Yes it is legal t is ont classified as a pistol or shotgun it is just classified as a firearm "the Shockwave and remington tac-14 are classified by the ATF as a “firearm” and available to shooters without having to buy a tax stamp or fill out paperwork"range365.com/mossberg-shockwave-gun-test#page-5

You're fortunate to be able to have this in FL. Here in NY our Dictator Governor banned further sales of them.

Jose, yes sir, the Tac-14 is legal in FL, it is not considered a shotgun, because it has no stock, so it can't be a SBS, it is just a 'firearm' and legal in most states.
Stay safe & have a great day!

Hi Jose and welcome. Yes Sir it is FL legal to purchase and own. It is classified as a firearm and will transfer just like any standard handgun. Cheers and happy holidays to you and yours!
