This is too weird for me to understand, so I'd like to know if anyone else has ever ran into this.
Presbyopia marches on, so my wife finally decided it was time for Red Dot on her Buckmark. She'd had great results with the optics on my S&W M22, Neos, and Ruger MkII.
Picked up a Primary Arms MD-FBGII red dot on my way to the range (they are local) for the small size and nice price. Mounted it, and it was dead nuts on at the plate rack.
Finally cooled off enough for my wife to come along with me and she couldn't hit anything with the new red dot, she was ready to have me "just get rid of it!" when I had her try my S&W M22A, she was nailing the plates with it. I tried her Buckmark and found it was still dead nuts on. She was still way off. I then saw she was hitting about 15" low at 10 yards
I adjusted the sight to raise the POI about 14" (not a lot of adjustment left) and she started nailing the plates, I couldn't hit anything with it after the adjustments.
I've introduced a fair amount of shooters to their first red dot experience and once they grok that you need to focus on the target and "look thru the dot" none has ever required any dot adjustments to hit the plates with guns I'd zeroed.
Anyone else ever run into this?
Why only one of four (more counting what is on my SBRs) red dots?
I could understand a left-right shift as possible parallax from the way the brain merges the red dot and the two eyes open image, but don't see a source for vertical parallax. My wife does have a vision defect in that she can not see 3-D effects or do binocular fusion, so she has to close one eye when using binoculars, but she has had no issues using various red dots on my SBRs and other pistols.
