A word to the wise make sure you paper work is up to date at all times. You will get checked sooner or later.
In maryland in the Baltimore area we have lost 5-8 Dealers to stupid mistakes on paper work of one kind or another . Some dealer had been in the bussness for 29 yrs or more. they got laxed in the paper work and ATFE shut them down. Also most people don't know that went you sell your own guns and have an FFL it must go through the books. When I go mine the ATFE came and made sure I had a comercial adress , that is part of our zoning laws in the county I live in. Also we have a pistol License , you would be checked for that too.Only one name goes on that license here, in the case of a partnership. Maryland is very hard on Gun Ownership.
