Disappointing purchase - Burris FastFire II Reflex Red Dot Sight, 4 MOA Reticle, Black, 300233

I was excited to receive this, but after mounting it I’ve found that the reticle is so hard to find to get on target, which is exactly the opposite of why I purchased this optic. I’ve adjusted both screws to their limits on either end and everywhere else in between to no avail as the reticle stays in the upper left hand area of the sight.
