Not necessarily saying this will cause a firestorm across the nation, striking down gun laws, but how much would a new M4A1, or M-16 go for, or maybe an M60?
On the other side of the aisle, how much would an AR-15 go for, if they’re still produced?
I would expect that they'd cost exactly the same as their semi-auto counterparts, because there's such a vanishingly minimal difference in cost of manufacture.
