I've been shooting a pollington red dot scope for about 8 years. No offense graydawg but I have no idea why yours was so difficult to set up. All you need to do it stand aprox 10 to 15' away from your target. Shoot at the center and manual move the sight to within 2" of dead center. Then use the screw adjustments to get it centered. This is the perfect placement for aprox. 25 yrds.Just practice and aim a little higher for 35 yrd and 45 yrd shots.

your bennifit however I'm in total agreement with.
