Building an AR-15 can be a rewarding project, allowing for customization and a deeper understanding of the firearm's mechanics. The process involves assembling various components such as the lower receiver, upper receiver, barrel, and more. It's important to have the right tools and some mechanical aptitude or guidance from experienced individuals.
For those interested in building, starting with the lower receiver is recommended as it's like the 'Legos for big kids'. You can purchase a complete upper receiver to simplify the process and ensure reliability.
