Bear Creek Arsenal (BCA) side-charging uppers have gained popularity among budget-conscious AR-15 builders. However, like any firearm component, they're not without potential issues. This guide delves into common problems reported by BCA side-charging upper owners, offering insights into troubleshooting and preventative measures. We'll explore everything from functionality concerns to potential reliability issues.
Common Problems with BCA Side Charging Uppers
While many users report positive experiences, several recurring issues with BCA side-charging uppers have surfaced online. These include:
1. Bolt Carrier Group (BCG) Issues:
-
Poor Bolt Lockup: Some users have experienced inconsistent or unreliable bolt lockup, leading to malfunctions like failures to feed or extract. This can stem from manufacturing tolerances or improper BCG lubrication. A properly functioning BCG is crucial for reliable cycling.
-
BCG Wear: Over time, even with proper maintenance, the BCG can show wear, especially with high-volume shooting. This can contribute to the issues mentioned above. Regularly inspecting the BCG for damage or excessive wear is important.
-
Compatibility Problems: Using a BCG not specifically designed for a side-charging upper can lead to various problems. Always verify BCG compatibility with your BCA upper receiver.
2. Charging Handle Issues:
-
Charging Handle Failure: Some users have reported failures of the side charging handle itself, including breakage or binding. This can be related to manufacturing defects or excessive force during operation.
-
Charging Handle Stiffness: A stiff charging handle can be difficult to manipulate, especially under stress. This can be caused by issues with the charging handle itself, or possibly friction within the upper receiver.
3. Ejection Problems:
-
Inconsistent Ejection: Side-charging uppers can sometimes exhibit inconsistent brass ejection patterns compared to standard uppers. This is often due to the altered gas system dynamics.
-
Failure to Eject: In some cases, spent casings may fail to eject properly, leading to malfunctions. This can be related to BCG issues, improper gas system tuning, or ammunition problems.
4. Accuracy Concerns:
- Reduced Accuracy: While not universally reported, some users suggest a slight reduction in accuracy compared to standard uppers. This may be related to the altered gas system or other minor manufacturing variations.
Troubleshooting Tips & Preventative Measures
Addressing these problems requires a systematic approach:
1. Thorough Inspection:
- Begin by meticulously inspecting all components – BCG, charging handle, upper receiver – for any visible damage, wear, or debris.
2. Proper Lubrication:
- Ensure all moving parts are properly lubricated with a high-quality gun lubricant. Avoid over-lubrication, which can attract debris.
3. BCG Compatibility:
- Verify that the BCG is compatible with your BCA side-charging upper. Using an incompatible BCG is a common source of problems.
4. Ammunition Selection:
- Experiment with different ammunition brands and types to see if the problem is related to specific ammo characteristics.
5. Cleaning and Maintenance:
- Regularly clean and maintain your firearm. This is crucial for preventing malfunctions and extending the life of your components.
6. Professional Help:
- If you cannot resolve the issue through troubleshooting, seek the assistance of a qualified gunsmith.
Conclusion: Weighing the Pros and Cons
Bear Creek Arsenal side-charging uppers offer an attractive option for AR-15 builders on a budget. However, potential issues like those highlighted above warrant careful consideration. Understanding the potential problems and implementing preventative measures will greatly improve the chances of a positive experience with a BCA side-charging upper. Remember that regular maintenance and proper cleaning are crucial for the reliable operation of any firearm. Always prioritize safety and seek professional help when necessary.
