tube.
-
Trigger Mechanism: A small amount of lubricant on the trigger components can improve smoothness and reliability, but avoid over-lubricating as this can attract dirt and grit.
-
Magazine: While not directly part of the firearm's mechanism, lubricating the magazine rails can ensure smooth feeding.
The Lubrication Process: Step-by-Step
-
Clean your AR-15 thoroughly: Before lubricating, ensure your firearm is completely clean and free of any dirt, debris, or residue.
-
Apply lubricant sparingly: Use only a small amount of lubricant; a little goes a long way. Excessive lubrication can attract dirt and cause malfunctions.
-
Focus on key areas: Concentrate your lubrication efforts on the areas mentioned above.
-
Wipe away excess lubricant: After applying the lubricant, wipe away any excess using a clean patch. Avoid leaving pools of lubricant anywhere.
-
Cycle the action: After lubrication, cycle the action several times to distribute the lubricant evenly.
-
Inspect for proper function: After lubricating, test-fire your weapon under controlled and safe conditions to check for any issues.
Maintaining Your AR-15's Lubrication
Regular lubrication is key to maintaining your AR-15's optimal performance. The frequency of lubrication will depend on several factors, including the environment, the frequency of use, and the type of lubricant used. As a general rule, it’s good practice to re-lubricate your AR-15 after every shooting session or at least every few hundred rounds. Always inspect your firearm and reapply lubricant as needed.
Remember, safety is paramount. Always handle firearms responsibly and follow all applicable safety regulations. This guide provides general information; always consult your firearm's owner's manual for specific recommendations.
