I had exchanged a previous purchase for this one because of the longer eye relief the Mustang has. Extremely satisfied with the result and the eye relief is right on as listed in the specs. Out of the box at 25 yards the shots were around 3 to 4 inches high and slightly right. The adjustments were quick and easy and within 30 minutes my shots were dead center. Reset at 50 yards and shots were slightly high as they should have been with the new distance. A few more minor adjustments and all shots back in the red and dead center!! It is staying true each time I go out. Great looking scope as well. The only negative is that it is a heavy scope and added more weight to my AR than I would have liked. But the comfort in shooting has offset that and you can't beat the price for this quality optic. Customer service at Vector Optics is also A+++.
