Alexander Arms UTA50 Tactical Complete Upper - 50 Beowulf, 16" Black Cerakote Aluminum Receiver, M-LOK Handguard for AR-15

The Alexander Arms UTA50 Tactical Complete Upper transforms your AR-15 platform into a powerhouse for close-quarters hunting and defensive applications. Built around the formidable 50 Beowulf cartridge, this 16-inch complete upper pairs serious stopping power with the ergonomic familiarity of the modern sporting rifle you already know how to run. Whether you're after hog, deer, or need a compact, hard-hitting alternative to standard intermediate cartridges, the 50 Beowulf delivers energy in spades without the length penalty of a longer barrel.

The 16-inch barrel strikes a practical balance—short enough to handle in tight cover or from a vehicle, long enough to wring solid velocity from the big, slow-moving bullet that defines the Beowulf cartridge. The upper ships complete, meaning bolt carrier group, charging handle, and firing pin are ready to go; just mate it to your lower receiver and you're in business. The black Cerakote aluminum receiver stands up to field use and won't flash-reflect like bare aluminum, while the M-LOK handguard gives you modern mounting flexibility for lights, lasers, and grips.

This is purpose-built gear for hunters and shooters who want AR ergonomics and modularity married to a cartridge that hits like a truck at practical ranges. If you're running an AR-15 lower and want to explore something heavier and harder-hitting than 5.56, a complete upper like this removes guesswork and gets you on target fast.
