I was hopping from site to site actually looking for info on IOR scopes and saw your post. I dithered over getting one for some time and decided to go for it. I got a 4-14 X 50 IL with a 30 mil tube, which I fitted yesterday. As of yet I have not fired it, the winds are blowing the trees horizontal at the moment. I did take some photo's
This one is not so good, I have never mastered the technique of taking a photo through the scope, this is 10X magnification.
I got this scope from a dealer second hand, he also had a S&B 3-12 X 56, which I tried side by side with the IOR, and surprise surprise I preferred the IOR. I don't know how that came about as I have S&B's on other guns and expected it to come out on top, but it just never happened that way.
I tried the IL later in the day and it is just the dot in the centre that lights up, enough to put it on the target and not so much as to be confusing and spoil the sight image. It is not the brighest light around but it does the job. The scope seemed to make a more than fair job of gathering light as darkness fell, but this was conducted out of a window from my house and not under field conditions.
So all I can tell you is, it looks OK, the image is clear and crisp right to the edges, it seems to gather the light OK, the illumination is good enough (for me anyway), the magnification ring is smooth to operate, the adjustable eyepiece, ala S&B, is smooth and easy to use, and I like the reticule. Plus I have not found anyone who hates them. I just hope it hold zero OK.
Hope this is of use,
