They are commonly used in new builds, caliber changes, barrel length changes, repairs, and overall rifle upgrades. Different AR upper configurations can affect handling, compatibility, weight, and intended use depending on the setup. This category includes AR uppers built for proper fit, dependable function, and practical everyday performance.
