The exclusion text reads: " A LICENSED GUN DEALER WHO HAS REMAINING INVENTORY OF ASSAULT WEAPONS ON OR AFTER JULY 1, 2023, AND SELLS OR TRANSFERS THE REMAINING INVENTORY ONLY TO A NON-COLORADO RESIDENT AND THE SALE OR TRANSFER TAKES PLACE OUT-OF-STATE. "
Which means that after July 1 an FFL can sell/transfer an "assault weapon" only to a non-colorado resident out of state. So yes, an FFL and anyone else can still sell their "assault weapons" to anyone else out of state. Not sure how the "non-colorado resident" thing would hold up for someone that is a Colorado resident but they have a second home in another state.
