AR lowers are the lower receiver assemblies or components used as the foundation for compatible AR-platform rifle builds. They house key fire control and magazine-related parts while helping determine fit, function, and overall configuration during builds, repairs, and upgrades. Different AR lower options can affect compatibility, controls, material, and setup style depending on the project. This category includes AR lowers built for proper fit, dependable function, and practical everyday performance.
