There are over 400,000,000 guns in private possession. Allow $500 to collect each gun and allow $500 to dispose of each gun. Allowing 5 pounds weight for each gun is 2 billion pounds or 1 million tons. A pile of guns equal to the weight of 9 Gerald Ford Aircraft Carriers. In other words too big to confiscate. Anti gunners need to look for another solution other than confiscation.
