[QUOTE="Pdvdh, post: 250027, member: 4191"] Sounds like a developing consensus is that the IOR's track very well and have great glass. There was a definite breakage problem with their FFP 3-18 scopes. Their SFP 3-18 scopes seem to have a decent track record. IOR is now on their 3rd generation of 3-18 FFP scopes and so far there aren't any failures to report that I know about. Scott with Liberty Optics (a site sponsor) would be the source to tap for the most current information on the 3rd generation 3-18X. I happen to own two IOR 3-18 SFPs, so I'm glad to hear that tracking shouldn't be a problem. I can add that I recently ran an elevation turret test on one of my 3-18 Xs. I cranked the elevation 70 clicks in up and 70 clicks down. I obtained the same total travel in both directions. The scope returned to zero. My elevation turret averaged 0.249" per click, based on the total of 140 clicks of measured travel during my test. So I was pretty happy with those results. I can also add that as far as resolution goes, I just don't see how it could get much better than what I can see through my two 3-18 IORs. I can believe that there are scopes that transmit more light, but the clarity with which I see through my IORs is pretty impressive. And I have some Swarovski binoculars and optics, as well as a Zeiss spotter to compare them to. [/QUOTE]
