Leapers op3 1.5-6x36 crossbow scope, - UTG Pro OP3 1.5-6x36mm Crossbow Scope

I purchased this this week because I have had great success with another Leapers UTG scope on my Air rifle.
Also I review the reviews and looked at many other Crossbow scopes. I love the level bubble for align the vertical straite up and down. I used it with a plumbers bob hanging out at 20 yards I noticed the level in scope at base has lines for centering it worked perfectly. I love the side focus and wind-age and elevation control settings. I mounted in on my Barnett 360 DropTine Crossbow. First I set the wheel at 360 fps and site in at 10 yards. Then Moved the target 20 yard and shot the first bolt right under the foam block. I was nearly 6" low at that point. I could not get enough elevation up adj untill I reset the speed to 350. Wow I shot one bolt or so high then made down adjustment and shot the next one in one " bulleyes base one inch low. then up elevation say 9 clicks+- shot two more bolts both in the bulleye .5 " high. on second shot I had to look twice to see were it hit. These were Swackers It at first looked to be one hole and one flyer but it was two holes and four blade slices. I noted the second arrow had red paper in to it. So I took a re-look see and found the shaft hole were nearly .3 inch center to center. Nice clear bright site picture. the range marks are perfectly advisable.
