I feel like this would be the right place to ask this question...

So, I feel like I've earned some well deserved time off. I'm going to fly to see my brother and parents in NH. While I'm there I thought I'd go pop a few caps in some paper (they live on a set of land where I can do so legally and safely). SO, does anyone have a good guide to flying with an AR-15? I've flown with my Glock and my Kimber on multiple occasions but I haven't flown with a rifle before.

I know it has to be unloaded in a locked hard case.... ammo separate... anything else I'm missing?
