Looks pretty good.
I've toyed with the idea of making a cutout in one of the garage walls big enough to conceal a cheaper AR/shotty and handgun with a BOB etc..
Those tactical walls are a great idea, and the mirror and shelving units actually look like nice pieces of furniture too. I will definitely be getting the smaller shelf unit in the next couple months...Although I will say, the staircase stash that was posted on here a while back (though I don't know where) was probably my favorite
