I was suprised that EBay is allowing the sale of any magazine that holds over 10 rounds. I was trying to sell a rifle scope and included a picture of it on the rifle and they threatened to ban me about three years ago. I deleted the picture and added a couple of just the scope and they left me alone.

Funny or not EBay used to let you buy and sell guns on their site but that ended right after the Columbine shooting in Colorado. I actually bought and sold guns on Ebay when it was allowed.
