Well made, holds zero - ATN X-Sight 4K Pro Edition 5-20x70mm Smart HD 30mm Tube Day/Night Rifle Scope

Honesty this optic is everything they claim. Holds zero, 1 shot zero is super easy. Don't recommend using the optical range finder, get the laser range finder add on, it works great. Only problem I've had is occasionally the screen will freeze and I have to long press the power button to force it to turn off then turn it back on. Not a deal breaker, just a little inconvenient. Night vision is really good, I was very impressed. I've owned this optic for close to a year now and other than occasionally freezing, had no issues
