Uppers

AR uppers are the upper receiver assemblies used to house key components such as the barrel, handguard, and bolt carrier group interface on compatible AR-platform rifles. 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.
