AR-15 Rifles

.50 Beowulf® | AR-15 Rifles
All .50 Beowulf® rifle assemblies are sold as fully-complete, function-tested, and ready-to-fire products. All available products and options are visible in the Online Store. We do not produce custom weapons.

The .50 Beowulf® was designed to not have an ejection port cover. Clearly, the port is much larger than a typical AR-15, so no, you cannot retrofit one. Trust us, you don't need it. As an addendum, the hinge points are left on the receiver because the upper receiver would cost more to manufacture by removing them from the design. They are not left specifically so that port doors can be retrofitted to the upper and we do not encourage this retrofitting.
Flat-top receiver, 16.5" chrome moly barrel with 1:20 twist and standard Picatinny railed gas block. Direct impingement operating system. Standard-specification lower receiver assembly with our name, logo, and caliber engraved. Ships in an Alexander Arms® soft carry bag with one 7-round magazine. Rifle is standard in black furniture color.
