Yes, the Aero Precision AR15 XL Stripped Upper Receiver is compatible with AR15 pattern Port Doors/Dust Covers.
The dust cover will fit, and will work for a while, but in my experience the larger plastic 'tail' for the spring will catch the bolt sooner or later and break. It is meant to rest against the bottom lip of the ejection port, but that has been removed for the enlarged port. I have broken a couple this way.
