I have a NFA weapon and would gladly take the hit on the money if it was repealed. S&W 76 was supposed to be named that because that was what it cost to manufacture. Cost me $6700
I saw a show about A10’s on the history or military channel awhile back. One of the pilots they interviewed said that the plane would fly backwards if it had enough ammo and you could hold down the trigger long enough with out melting the barrels.
One more intended or not consequence will be the death of the auto repair industry. As people quit driving the need for repair will go down. Old cars will still need repair but parts availability will become an issue.
