The AR-15 platform is known for its modularity, and the upper receiver is a key component in customizing and building your ideal rifle. The Guntec USA AR-15 Billet Upper Receiver promises a solid foundation for any AR-15 build, focusing on quality billet construction at an accessible price point. Manufactured by Guntec USA in Scottsdale, Arizona, this upper receiver boasts a flat top with a 1913 Picatinny rail, M4 feed ramps, and compatibility with mil-spec components.
