The Alexander Arms AR-15 Upper Receiver Build Kit is the perfect kit for anyone wanting to create a one-of-a-kind AR-15. The Upper Receiver Built Kit comes with key components such as a complete upper receiver, charging handle, gas block, dowel pins, gas tube, 16.5″ threaded barrel, thread protector, complete bolt carrier group with bolt, and of course one seven round magazine. Chambered in 50 Beowulf, this upper receiver kit squeezes 50 caliber firepower into a standard AR-sized envelope, offering shooters an immense step up in power compared to a traditional 223 Remington. This Upper Receiver Kit is an excellent choice for a do-it-yourselfer who enjoys custom work and mix-and-matching components to find out what works for them. The upper receiver kit works great for close-to medium-range hunting or home defense with its 16.5″ barrel for tight spaces, and reasonably light weight construction. The upper receiver assembly features a forged 7075-T6 aluminum flat-top receiver matte black finish.
