I got the Nikko scope on Tuesday, but did not have a chance to review it untill this morning.. First impression was positive.. The Nikko scope was well packaged. It was completly wrapped in a gold cloth which is the same type of material that most manufactures send for cleaning scope lensed but this was almost like a small towel..

Then it was in plastic wrap as well..
Anyway I chose my S1K .20 caliber to mount it on.. I shoot this one quiet often and it would stack pellets and clover leafs all day long..

If I am haveing a good day... hehe..
The mount was ok and very basic. It only has three mounting bolts which were the same size as the Accushot mounts... The screw that mount the scope to the base of the mount are very small.. I was not impressed.. But as long as it holds thats good.. I am used to the Accurshot and BKL mounst which have larger hardware. The scope has the same arrangment as the Leapers Scope with the lens covers.. That was the second thing I did not care for. When I am out hunting, those lens cap covers go in my pockets and they can be very uncomfortable when sittting etc. for me...

These lens covers were a lemon encondesant plastic.. I think it makes the scope look cheap... And I totally prefer screw on lens covers..

Easy to carry.
Ok so after I mounted the scope I set up at 40 yards to see how far I was off. Was hoping for only a couple clicks and would be on target, but that was not the case.. The scope I had on the S1K .20 was a BSA 4-12-40AO and it was on the money.. Anyway after about 20 clicks down and 5 or so clicks to the right it was right on the money.. I sat there and put 15 pellets in and touching the bulls, most of which were single holes.. Could see about 5 holes from where I was at. Thes Nikko Stirling 4-12X42AO Gold Crown Air Rifle Scope is a nice scope.. It rates better than the BSA 4-12X40AO I had on the S1K.. The turrets are easy to turn ,1/4 clicks. They are definetly very nice and not loose at all, but not so tight that you cannot turn them while sighting in on your target..

The AO has rubber ribs around it which makes it easy to adjust in the field.. The power adjustment also has rubber ribs for easy grip.. One thing that the Nikko Sterling has and I do not see any advantage is the eye piece moves in and out for plus and minus fine tuning.. My eyes are not that fined tuned any more to take advantage of this feature.. hehe. The Nikko Sterling is a bit on the heavy side but not over 15oz. I never did see any specs on the weight.
All and all I think the Nikko Sterling is a good air gun scope. I would not buy another one though..

But of course this is my own opinion.. . My problem is that I own a couple Simmons ProAir scopes which in my opinion have sharper and clearer lenses plus they are lighter in weight..

Below are some pictures of the Nikko Sterling Scope mounte on my S1K .20 and also some pics of one of my Simmons ProAir Airguns scopes mounted on one of my S1K .177's..
