A lightweight, no-nonsense foundation for your next AR-15 build.
Not every rifle needs extra weight or unnecessary features. Sometimes the best build starts with a simple, well-made upper receiver that delivers proven reliability and Mil-Spec compatibility.
Our Lightweight Black AR-15 Stripped Upper Receiver is precision machined from a 7075-T6 forged aluminum receiver and finished with a durable Type III Hard Coat Black Anodizing for excellent wear and corrosion resistance. Designed with a clean, streamlined profile, this sport-style upper eliminates the forward assist while retaining compatibility with a standard AR-15 dust cover.
Whether you’re building a lightweight range rifle, a practical hunting rifle, or an everyday sporting AR, this receiver provides the dependable foundation you need.

sound of freedom – This was a great set up. I loved being able to customize the set up. Only issue I had was my own fault as a newb to building these. I used a heavy barrel in a slim hand guard. It makes adding attachments tough with clearances. Hoping someday to also get an AR10 from here.
