Remington says to "Contact any Remington Authorized FFL gun dealer who buys from a Remington LE wholesaler".
Not all wholesalers are Remington LE wholesalers, but you should be able to find a local FFL dealer who has a contact with one.
It's not that Remington doesn't sell or want to sell LE guns to "civilians", it's just that not all dealers buy from Remington Wholesalers, or that all Remington Wholesalers are LE wholesalers.
