Building an AR-15 can be a rewarding project, allowing for deep customization and personalization of your firearm. Whether you choose to build the upper receiver, lower receiver, or both, the process involves selecting the right parts and tools, and following detailed instructions to assemble the components correctly.
For those new to building AR-15s, it might be more practical to start with purchasing a complete upper receiver and building the lower receiver yourself. This approach provides a balance between customization and ensuring reliability through professionally assembled components.
