It really isn't though. Sure I can't go and buy a full auto AR15/AK47 without a special license. However it's pretty easy for me to go buy semi-auto version of that which can also do a lot of damage. There are a few red flag laws like in Texas but they are easily gotten around by private trade, and that's true for most "Red" states. Often no waiting period either if you go to an actual store. It really varies a lot state to state.
