The Fort Eustis (VA) AAFES PX counter is just now open, but minimally stocked so far. They have at least one dedicated, knowledgeable salesperson, not just someone off the floor. In addition to the main exchange's firearms, ammo and accessories, there are two other tactical gear sources in the building - Military Clothing Sales and a private concessionaire out in the main passageway.
It is too bad that NEXCOM doesn't go with a concessionaire if they don't want to do it themselves.
