What is the purpose of the handguard on a rifle?

The handguard on a rifle serves primarily to protect the shooter's hands from the heat generated by the barrel during sustained fire. This is especially important during extended shooting sessions, as the barrel can become extremely hot and pose a burn risk. The handguard also provides a surface for the shooter to grip, allowing for better control and stability while aiming and firing the weapon. This combination of protection and functionality enhances the overall shooting experience and performance.

While increasing accuracy, enhancing aesthetics, and holding extra ammunition can be considerations in the design of a rifle, they do not pertain specifically to the handguard's primary role. The handguard's main function is clearly oriented towards hand protection and providing a suitable gripping surface for the shooter.
