They are not planning on banning any of those guns. Keep them. Plus, when they say ban, they do not mean confiscation. They just want to make it where you cannot buy, or transfer certain guns.
The main guns they are trying to ban are so called "assault weapons" (an incorrect term since none of these guns are select fire). They include guns like the AR-15, civilian version of the AK-47, and possibly the FAL and Ruger Mini 14 and 30.
Once you own these guns, they are yours. If they ever do try to actually confiscate them, be prepared to live through a Civil War.
