When shipping firearms I NEVER use the mention of firearms in the address. If it is going to XYZ Gun Shop I put XYZ GS on the company line and in the name box, who ever it it for. Even if it is ABC Sporting Goods I just put ABC SG. In other words I only use initials for any shooting or shooting related address, if it is a Pawn & Guns I just use Pawn.
Never had a problem and till it gets local the minions inbetween don't handle a package that screams "STEAL ME".
