My point was that lower is called An AR pistol. Does that mean the handgun rule applies? Although its a lower I bought and it says Multi. not a designated pistol platform. So under UPS rules does it have to go air next day That was my question.The lower is the only thing legally considered a firearm. You can get uppers shipped straight to your door. But in your example, it would be considered sending a firearm since you are shipping the lower as well.
