18" 50 BEOWULF Bull Barrel AR15 Upper Assembly with 15" Rail and Thread Protector

The .50 Beowulf is a 12mm caliber rifle cartridge developed by Bill Alexander of Alexander Arms for use in an AR-15 rifle.  The cartridge utilizes a rebated rim, sized to match the rim of the 6.5 Grendel round. The case body is very similar in dimensions to the .500 S&W Magnum Revolver cartridge, being slightly longer and fully tapered for automatic feeding in the weapon. The round is intended to improve stopping power greatly at short- to medium-range as compared to the standard 556 NATO  round.

    I ordered this this upper and a upper from Bear Creak Arsenal. I was un able to fire this upper due to no ammo, so i will say this upper and the Bear Creak felt much different. This upper seemed better quality. This is of cores just my opinion.
