Are flash bangs legal in the U.S. for civilians (Missouri)?

My husband, who is not the prepper in the family, asked last night if I knew if flash bangs were legal for civilians to purchase. I looked online but most of what I found didn’t look reliable or was sketchy looking. I don’t think we will ever need flash bangs but, as a general rule, I try to encourage any questions or interest that he shows. If he’s interested in something new then I’m all for it. A few flash bangs won’t hurt anything if it will keep him thinking along the lines of preparedness or SHTF.

If they are legal to purchase, does anyone have a recommended place to buy from?
