What to watch for
- Important: Maine: advertising a private firearm sale itself triggers a background-check requirement.
- Caution: Interstate transfers must ship to a licensed dealer (FFL) in the buyer's state for the background check; a private buyer can't take a handgun across state lines.
- Note: Maine has a waiting period (about 3 days, though the law has been challenged in court — verify it is in effect) before a firearm can be received.
- Note: Never transfer to a prohibited person or complete a straw purchase (buying for someone else) — both are federal crimes.

Yes. Maine requires private firearm transfers to go through a licensed dealer (FFL), who runs the background check.
Do you need a permit or license to buy a firearm in Maine?
This summary doesn't list a state permit or license requirement to buy a firearm in Maine. A dealer sale still requires the federal background check, and local rules can add requirements — verify current law.
Does Maine restrict "assault weapons"?
Maine does not have a state "assault weapons" ban, though federal rules still apply.
Are magazine-capacity limits in effect in Maine?
Maine does not impose a state large-capacity magazine limit.
Is there a waiting period to receive a firearm in Maine?
Yes — about 3 days, though the law has been challenged in court — verify it is in effect. The federal background check must also clear before transfer.
