Common Issues During Assembly and How to Troubleshoot Them

When it comes to assembling an AR-15 with a lower parts kit, it's not uncommon to encounter a few hiccups along the way. But fear not! We're here to help you troubleshoot common issues and ensure a successful assembly.

One common issue is difficulty installing the roll pins. These pins can be tricky to insert, especially if you don't have the right tools or technique. To troubleshoot this, make sure you have a roll pin punch that matches the size of the pin.
