Wayne, yes Sir. It initially was not when first released but has since been deemed Ohio Legal. Ohio law now mirrors Federal law on the definition of a sawed-off shotgun. The Mossberg Shockwave, Remington Tac-14 and future similarly styled guns will now be legal in Ohio. Cheers and you and yours stay safe!

Wayne, yes sir, 100% legal in Ohio.
