Looking to build a big bore AR-15? Look no further than the Aero Precision Stripped Upper Receiver – XL. Built from tough 7075-T6 aluminum to Mil-Spec dimensions, this upper receiver is compatible with all standard AR-15 lower receivers and components. But it also features an enlarged ejection port to handle the larger casing of .458 SOCOM, .450 Bushmaster, and .50 Beowulf rounds. Plus, it’s still compatible with standard forward assists and dust covers. And it comes with helpful extras like laser engraved T-marks and M4 feed ramps.
