Found to be a p.o.s. - AIM Sports Inc Dual Illuminated Red Dot Sight

Tried sighting this "optic" on my new Ruger 10/22 rifle back in September, 2015. (By the way I am former military and a a gunsmith), it barely held any kind of "zero" with Match Grade ammo back then. Today I thought I'd give it one more try, before removing it. Using 'match grade' ammo, (.40 grain), with just the the dot, ( . ) setting in both red and green settings @ 41 yds. I was GOLDEN. I then attempted other settings, using the circle, 'plus reticle', plus reticle with the circle, and circle with the center dot. After moving to these other settings ALL WAS LOST!!! I ended up removing the OPTIC and replaced it with a 'standard' .22 scope! Nice idea, (for a cheap price). Save your money and buy an EOTech. You can transfer that to anything from your 'lowly' .22 to your AR platform. (A few spent rounds and they are right back on target!!!)
