re: Do I need a permit or anything to buy an AR-15

I think the OP caught the shite he did because he made it obvious that he wanted it because it "looked cool" and was "tactical" after clearly stating he has never owned a gun. I dont think anyone is questioning his right to do anything let alone own an "assault rifle". It just doesnt look good for us (responsible gun owners) when you open the newspaper and read "ASSAULT RIFLE" across the front page because someone with zero experience shot his neighbor while trying to figure out how to strip an AR when never even owning a BB gun. I know that is kinda worst case scenario but the chance of something like that happening is significantly higher when your dealing with someone with no experience that just wanted the gun because it looked cool and he saw it on a video game.
