Hi is it two complete sets of 3 shelves? Or did I read it wrong thanks 

No, it's two sets of wall mount rails and four shelves total. You can use either or both sets of rails and arrange the shelves any way you like on them. More shelves are available a la carte from Global Industrial. They are quite sturdy and will be good for stacking your ammo supply once prices go down again.

Thanks for answering. Let me see where I can use them first thanks. Marlton is where you are?
