Win one??? Ones that can be sold (pre86 or whatever it is) are surely very expensive. Looked at what’s involved years ago but decided not worth the money. I’m sure the limited ones available for legal sale are triple or quadruple what they were a few decades ago. I believe you just file paperwork and pay $200 tax and wait on approval. Plus you have to be careful about what’s advertised as legal and what is really legal. Lot of folks get in trouble with HK sear guns and issues. I think it was folks buying DIAS based full auto firearms that weren’t really legal. I sure as heck wouldn’t want problems. Full auto is fun to shoot but it gets expensive between ammo and such. Can’t shoot them at some ranges. I think it would be fun to have a 22 since ammo for plinking would be cheap.
