I just recently bought a T5xi from Europtic that was labeled "small blemish" I really can't say what the blemish was, maybe the finish under the anodizing was a little rough I don't know what else it could be, but it definitely was mounted and possibly used for a bit(slight bit of corrosion on the screw on the bottom of the turret when I took it out of the box) . . I mounted it on my 6.5CM and proceeded to sight it in. I was having trouble focusing and the parallax knob seemed to be off some. Then yesterday I finally got to shoot past 200 yards. The parallax knob/focus is labeled in meters, so it should "around" the same for yards. I could not get a consistent focus until I turned it down past 75 meters on the knob, and at that it was still slightly blurry. I couldn't get it right and it made me eyes fatigued and gave me a headache. I bought this thing because I thought they got the bugs worked out on them. It does have the updated turret (logo), and I trusted Europtics. I've bought more than a few scopes from them over the years. I'm just speculating, but it seems who ever had it before me probably came to the same conclusions as me and returned the scope.Has anyone else had this problem? Is it fixable? Any feedback is appreciated.
