Spikes 37mm flare launcher to DD
I've been reading about adapters to load 12ga rounds into my new 37mm flare launcher and that it will change the classification to a destructive device. I certainly have no intent on breaking the law so before I purchase an adapter I'd like to get the launcher registered correctly. I'm new to the NFA game and I've just started the suppressor paperwork a few months ago. What is the process for registering a destructive device?
Love my guns
