Rifle for Home Defense?

I would guess that most gun owners, including me, have a handgun (or two) in the home for self defense.  In my case, these guns are loaded and in quick access safes to prevent an unauthorized person from getting to them.  If I need a rifle or shotgun, those are unloaded in my safe in the garage and will take significantly more time to get.  Ever since the slaughter of 26 people in a Sutherland Springs, TX church, I've been considering how to have a rifle in my house ready for quick access.  In case you don't remember that case, Stephen Willeford engaged a heavily armed and armored shooter with his AR and was able to stop the rampage.  Rifles are used for self-defense fairly frequently.  Over the summer, I wrote about a man fighting off five home intruders with an AK47.  Recently, I just saw this article about a pregnant women who saved her husband and his daughter from home invaders with an AR15.  

Right now, I'm considering three different options.  Two wall mount options: Gunvault or Hornady.  The third option is  a Hornady under the bed safe.  I like the idea of hiding a wall mount safe in my closet behind my hanging clothes.  Let me know if you have a rifle ready for quick access and what your preferred method of securing it is.
