A big part of the increase in “ghost guns” is that New York’s definition of “ghost gun” includes not only the scratch made guns that most people think of as “ghost guns” but also any gun without an easily read serial number. So regular guns with obliterated serial numbers count as “ghost guns” in New York.

Sadly, the most interesting thing I’ve ever witnessed at my local FFL was a lady coming in to pick up a $10,000 custom over under shotgun that got shipped in from one of those old-world heritage custom shops as a gift for her teenage daughter.

Don’t we already have that (for rifles at least) with basically every AR, AR derivative, and any other rifle with separate upper and lower receivers?
