AR-15 Uppers

.50 Beowulf® | AR-15 Uppers
All .50 Beowulf® upper receiver assemblies are fully-complete, function-tested, and ready to fire. 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. 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.


All uppers and rifles are built to order and have an estimated lead time of 4-6 weeks.
