Upper Receiver Parts & Complete Uppers

The Team Room stocks complete uppers and upper receiver parts, including Knight's Armament, to build or upgrade your rifle from the top down. Drop a complete upper on your lower for an easy caliber or barrel-length change, or work piece by piece with barrels, handguards, bolt carrier groups, and charging handles. Quality upper parts are where accuracy and reliability really come from. Whether you are finishing a build or chasing better performance, stop in and we will help you put together an upper that runs.
