The dealer has to comply so that limits what guns can be transferred via FFL.I never really understood one thing about running personal transfers through an FFL - maybe that means I don't sell enough guns to have had to worry about it - but does the FFL have to worry about the transferred gun being compliant with whatever bullshit lists or conditions FFLs have to comply with in MA or do they just pass it through? It hits their books, right? I could swear I've had some dealers transfer anything and others balk at some stuff.
