I received my first ATN 410 scope and was disappointed to observe much less than 5x magnification. I called the company and was told that I could return it. Upon second scope arrival...same thing. I set up a camera and took a picture through the scope, then removed and took picture without...never moved camera or object. I then measured results with calipers. Magnification is only 2.9x. Also, the night vision is extremely lacking (I suppose that Gen1 is just very poor quality). Only good to about 50 yards with infrared light and moonlight. Additionally, one of the scopes had a large fuzzy green spot near the center--right were you try to focus on target--very distracting. Not worth $500 in my mind. Opticsplanet was very good about issuing RMAs and paying return freight.
Cons: 2.9x mag, very heavy, fuzzy in spots.
