Now I see the poster before me came up with the name but I will add this anyway. I couldn't remember the name and went home and looked at my 5 gun box. The name is Gun Ho and there is discussion about them at:

I bought mine about 8 years ago but have never really used it that much. I have not yet gotten the spotting scope or the mount for one reason and the second reason was it was pretty heavy when you put 5 guns in it with mags. Don't even think about adding the ammo to the box.
The more popular (I think) model would have been the smaller, thinner box, but since I always think bigger is better, I got the 5 gun. It is heavy.
