Common Mistakes to Avoid
When building your AR-15 pistol, you might encounter some pitfalls. Here are a few common mistakes to steer clear of:

-
Ignoring Weight Considerations: While a lighter lower is often desirable, be cautious not to sacrifice durability for weight. Make sure you balance both aspects for optimal performance.
-
Skipping Quality Checks: Always inspect your lower before purchasing. Look for any defects or poor machining that could lead to future problems.
-
Neglecting Proper Assembly: A poorly assembled lower can lead to functional issues. Make sure you follow proper assembly techniques to ensure a flawless build.
Troubleshooting Issues
If you encounter issues with your AR-15 pistol lower, here are some tips to help troubleshoot:
-
Failure to Feed: If your pistol fails to feed, check the magazine compatibility and ensure that the lower is properly aligned with the upper.
-
Trigger Malfunctions: If you experience trigger issues, make sure all parts are properly installed and that you’re using compatible trigger components.
-
Loose Fit: If the fit between your lower and upper is too loose, check the takedown pins and ensure they are seated correctly.
