If I was a younger guy, I’d be looking to set up a facility to manufacture AR-15s. I think between the date of the POTUS election and the eventual SCOTUS decision, a guy could get pretty rich.
Stag Arms might still be for sale.
Machining tools can be purchased online, as can 80% lower receivers for AR-15s. Do the other 20% of the machining and buy the other components and you’ve got a legal gun with no federal registration. You’re not on the gun grabber master list.
