ebay question

I've been selling items on eBay for about a month now and haven't had any issues until today. one of my items was removed, the item was a old G3 rifle by Dragon. the email i got from ebay said that it violated its policy on replica firearms and gave a list of things you aren't allowed to do but none of them seem to apply to a small 1/6 scale rifle. i doubt it need a orange ended barrel and i'm pretty sure it cant be converted to fire actual bullets.

i was wondering if any of you that may buy and sell have ever encountered anything like this and if there is any negative repercussions.

thanks for any help you can provide.
