This is what I have, bolted to the walls in the corner of my bedroom. Holds an AR-15 and two handguns. Probably won't stop an experienced thief, just slow them down, but thwarts the efforts of little, inquisitive hands. Plus, it's all the firepower I will need at five seconds notice. I recommend checking it out. I ordered mine from CostCo, on sale with free shipping and well under MSRP.
