The Alexander Arms .50 Beowulf Hunter Upper, 16 inches, Black (brand part no. UHU50) is a complete drop-in upper assembly chambered in .50 Beowulf, a hard-hitting big-bore AR cartridge from Alexander Arms built for close-range big game and dangerous-game hunting. Alexander Arms pioneered the .50 Beowulf platform, and this Hunter Upper brings that heritage to any mil-spec AR-15 lower in a straightforward bolt-on package. The 16-inch chrome moly barrel wears a 1:20 twist rate matched to Beowulf-weight bullets, a black anodized finish, and a branded Alexander Arms handguard, and it ships complete with a 7-round magazine and a threaded-muzzle thread protector. Built around the standard AR-15 platform, it lets an existing lower quickly become a serious close-range hunting or home-defense rifle.
