- Over-Lubrication:
- Excess oil can attract dust, dirt, and carbon, leading to excessive buildup and potential malfunctions.
- In extreme cases, excess lubricant can seep into the trigger assembly, causing reliability issues.
- Over-lubed rifles tend to run dirty much faster, requiring more frequent cleaning.
- Under-Lubrication:
- A dry-running bolt carrier group (BCG) increases friction, leading to premature wear and cycling issues.
- Insufficient lubrication can cause failure-to-feed (FTF) and failure-to-extract (FTE) malfunctions, particularly in high-round-count sessions.
- Running an AR-15 dehydrated increases the risk of metal-on-metal contact, which can damage internal components over time.
Solution: Apply a thin lubricant layer to moving parts, particularly the BCG, cam pin, and charging handle, to ensure smooth operation without excessive buildup.
Using the Wrong Cleaning Solvents
Not all gun cleaning solvents are safe for use on an AR-15. Some can damage critical components, leading to premature wear or functional issues.
- Avoid Harsh Chemical Cleaners:
- Industrial degreasers and strong ammonia-based solvents can strip protective coatings from metal parts.
- Harsh chemicals can also degrade rubber O-rings and polymer components over time.
- Avoid Household Oils & Penetrants (e.g., WD-40):
- Products like WD-40 are not designed for firearm lubrication and can evaporate quickly, leaving behind gummy residue.
- These oils lack the high-temperature resistance needed for sustained firing sessions.
Solution: Use AR-15-specific solvents and CLP (Cleaner, Lubricant, Protectant) to break down carbon buildup without damaging metal finishes or polymer components.
Not Cleaning the Gas System and Buffer Tube
Many AR-15 owners focus on cleaning the barrel and bolt carrier group (BCG) but neglect other critical areas like the gas system and buffer tube.
- Neglecting the Gas System:
- The gas tube and gas block accumulate carbon over time, which can cause cycling issues and gas flow restrictions.
- Excess carbon buildup in the gas key on the BCG can reduce efficiency, leading to failure-to-cycle malfunctions.
- Ignoring the Buffer Tube & Spring:
- Dirt, grime, and moisture can collect in the buffer tube, affecting the smooth cycling of the buffer and buffer spring.
- A dirty or dry buffer system can lead to inconsistent recoil management and sluggish bolt movement.
Solution: Periodically inspect and clean the gas system and buffer assembly. While the gas tube rarely needs deep cleaning, ensure carbon deposits are removed from the gas key and gas block. You can lightly lubricate the buffer spring to prevent rust and provide smooth functioning.
By avoiding these common AR-15 cleaning mistakes, you can ensure consistent performance, reduced wear, and long-term reliability. A well-maintained rifle will serve you reliably, whether on the range, in competition, or for personal defense.
