What is an AOW?

Although you may see the term a lot when researching Class 3 weapons, AOW is quite a vague term encompassing many items. AOW is an acronym standing for the phrase “Any Other Weapon.” This term was developed by the B.A.T.F. in the NFA (National Firearms Act) to describe any firearm that is not explicitly addressed. Some of the more common weapons considered to be AOW include cane guns and pen guns. However, AOW also includes firearms such as smooth bore pistols and revolvers that fire shotgun shells and have barrels less than 18 inches long. The taxes involved with transferring AOW weapons are also different. Unlike most NFA weapons, which require a $200 transfer fee, AOW weapons cost only $5 to transfer.

If you’re looking to start a class 3 collection, then AOW weapons are a great place to start. Because they are easier and less expensive to obtain, they are a great jumping off point to ease you into owning NFA weapons.
