There seems to be a little confusion with folks here on out of state purchase of long arms.
ANY out of state legal person can purchase ANY legal long arm in ANY state so long as it is transacted through an FFL.
If you are a resident of the state and your state does not prohibit long arm face to face sales then you don't even need an FFL then.
(b) Shall not apply to the transportation or receipt of a rifle or shotgun obtained from a licensed manufacturer, licensed importer, licensed dealer, or licensed collector in a State other than the transferee's State of residence in an over-the-counter transaction at the licensee's premises obtained in conformity with the provisions of 478.96(c).
Yet another innocent act thwarted by instilling fear in the hearts of law-abiding citizens.
