3X Magnifier

So i bought this magnifier a half of a year ago and i bearly used it . Its in peak condition except that the top part of the magnifier  wiggles a tiny bit (it came out of factory like this) so it fixed it by putting electrical tape beetween the base part and the lower part and now its sturdy like how its should be.

I am looking to trade for a eo tech copy or some kind of holographic sight.
