Things I liked:1/4 click adjuster knobs.
Sharp Focus came in play after setting up the scope.
There was no instruction on setup. But with a little thought the process was easly done. First mounted. then set front ring on Say 30ft. Set a target at 30ft. Loosen the eye ring and rotate as many times as it takes to get the focus sharp at 30ft. Lock the ring. then the focus at distance works pretty nice. then I bore sited it and targeted in in close then at 24 yards and at 30 yards. Easy to track Tree rats running thru the branches. Things I would have changed:Small instructions on how to get the focus working at a measured distance and range finder at the same time. My scope was the fuzzy image at first. It would focas with the range finder ring but the range was all wrong.
1.Secure the scope on your rifle.
2.Set range finder on a marked distance.
3.Measure distance and place target there.
4.Loosen rear optical and ajust to sharpest image then tighten the rear optical.
Now your ready to site it in. What others should know:Using this on my 33 year old Webley-Scott Vulcan 177.
The spring in this is a shortened Winchester 1000sb.
I inserted the spring into Webley-Scott Vulcan and cut it off aproximately 1.75" longer the spring chamber. It cocks now at 37.5 LBS and holds its own in power and tight groups.
The Turks spring is king of springs. I have left this one cocked over night and several hours daily. It never took a set or lost any power.
I found this to be the scope used on the new Winchester 1028 I had owned a Model 1000SB it was a scope killer. It took a solid block mount to stop the mount and scope from moving. Then it killed the last scope was a Centerpoint milldot tactical scope was fund for less than 12 shots. The windage Adjustment quit working. I had replaced that scope with a 4-12 Power Bushell scope with front range focus that held up very well now it is on my 22mag rimfire rifle and I think I will keep it there.
Things I liked:The Weight The balance The feeling I got a good arm work out while enjoy ever shot I make with it. The combination of Accuracy and Insane power this spring gun. My Hatsan 135 is 22 cal. It is a supper high pellet gun possible the highest of all brake barrels is amazing to say the least. Squirrels on branches are launched into the air with direct hits. Things I would have changed:A warning that over use might give you great arms. What others should know:Use great caution shooting this gun. The power of it can stop a person if hit with in 150 yards dead in its tracks. Do not let your child play on his own with it. This is a true mans gun.
