I took the EVO out today with the See All Sight. I was shooting off sandbags today and the 1st thing I did was sight it in. There are 75 minutes in both up and down adjustment as well as 75 minutes of both left and right, there are no clicks to the adjustment. There's a learning curve to using this thing, it's like a red dot on a handgun searching for the red dot in the sight. Its not as pronounced on a rifle so this took very little time. My sight is the Delta or triangle sight, there are 2 lines that intersect the top point of the Delta which naturally draws your eyes to the delta. Remember keep both eyes open, once acquired you can close one eye to take a fine bead with the top Delta point. I was surprised of how precise I could get it. I was shooting at a public range and sighted in at 20 yds so I had to wait for a cease fire to move the target out further. In the mean time I saw a small rock at the 100 yd berm and basically sighted it in at 100 yds. I did change the paper target to 50 yrds and fine tuned the sight in there. There seemed to be enough friction on the sight adjustments to keep them locked in, time will tell. Overall I am impressed with the sight, ease of operation the only problem I had is the sight is very short and I had to really get down on the sight. I see a riser in my future with this setup. Every time I go out with the Scorpion I am blown away with the accuracy of this gun. I will keep it zeroed at 50 yds I figure most shots will be a lot closer than 50 yds but I would not hesitate to take it out to 100 yds if needed. So this is my 2 cents worth, if your looking for an inexpensive sight I would not hesitate to get this sight.
