The .350 Legend cartridge, designed specifically for AR-15 platforms, offers a compelling blend of power and manageable recoil. However, like any firearm, issues can arise. This guide dives into common problems encountered with .350 Legend AR-15s, providing troubleshooting steps and solutions to help you keep your rifle running smoothly.
Common .350 Legend AR-15 Problems & Solutions
While the .350 Legend is relatively new, several recurring issues have been identified. Let's address them systematically:
1. Feeding Problems: Failure to Feed or Eject
Symptoms: Rounds fail to properly chamber, or spent casings get stuck in the ejection port.
Causes: This is often linked to magazine compatibility. Not all AR-15 magazines are created equal, and some may not reliably feed the slightly larger .350 Legend cartridge. Other potential causes include:
- Magazine wear: Damaged or worn magazines can lead to feeding issues.
- Improper lubrication: Insufficient lubrication can cause friction and jamming.
- Dirty or damaged bolt: A dirty or damaged bolt can hinder smooth cycling.
Solutions:
- Try different magazines: Experiment with various reputable brands known for their reliability with the .350 Legend.
- Clean and lubricate: Thoroughly clean and lubricate your firearm, paying close attention to the bolt carrier group and magazine.
- Inspect the bolt: Check for any damage or wear on the bolt. If necessary, seek professional repair or replacement.
2. Extraction Issues: Stuck Cases
Symptoms: Spent casings fail to extract properly, becoming stuck in the chamber.
Causes: This can stem from several factors including:
- Over-gassed system: Excessive gas pressure can cause the casing to expand and stick.
- Excessive fouling: Buildup of residue can impede proper extraction.
- Weak extractor: A damaged or worn extractor spring can prevent proper extraction.
Solutions:
- Adjust gas system (if adjustable): Reduce the gas pressure if your AR-15 allows for adjustment.
- Clean thoroughly: Remove all fouling from the chamber and bolt.
- Inspect and replace extractor (if necessary): If the extractor is damaged or worn, replacement may be necessary. This should only be done by a qualified gunsmith.
3. Accuracy Issues
Symptoms: Poor grouping and inconsistent shot placement.
Causes:
- Ammunition: The quality and consistency of ammunition can significantly affect accuracy. Using high-quality, consistent ammo is crucial.
- Sight alignment: Ensure your sights or optics are properly zeroed and aligned.
- Barrel harmonics: Some barrels may resonate differently with the .350 Legend, impacting accuracy.
Solutions:
- Use high-quality ammunition: Experiment with different brands and types to determine what performs best in your rifle.
- Proper zeroing: Thoroughly zero your sights or optics at various ranges.
- Consider barrel replacement (if necessary): If accuracy issues persist despite other efforts, a different barrel may be necessary. This is best handled by a qualified gunsmith.
4. Recoil Management
Symptoms: Excessive felt recoil that impacts follow-up shots.
Causes:
- Lack of proper shooting technique: Incorrect grip, stance, or trigger control can exacerbate felt recoil.
- Heavy barrel: While a heavier barrel generally promotes accuracy, it also contributes to increased recoil.
Solutions:
- Practice proper shooting technique: Focus on consistent grip, stance, and trigger control to reduce recoil impact.
- Consider recoil mitigation devices: A muzzle brake or compensator can help reduce felt recoil.
Maintaining Your .350 Legend AR-15
Regular cleaning and maintenance are vital for optimal performance and longevity. Always consult your firearm's manual for specific instructions. Pay particular attention to the bolt carrier group and chamber, ensuring they are free of debris and properly lubricated.
Remember, if you're experiencing persistent problems, seeking the assistance of a qualified gunsmith is recommended. They can diagnose complex issues and perform necessary repairs safely and effectively. This guide offers troubleshooting advice, but professional assistance is always the safest option for major mechanical problems.
