Uppers form the top half of a rifle and house key components such as the barrel, handguard, and bolt carrier group interface. They are used to complete a rifle build, replace worn parts, or change caliber, barrel length, or overall configuration. A complete upper can make upgrades faster and more convenient by combining several major components into one assembly. This category includes uppers built for fit, function, and dependable performance on compatible platforms.
