The Alexander Arms Tactical (brand part no. RTA50ST) is an AR-15-pattern rifle chambered in .50 Beowulf, the big-bore cartridge Alexander Arms created to deliver massive close-range energy from the AR platform. Alexander Arms builds this configuration around a 16.5-inch chrome-moly barrel with a 1:20 twist, threaded at the muzzle with a protector installed, housed in the company’s branded M-LOK handguard over a black anodized receiver with a Picatinny top rail. A collapsible stock and A2 grip keep the controls familiar, and one 7-round magazine ships with the rifle for 7+1 capacity. Among AR rifles, this Tactical model favors hog hunters and big-bore shooters who want .50-caliber thump in a standard AR footprint.
