So, to Recap
AirforceShooter – Quiet as it’s kept, I live in beautiful, sunny, SoCal; where ordering a really rare steak means that happy cows are stuffed with drugs and fork-lifted to your table. But I digress…
In this state, as in a few others it does not pay to be paranoid; you need the whole set. Still, the best one can do, to be properly accountable to the law, on that level, is to ensure that the sender is following the laws for their state, and the recipient is following the laws for their own respective state.
So, unless you have a high clearance access, or know someone who does – and you are willing to abuse that access – the best you’ll likely be able to do is request verification of the buyer’s age.
The federal government does not give a puppy’s behind, if you send BP arms through their sanctioned mail systems. At least, so long as they’re not loaded, meet the requirements for BP, and yaddacetra, yaddacetra. Mp510 and jimbrto have helped, with some particulars, there.
In a nutshell: On a state level, make sure that you can send the things. Do what you can to reasonably assert the buyer’s eligibility to receive them (verify age and make sure that their state allows for the receipt of your goods). On a federal level, make sure that your items are clean, empty and meet BP requirements. You’ve read what Snaggletooth, mykeal, Macmac and Ed Ames have suggested.
You’ve mentioned that you have given up on sending the items. Hey, with state and federal laws in constant flux, as they are, no one dare call you on making that decision, for yourself. Maintaining your level of comfort means that you are listing to your own intuition. These days, it pays to keep that type of hearing fine-tuned.
Failing that, spend or pass on, the extra costs and send the items through UPS, or FedEx, like bigbadgun, scrat, mp510 and Im283 suggested.
Like the man says: You… Make the Call. And, the best of good luck to you, sir.
