The .350 Legend cartridge, designed for use in AR-15 platforms, offers a compelling blend of performance and versatility. However, like any firearm, it's not without its potential issues. This guide delves into common problems encountered with .350 Legend AR-15s, providing troubleshooting tips and solutions to help ensure smooth and reliable operation.
Common Issues with .350 Legend AR-15s
While generally reliable, several factors can contribute to malfunctions with .350 Legend AR-15s. These often stem from ammunition, the firearm itself, or a combination of both.
1. Feeding Problems:
- Failure to Feed: This is perhaps the most frequently reported issue. It can manifest as the round failing to chamber properly, often jamming at the magazine or feed ramp. This can be caused by:
- Magazine incompatibility: Not all AR-15 magazines are designed for the .350 Legend's slightly larger cartridge dimensions. Using incompatible magazines is a primary culprit. Ensure your magazines are specifically designed for .350 Legend.
- Feed ramp issues: Improperly machined or worn feed ramps can hinder smooth feeding.
- Ammunition inconsistencies: Variations in bullet shape, case length, or crimp can impact feeding reliability. Using high-quality ammunition from reputable manufacturers is crucial.
- Dirty or damaged magazines: Clean and inspect your magazines regularly. Bent or damaged components can impede proper feeding.
2. Extraction and Ejection Problems:
-
Failure to Extract: Spent casings may stick in the chamber, preventing the next round from feeding. Causes include:
- Overly lubricated chamber: Excessive lubricant can cause the casing to stick. Use a light, gun-specific lubricant.
- Improper gas port sizing: Incorrect gas port sizing can lead to insufficient pressure for reliable extraction.
- Excessive fouling: Buildup of carbon and residue can hinder extraction. Regular cleaning is essential.
-
Failure to Eject: Spent casings may not eject completely, leading to malfunctions. This can be due to:
- Weak ejector spring: A weakened ejector spring lacks the force to reliably eject spent casings.
- Obstructions in the ejection port: Dirt, debris, or other obstructions can interfere with ejection.
- Improper gas system tuning: As with extraction, incorrect gas system tuning can affect ejection.
3. Accuracy Issues:
- Inconsistent accuracy: Several factors can affect the accuracy of a .350 Legend AR-15, including:
- Ammunition quality: As previously mentioned, consistent, high-quality ammunition is key.
- Barrel quality: A poorly manufactured or damaged barrel can significantly impact accuracy.
- Sight alignment/zeroing: Proper sight alignment and zeroing are essential for accuracy.
4. Gas System Problems:
- Over-gassing or under-gassing: An improperly tuned gas system can lead to malfunctions. Over-gassing can result in excessive recoil and potential damage, while under-gassing can cause cycling problems.
Troubleshooting Tips and Solutions
- Clean your firearm thoroughly: Regular cleaning is paramount for reliable function.
- Use high-quality ammunition: Invest in reputable brands that are known for consistency.
- Inspect your magazines: Check for damage or wear.
- Check your barrel for obstructions: Ensure nothing is blocking the barrel.
- Consider professional gunsmithing: If you're experiencing persistent problems, consult a qualified gunsmith.
Conclusion
While .350 Legend AR-15s offer a promising combination of power and versatility, understanding potential problems and implementing preventative measures is crucial for reliable performance. By addressing these common issues proactively and utilizing the troubleshooting tips outlined above, you can maximize the enjoyment and effectiveness of your .350 Legend AR-15. Remember, always practice safe gun handling and consult with a qualified professional if needed.
