How do you idenify a dupe weapon or armor when you already

[Red-Rika]

I must be missing it but no one said how to idenify dupe wepons and armor. I traded a yas 2000h for a yas 7000v it didnt seem to be a bad trade no red ligths start flashing, it had a couple of %s on it and I never been fsod with it equipped. So how can you tell if you already have the item.

Its impossable to make a distinction between a duplicate item and a non-dupe. There are common dupe percentages on certain weapons, but other than that there is no way to tell but to use common sense in trading.
