Maine’s private gun sales are built on trust, but in 2026, trust should always be backed by a signed Maine Firearm Bill of Sale. This document is your shield in the Pine Tree State, recording the buyer’s residency and the firearm’s unique serial number. It provides a permanent record that the transfer was a legal, person-to-person transaction. Should any questions arise regarding the firearm’s history, you will have a dated, signed contract to prove exactly when and to whom the weapon was sold.

Maine Firearm Transfer FAQ
Is a background check required for private sales in Maine?
As of 2024/2025, Maine law requires background checks for private sales that are publicly advertised (e.g., online or in newspapers). For sales between unadvertised private parties, it is recommended but not mandatory.
What is the 72-hour waiting period in Maine?
Maine has implemented a mandatory 72-hour waiting period for most firearm purchases. This means 72 hours must pass between the agreement to sell (Bill of Sale) and the physical transfer of the weapon.
Are there exceptions to the waiting period?
Yes, transfers between 'family members' (as defined by statute) and certain other specific cases may be exempt, but for most private sales, the 72-hour rule applies.
What ID is required in Maine?
A valid Maine Driver's License or State ID is required. You must verify that the buyer is a Maine resident and at least 21 years old for handguns (18 for long guns).
Is a Bill of Sale mandatory in Maine?
While not strictly mandatory, the recent changes in Maine law make documentation critical. A Bill of Sale proves when the 72-hour waiting period began and that you verified the buyer's ID.
Who is prohibited from owning a gun in Maine?
Felons, those adjudicated as 'mentally ill,' and individuals subject to an Extreme Risk Protection Order (Red Flag law) which was recently updated in Maine.
Can I sell to someone from New Hampshire?
No. Private transfers across state lines are illegal under federal law. You must use an FFL dealer for any sale to a non-resident.
Does Maine have a gun registry?
No. Maine does not have a state-level gun registry. Your Bill of Sale is your private proof of transfer.
