I use the Athlon, sweet scope for the money in my opinion. The zero stop is top notch and the clicks are distinct and right on. I'm out to 750 in the evening light with no problem. The glass isn't 1000 doller glass but the scope price is a steal for what you get I believe. I'd buy another. The gen 1 was crap compared to the gen 2. The customer service is top notch as well.
While I can't speak for their product, I can speak on the Diamondback Tactical FFP. For the price it is extremely tough to beat. If you have any questions on it, don't hesitate to reach out!
