How about a -real- buyback. Mandatory, say $10,000 per AR-15 [View all]

Make it a carrot and stick.

$10,000 cash, tax free per weapon if you turn it in.
If caught with it, 10 years in jail.

While this would be expensive, this would be a MASSIVE economic boost and solve the gun problem at the same time.

Those kinda of numbers - would get the gunners attention and cooperation (for the most part)
