The Ruger AR-556, while generally considered a reliable and affordable AR-platform rifle, isn't immune to potential issues. Understanding these common problems and how to address them is crucial for any owner looking to maximize their firearm's performance and longevity. This guide provides a detailed look at frequently reported problems, their potential causes, and effective troubleshooting steps.
Common Ruger AR-556 Issues and Solutions
This section dives into some of the most commonly reported problems with the Ruger AR-556, offering practical solutions and preventative measures.
1. Failure to Extract/Eject (FTE/FTE)
Symptoms: Spent casings fail to fully extract from the chamber, leading to malfunctions. This can manifest as a stovepipe (casing partially ejected but stuck), a double feed (new round feeding on top of a stuck casing), or a complete failure to eject.
Potential Causes:
- Weak or improperly installed extractor: A broken or worn extractor spring or a poorly seated extractor can prevent proper casing extraction.
- Over-gassed system: Excessive gas pressure can slam the bolt back too forcefully, preventing complete extraction.
- Dirty or damaged chamber: Buildup of fouling in the chamber can hinder casing extraction.
- Improperly lubricated action: Insufficient lubrication can cause friction and impede cycling.
- Ammunition issues: Using ammunition with weak primers or inconsistent case dimensions can also contribute.
Troubleshooting:
- Inspect the extractor: Ensure it's properly installed and the spring is functioning correctly. Replace if necessary.
- Check gas system adjustments: If possible, adjust the gas block to reduce gas pressure. Consult your owner's manual for instructions.
- Clean the chamber thoroughly: Remove any debris or fouling from the chamber.
- Lubricate the action: Apply a suitable gun lubricant to moving parts.
- Try different ammunition: Test with different brands and types of ammunition to rule out ammunition as a cause.
2. Failure to Feed (FTF)
Symptoms: The rifle fails to properly feed a round from the magazine into the chamber.
Potential Causes:
- Magazine issues: Damaged or improperly functioning magazines are a common culprit.
- Improperly seated bolt carrier group (BCG): A slightly out-of-spec BCG can hinder feeding.
- Obstructions in the receiver: Debris or foreign objects can interfere with the feeding process.
- Bent feed ramps: Though less common, damaged feed ramps can cause feeding problems.
Troubleshooting:
- Try different magazines: Test with known good magazines to determine if the issue lies with the magazines.
- Check BCG seating: Ensure the BCG is correctly installed and properly lubricated.
- Inspect the receiver: Carefully examine the receiver for any obstructions.
- Check feed ramps (by a qualified gunsmith): Bent feed ramps typically require professional repair.
3. Bolt Carrier Group (BCG) Issues
Symptoms: Issues can range from FTE/FTF to excessive wear and tear on the BCG.
Potential Causes:
- Insufficient lubrication: Lack of proper lubrication leads to increased friction and wear.
- Use of incorrect ammunition: Using ammunition outside the rifle's specifications can stress the BCG.
- Improper cleaning and maintenance: Neglecting proper cleaning can cause fouling and wear.
Troubleshooting:
- Proper lubrication: Regularly lubricate the BCG with a high-quality gun lubricant.
- Inspect for wear: Check the BCG for signs of excessive wear and replace components as needed.
- Follow cleaning instructions: Adhere to the manufacturer's cleaning and maintenance recommendations.
4. Accuracy Problems
Symptoms: Inconsistent shot grouping and poor accuracy.
Potential Causes:
- Ammunition issues: Using inconsistent or low-quality ammunition will negatively impact accuracy.
- Improper sighting: An improperly zeroed optic or iron sights will lead to inaccurate shooting.
- Barrel condition: A damaged or fouled barrel will affect accuracy.
- Poor shooting technique: Improper shooting technique is a frequent cause of accuracy problems.
Troubleshooting:
- Use high-quality ammunition: Ensure you're using consistent and high-quality ammunition.
- Zero your sights properly: Properly zero your sights at your desired range.
- Clean your barrel thoroughly: A clean barrel is essential for accuracy.
- Improve your shooting technique: Practice proper shooting technique to ensure consistent results.
Preventative Maintenance: Key to Avoiding Ruger AR-556 Problems
Regular preventative maintenance is crucial for minimizing the likelihood of encountering these issues. This includes:
- Regular cleaning: Clean your rifle after every shooting session, paying close attention to the chamber, bolt carrier group, and gas system.
- Proper lubrication: Lubricate your rifle's moving parts with a high-quality gun lubricant.
- Inspection: Regularly inspect your rifle for signs of wear and tear.
- Use quality ammunition: Use ammunition that meets the manufacturer's specifications.
By understanding the potential problems associated with the Ruger AR-556 and following these troubleshooting steps and preventative maintenance guidelines, you can ensure a more reliable and enjoyable shooting experience. Always consult your owner's manual for specific instructions and safety precautions. Remember, if you're unsure about any repair or maintenance procedure, consult a qualified gunsmith.
