Helpful Tips for Choosing the Right Caliber

1. Identify Your Purpose: Determine what you plan to use your AR-15 for. Different calibers serve various purposes, from home defense to target shooting or hunting.

2. Consider Recoil: If you’re sensitive to recoil, consider calibers like .223 Remington or .300 AAC Blackout, as they tend to have softer shooting characteristics.

3. Budget for Ammo: Different calibers vary in price and availability. Setting a budget can help narrow down your options.

4. Try Before You Buy: If possible, test fire different calibers at a range. This will provide a first-hand experience of their performance and handling.

Common Mistakes to Avoid

• Ignoring Manufacturer Recommendations: Always check your rifle’s manufacturer guidelines for the recommended calibers to avoid damaging your firearm.

• Overlooking the Suppressor Compatibility: If you plan on using a suppressor, ensure that your chosen caliber is compatible with your setup for optimal performance.

• Neglecting Ballistics: Not researching ballistic performance can lead to mismatched expectations, especially if you aim for long-range shooting.

Troubleshooting Common Issues

1. Failure to Feed: This could occur due to a dirty chamber or magazine. Regular cleaning and maintenance should help.

2. Inaccurate Shooting: If your rounds aren't hitting where you're aiming, check your optics alignment, shooting stance, and environmental factors like wind.

3. Stuck Casings: If you find that spent casings are sticking in the chamber, it may be time to clean or replace parts like the extractor.
