Actually, you can arm the ground vehicles (provided you have completed the appropriate paperwork and requirements for a class III weapon or weapons) if you're putting a .50 on top or back in the turret. You are not allowed to arm the airplane without special dispensation from the Feds.
Cooool...*big grin*
Thanks for the info...
I know there are cannon in private hands...and they still compete with them...
Was pretty sure about the aircraft restictions...
Didnt know about arming surplus vehicles(although I should have guessed such) ...I suppose that requires an FFL?
