The National Association of Gun Rights is stating that the second round can come as soon as August 27th. The UN will attempt to establish gun controls on us through a "Programme" as opposed to a Treaty and then have Obama through Executive Orders force this issue upon the American citizen.
The official title of the "Programme"; United Nations Programme of Action to Prevent, Combat, and eradicate the Illicit Trade in Small Arms and Light Weaponse in All It's Aspects.
Part of this program is to restrict the sale of firearms, require registration of all firearms, and restrict the sale of ammunition.
Buy a gun, buy lots of ammunition, learn to safely use the weapon, become a marksman in the use of that weapon and stand ready when called.
