The Alexander Arms RTA50ST Tactical 50 Beowulf rifle brings the hard-hitting .50 Beowulf cartridge to a familiar AR-pattern platform. Built around a black anodized receiver with a full-length Picatinny rail, it pairs a 16.5" threaded barrel with a slim Alexander Arms M-LOK handguard, EX Performance collapsible stock, and classic A2 grip for confident handling and straightforward controls.

This semi-automatic rifle offers a 7+1 capacity and an optic-ready upper, making it well suited for range work, hunting where large-bore performance is desired, and general training with an AR-style layout. The adjustable stock helps shooters fine-tune fit, while the threaded barrel is ready for compatible muzzle devices. Alexander Arms’ attention to detail and commitment to innovation in the .50 Beowulf platform are evident throughout this compact, purpose-built rifle.
