Whatever. Don't do anything stupid with it, and no one will ever know you own it. If you don't call attention to yourself, no one will bother checking to see if you own a replica firearm.... Store it in a gun rack, or perhaps a gun case, LOCKED, in a closet or something. Don't take it out and test fire on your deck, using the neighbour's young children as targets... Common sense will keep you from getting busted.
I knew a man once who said "Death smiles at us all. All a man can do is smile back."
