Description
 
This Alexander Arms AR-15 Entry Upper Receiver comes fully assembled and ready to install on any standard small pin lower receiver. Chambered for the awesome 50 Beowulf cartridge, this upper squeezes 50 Caliber firepower into a standard AR-sized envelope, offering shooters an immense step up the power scale compared to a traditional 223 Remington. An excellent choice for close- to medium-range hunting or home defense, the Entry Upper's short 16.5" Barrel keeps it compact and maneuverable in tight spaces, as well as reasonably lightweight. Features include a Forged 7075-T6 Aluminum Flat-Top Receiver for adding optics and/or iron sights, 2-Piece Mid-length Polymer Handguards, a Picatinny Rail Gas Block, complete bolt carrier group, charging handle and one 7-Round Magazine.

Alexander Arms Threaded Tank Brake INCLUDED
Characteristics: Taking its design from artillery brakes, this unit uses two large impingement baffles in an open form construction to achieve probably the best recoil reduction of the .50 Beowulf® brakes at subjectively 40% to 50%. Blast is directed sideways from the two opposite facing ports on each side. The unit is symmetrical in operation and does not provide reduction of muzzle jump. Back-blast to the shooter is negligible, but there is a noticeable blast to either side of the weapon.

This upper comes equipped with a Forward Assist and Brass Deflector Only. For increased reliability, the ejection port has been enlarged in order to give the larger 50 Beowulf cartridge cases room to eject. As modified, this upper does not accommodate or include an ejection port door.

Barrel diameter under the handguard is 0.980", tapering to 0.907" under the gas block, and finally tapers down to 0.775" at the muzzle. The Single Rail Gas Block is proprietary to the barrel's unique 0.907" Outside Diameter.

Due to the 50 Beowulf's recoil, use of a Fixed Stock or Durable Collapsible Stock such as a MagPul UBR or ACE Hammer is recommended.
