Someone posted this to the Brotherhood of Red page, and I thought it deserved to be shared here. I can't say that I personally have this much space for gear storage (or the ability to drill into my walls to mount this), but if you can dedicate the space, this is about as organized as you can get.
The individual rack pieces can be found at Lowe's for about $16, or you could get creative and make your own.
I did a quick search for "weapon storage" in the search box, but didn't really come up with crap. So, any of you guys have other ingenious ways you store your gear safely?
