Very frustrating - AIM Sports 1X25 Dual Illuminated Reflex Sight w/ Interchangeable Base

I tried to mount this on a AR-7 Survival rifle and could not get it zeroed vertically for reasons unknown. I mounted it on a 10/22 with a picatinny rail and it was a little better but still at the very end of the vertical travel. The mounting system needs to be re-thought also. Very frustrating to mount. A one piece bar would be much better.
Pros: Good Value for the money
Cons: Very Difficult to set up and Zero
