From Guns.com:

Maybe guns aren’t your thing, and that’s OK. Maybe you recently inherited your grandfather’s treasured shogun. While it might have been important to him, maybe it’s not something you’d be interested in using or even keeping around the house. 

If you’re thinking of selling your guns to a government-run so-called “buyback” program, I’ve got one word of advice: Don’t! 

First of all, you won’t be actually selling them. You’ll be turning them in to be destroyed, and that is a difference.
