Alexander Arms Upper Receiver Build Kit AR-15 Pistol 50 Beowulf 12″ Barrel 49/64″-20 Thread Black
Product Overview
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, 12″ threaded barrel, complete bolt carrier group with bolt, thread protector, and of course one 7-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 12″ 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.
