Any Other Weapon
Any Other Weapon’ is the catch all used in the National Firearms Act. This category was designed to catch anything that was not a rifle, shotgun, handgun, or one of the NFA regulated categories.
Instead of the $200 tax due with most Form 4s, the transfer of an Any Other Weapon only requires a $5 tax. This makes the purchase of an AOW quite inexpensive compared to other NFA firearms.
