Maintaining your AR-15 rifle is crucial for its longevity and reliable performance. Proper lubrication is key, preventing wear and tear and ensuring smooth operation. This guide will walk you through the best practices for oiling your AR-15, covering what type of oil to use, where to apply it, and how often to lubricate.
Choosing the Right Oil for Your AR-15
Not all oils are created equal. Using the wrong type can lead to malfunctions or even damage your firearm. You want an oil specifically designed for firearms, offering excellent protection against friction and corrosion, while resisting gumming up in high-heat situations. Look for oils that are:
- Thin: Too thick an oil can hinder movement of internal parts.
- High-quality: Avoid cheap oils that might break down quickly.
- CLP (Cleaner, Lubricant, Protectant): Many gun owners prefer CLP oils for their versatility. They clean, lubricate, and protect all in one.
Avoid: Motor oil, WD-40, and other non-firearm-specific lubricants. These can attract dirt, gum up your weapon's internal mechanisms, and damage delicate parts.
Where to Apply Oil on Your AR-15
Proper oil application focuses on points of friction and wear. Here's a detailed breakdown:
Key Areas Requiring Lubrication:
- Bolt Carrier Group (BCG): This is arguably the most crucial area. Focus on the bolt lugs, cam pin, and the rails of the BCG. A light coating is sufficient.
- Receiver Extension (Buffer Tube): Apply a small amount of oil to the buffer tube where it interacts with the buffer.
- Gas Key: This area experiences significant heat and friction. Apply a thin layer of oil to the gas key and its surrounding area.
- Firing Pin: A drop or two of oil on the firing pin will ensure smooth operation.
- Trigger Group: While not requiring heavy lubrication, a very light oiling of the trigger pins and sear can contribute to smoother function.
Areas to Avoid Over-Oiling:
- Barrel: Avoid excessive oiling of the barrel. Excess oil can attract fouling and lead to malfunctions.
- Magwell: While keeping the magazine clean is important, the magwell itself doesn't require lubrication.
- Gas Rings: These require less lubrication than often thought. Over-oiling can lead to carbon buildup.
How Often to Oil Your AR-15
The frequency of oiling depends on several factors, including the shooting environment and frequency of use. As a general rule:
- After each shooting session: Clean and re-oil your AR-15 after every use. This removes built-up residue and prevents corrosion.
- Before long-term storage: Apply a protective layer of oil before storing your rifle for extended periods.
- Regular inspection: Periodically inspect your rifle for signs of wear or excessive oil buildup. Adjust your oiling routine as needed.
Cleaning Your AR-15 Before Oiling
Before oiling, thoroughly clean your AR-15. Removing dirt, carbon, and other debris is essential for effective lubrication. Use a quality gun cleaning kit and follow manufacturer guidelines for disassembly and cleaning.
Conclusion
Proper oiling is vital for your AR-15's performance and longevity. By choosing the right oil, focusing on key lubrication points, and cleaning your weapon regularly, you'll ensure smooth operation and years of reliable service. Remember, less is often more when it comes to oiling – a thin, even coat is always preferable to excessive lubrication. Consult your owner's manual for specific recommendations and always practice safe gun handling.
