The Alexander Arms UTA50 Tactical Complete Upper 50 Beowulf 16" Black Cerakote Aluminum Receiver M-LOK Handguard for AR-15 is built around a robust .50 Beowulf chambering and a 16" threaded barrel, giving AR-15 shooters a hard-hitting upper that is ready to drop onto a compatible lower. The black Cerakote aluminum receiver pairs with a free-floating M-LOK handguard to provide durability, corrosion resistance, and ample mounting space for accessories, while the included thread protector keeps the muzzle safe when no device is installed.

This complete upper arrives function-tested and ready to run, making it a straightforward choice for shooters who want to add .50 Beowulf capability to their existing AR-15. With its optic-ready configuration, carbine-length gas system, and 7-round magazine compatibility, it is well suited for range use, hunting, and general training where heavy-hitting performance is desired. The thoughtful design and execution reflect Alexander Arms’ reputation for innovation in specialty AR-15 calibers and purpose-built uppers.
