Tunnel effect - Sightmark Ultra Shot 1x34mm 4 Pattern MOA Reticle QD Digital Switch Red Dot Sight

have not even gotten to use it. it seems to be messed up out of the box.it has about 5 rings going on when you look through it giving it a tunnel effect with the dot looking very big I would think because there is more than one of them also. I had just completed a new build to use it on so very disappointed �
