much said about this in comparisons with other brands etc. kind of like a glock, -- with the wide swings in pros and cons (and I'm sure all the reporters are reputable one wonders if extremes are caused by quality control0) wanted to try the new dials so-9x36x56 mp8 floating dot.

On mine the clicks on the big knob are really definitive and smooth.  The side knob is still the mushy feeling knob like on my old 6-24x, I don't care for that one as much.

while less power variables are more popular-- this magnification range is very competitive and a hard one to compete in. 8 to something. not going to include the s&b and uso as but mostly the leo and night force,  (and if you want to go the additional cost of a conquest, the diavari 6x24x56) this is a tuff field.
first 100 rds.
the scope has a definite yellow tint in the glass, the ior web site states that this is special schott glass for gamma radiation--- boy is that something to think about. -- what does it do start to glow to warn the shooter???
the side (they even call it a focus) has a very fast thread pitch, making depth of field on any power higher than 18 almost impossible. -- except seeing bullet holes at 300-400 yds, not a bad thing in all as the image quality from 9x18 is outstanding -- after that it acts like a different scope.
the large power ring is outstanding and out does all of them
the illumination suffers from ior haze but is bright enough to use in the daylight- so this is a big plus for me.
the elevation knob only has something like 50 moa and it was necessary to use 10 moa in the scope reticle to get to 1000 yd. so the scope is being switched over to a gun having a 20 moa base.-- but the knob is large enough to do 20 moa in one turn.
all detents are positive
the mp8 reticle is outstanding, but the 10 moa cross bar has fuzzys as well as some of the lowers, this is a real quality control problem. - will try to show a picture.

sighted in, on 36 power the scope would go out of focus with every shot, also on 24 power, (first two targets) on 12 power shot the group on the far right. (if interested this is the last 5 rds. of a 300 rd string using moly bullets with no cleaning).
also tried to get some close ups of the reticle , the second longer bar on the left side. looks like a piece of frazeled rope.
what do you think?
1-leave on a nuns door step
2-send it back to check out (yet another) cs
3-try to trade it for a leo.


Posted By: Dale Clifford

refusing to give up, after all I got some ruger #1s to shoot accurately, I removed the scope and twisted the power ring back and forth about a 100 times and stood the scope on the front bell, places golf balls on the top and teed-- just kidding -- run the hair dryer up and down the tube until hot to the touch. after cooling the power ring was much smoother and could be turned with the thumb and fore finger. after re-mounting, and site in the scope was still loosing focus at 36 with each shoot, but the focus problem was noticably reduced at the 24 x setting. 50 shots were used to test the repeatability of the elevation, which worked correctly each time.

probably will, currently testing it as is, some interesting things

after first rd. at 36 focus is lost but can still see blurred bullet holes, continuing with 5 shot groups gives expected small group size, but if refocused poi changes.

large elevation knob is great, at 12x first shot 600 yds. hits, 100% , going back and forth between shots to 100 yds.

no lose of elevation correction going from highest power to lowest power, (execpt for expected poi shift due to sfp).

Sounds like you need to get someone else involved.  Not to advertise for Scott Berrish since it is against forum rules.  But I called and told him about my problem with my IOR and he took the reigns and pushed them like crazy to have a new scope to me in a week.  I did not even buy that scope from him either.

another week passes-- called ior , colorado--  apparently ior is having a lot difficulty getting parts and replacement scopes into the country, or manufactured in that country . not likely that a replacement 9x36 will show up for awhile --- traded scope out for a 3x18 illuminated with big knobs -- should be here soon--- no 3x18s ffp available (just asked didn't want one)
at this point cs is great, but not supported by factory in parts or scopes.

From you previous posts I must be missing something. I would not consider four weeks and since they can not find or fix your scope exchanging it great CS.

Also did Scott B. or someone else get involved as Supertool suggested?
Does IOR know about this post?


Posted By: Dale Clifford
Date Posted: August/06/2008 at 12:14

Didn't get anyone involved, just wanted to see what a regular off the street purchase everyday shooter would run into. -- I doubt if ior knows or cares about this post. Just saying that the people in colorado seemed to be doing everything they could, but were hampered by things out of their control .  No mention was made of optics talk, or any other affilications.

I agree, those fixed 4x IORs are amazing.  I have banged my AR wearing the IOR 4x on the ground a couple times pretty hard and put it through a lot and it just works and works.  Those are really a great IOR product.

finally received and mounted, was suprised at the size, just a little larger than a 4.5x14 leo, it will be interesting -- initial observations.
reticle was good, no fuzzys, sharp edges on mils
red illumination does not have red haze as previous iors
lower power has "inner tube effect" similiar to ffp diavaris except its a sfp, will be interesting comparing the 6x erector system with swaros 6x
the scope is almost impossible to mount on a bolt unless you use an extended riser over the back part of the mount, 2 mts in front of the saddle is not acceptable. but--- the scope is a natural for ar type guns 10/15s and with the smaller size and versatility seems almost made for this
observation--- ffp or first focal plane scopes work best in the lower variable ranges when using lower erector values, such as 3x, thus the reticle only grows 3x as fast, these iors are 6x and the reticle grows 6 times as fast---  to me very unnerving.
anyway the 3 Gen iors are set to hit the distributors about the first of sept, with the larger knobs 9x36 and 6x24 along with a bunch of FFPs
next to test the focusing stability and tracking


Posted By: koshkin
Date Posted: August/16/2008 at 21:07
I have an FFP version of that scope sitting on a boltgun (heavy barrel Savage) and it fits me very well.

How do you like the new knobs?

I really like the knobs, one of the main reasons for going with the scope, the numbers go to 24 moa and with the mils in the reticle will easily reach 1k with almost any cartridge/rifle combo. The clicks (detents) are distinct and positive. I believe Near mgf. is making scope bases especially for this scope to get it back far enough on bolts.

I think you'll find this one works better than the 9-36 all around, Dale.  That thing sounded like a real lemon (and not the first 9-36 I've heard of being one).

I also had no problems with the 3-18 mounting on a bolt rifle; I actually could have moved it back a lot farther if needed.  But for those with a "reclined" head position shooting form, LOP too long, etc, or just prefer to have the scope back farther for any reason, EGW makes quality extended bases.


Posted By: Dale Clifford
Date Posted: August/17/2008 at 08:41
most of my shooting is done prone, so the head position with a high cheek riser is a necessity and forward head movement isn't allowable, couldn't get it to work on either a trg or a spr a4,--- if shooting off a bench it would probably work.
another serious difference from the 9x36 is the side focus, which "throws" the adjustment thru a little more than 180 degrees with a turn of the knob allowing for a much "finer" adjustment of the parallax.


Posted By: Jon A
Date Posted: August/17/2008 at 20:19
Oh don't get me wrong, I can certainly see how it might not be the best fit for some people/rifle combos.  I'm just saying that plenty of us have no problem with it on bolt rifles so a general statement it won't work is a bit strong.  I shoot from prone with bipod a lot as well.

rang out the ior--last nite and today-- guess it isn't going to happen for me.
good-the illumination knob has very positive clicks, not mushy like the leos
bad-- all the settings are the same power-- or same brightness (I guess this has a good side- it makes it the same as NXS and it doesn't really matter which one you put it on)
 
the side windage index mark is impossible to read past the scope mts. ie scope mt. blocks visual inspection.
 
erector spring retaining cap is loose and "wiggles" open
 
good- groups were outstanding sub moa with 16" RRA upper 60 vmax and repeatable thru various "serious" rachetings of the elevation knob.
 
bad- scope has serious "panorama" on highest power the outer 1/8 field of view is out of focus and when swung accross the horizon the field of view "bends" reminds me of 4x12 burris compacts from 10 years ago.
also at 3x the field of view has tunnel effect- its focusing on the inside of the scope which disappers around 4-5 power.
and---- while trying to compensate for this by adjusting the quick focus, the rear lens has a flat spot in it (coloration and image degradation) that you can follow around the field of view as you turn the lens.
pretty much speechless


Posted By: Jon A
Date Posted: August/19/2008 at 13:32
Goodness, your luck with IOR is almost as bad as mine.  Of the three I had the only problem you're mentioning they exhibited was the tunnel effect on 3X, though on mine it disappeared at about 3.8X.  Since my $3000 S&B does the same thing I figured I could live with that.

On the "erector spring retaining cap is loose"--do you mean the "Magnum Lock" that the instructions say not to ever touch?  Yeah, if that's loose it needs to go back.

Edit:  Oh, none of mine were illuminated so they obviously wouldn't have those problems. 


Posted By: Dale Clifford
Date Posted: August/19/2008 at 15:14

yes the magnum lock-

the tunnel effect occurs on my Diavaris and S&B also but more so on the ior.
by comparison it doesn't occur on my 6x erector z6.
hardly use low power on this type of scope, but the panorama ain't good. probably allocate it to a 22lr where 8-10 is about right.

@ Dale/Jon A, am I right to say that many of the problems you guys are pointing out with IOR isolated to the 3-18x42 models, and/or the 35mm tubes?
 
I just ordered the illuminated 4-14x50 30mm and am excited, but also a little anxious at the same time due to threads like this.


Posted By: Dale Clifford
Date Posted: August/19/2008 at 15:31
9x36x56 35 mm tube
3x18 2nd or 3rd gen 35 tube
 
big difference mine is  3x18 is sfp while I believe jons and tools are ffp
and while tunnel effects are common on ffp they are not on sfp


Posted By: supertool73
Date Posted: August/19/2008 at 19:31
I had the spf before my ffp and it also had the tunnel affect.  My 6-24x also had the tunnel affect.  I asked Scott Berish about it once and he said it is common on almost all the variable IOR scopes.  Mine goes away I think on 4x or so.  The reticle is almost to small to use at 3x anyway so it does not bug me to much.  I only have a couple hundred rounds through my ffp.  It will be interesting to see how it works over the long hall. 

To bad about your luck Dale.  I think I would be ready to give up on them if I were you.

The only "problem" I had with the 3-18 FFP was it can't stand the recoil of my 300 RUM.  I broke three before saying screw it and buying a S&B.  Other than that, it was a fantastic scope.  I spent over twice as much money to replace it and I'm still not happy.

Before now I had never heard of the Magnum Lock coming loose on any IOR except in cases where the owner didn't read the instructions and decides to mess with it.

No such problems with the 4-14, it held up fine on the same rifle.  My 4-14 was a tad soft around the edges on 4X but not enough to bother me.  At the time I also had a Leupold 4.5-14 VXIII (that it was to replace) and when comparing the two, the FOV of the IOR was so huge--the Leupold may have been sharper at the edges but its FOV was only showing the very center portion of what the IOR showed so I deemed the IOR superior on low power despite that.  And of course when you crank the power up...the glass, the glass...on 14X it made the Leupold look like a BSA.  I was sold. 

Enjoy your scope, it's a good one.  Mine had the old knobs too, now with the big knobs that's one heck of a scope.

It was either this IOR, or save another year or two for a USO SN3 3.2-17. But that would introduce a whole different dynamic once the wife found out what they cost! She was totally okay with the IOR though because I sold 2 scopes to fund it.

repeatability and tracking shouldn't be forgotten here (and possibly the most important), especially when a scope such as this has a large open knob designed for that.
so back to the range with a 100 rds of target .223 handloads, and this time an upper of known performance, (longer barrel, so es and sd won't be a problem).
a nine poi shot grid box test ranging thru 24 moa in the vertical and 8 horizontal of 5 shots each. each poi was somewhat random
drum roll
the tracking and repeatablilty were outstanding.
next -- mike mcdonalds test of total bottoming out and far left windage and left for a couple of days for springs to set and repeat the experiment in a couple of days.
what happens in the turret, to me is the most important, and can over look a lot of other stuff (plastic turrets)


Posted By: koshkin

You do not seem to be having very good luck with IORs, Dale.  Some of the stuff you are talking about I have never seen on an IOR (lens flat spot, for example).  Also, with the panorama at the highest setting, the rolling ball effect that you are describing is pretty normal: you either have a flat field of view when stationary and rolling ball effect when scanning or field of view curvature when stationary and flat image when scanning, but not flat image at all times.  Fuzzy edges though are troubling.

Yes, tracking is of paramount importance.  Of the 5 IORs I've used, every one has been absolutely, positively 100% perfect in that regard.  I didn't mention it because nobody questioned it.   Though I might be a bit worried in your case if the magnum lock is loose.
Quote and can over look a lot of other stuff (plastic turrets)

You lost me here though.  Are you talking about a different brand?  The IOR turrets are certainly not plastic.


Posted By: Dale Clifford
Date Posted: August/21/2008 at 07:27

no this ior has a solid set ups, the statement was in reference to some other brands, if plastic turrets were a not wanted regardless of plus+ in the scopes- it would rule out getting zeiss and swaros

Also, with the panorama at the highest setting, the rolling ball effect that you are describing is pretty normal: you either have a flat field of view when stationary and rolling ball effect when scanning or field of view curvature when stationary and flat image when scanning, but not flat image at all times.
Ilya --- is this in reference to just IOR???

Dale, the rolling ball effect is there for any scope or binocular.  How much of it you see is a design choice.  If I recall correctly, Holger Merlitz wrote a nice article on it a little while back.  I can try to find it.

I mostly notice the rolling ball effect on the lower powers (with all scopes, not IOR specific).  Maybe I'm looking for the wrong thing.

Brencat, I'm in the same spot for now. I really like the IOR and am looking at the USO real strong. Like you said the USO cost is almost a deal killer. But after looking at this thread again I'm feeling better about the IOR even though Dale is having some problems. As much as I would hate to I'd have to send that one back. I look forward to hearing your report on this new addition. Did you by chance look at the Khales multi-zero in the 30mm tube? That's
one of the three I will choose from once I get alittle more feedback on the USO. But right now the IOR appears to be the best fit for need vs cost.

the ball roll isn't very observable in the other scopes in this price range, either leo, swaro, or NF. no doubt due to the decision based on the premise of the article.
which brings up the question, does IOR think this scope is for bird watching??
the ball roll effect is very evident in my wide angle camera lenses say from 24mm down, but they are never used for panning.

For all I know, the highly evident rolling ball effect in your IOR is indeed a QC issue.  I just wanted to point out, that the effect itself is a pretty normal thing and might be the result of a design choice.

Brencat, I'm in the same spot for now. I really like the IOR and am looking at the USO real strong. Like you said the USO cost is almost a deal killer. But after looking at this thread again I'm feeling better about the IOR even though Dale is having some problems. As much as I would hate to I'd have to send that one back. I look forward to hearing your report on this new addition. Did you by chance look at the Khales multi-zero in the 30mm tube? That's
one of the three I will choose from once I get alittle more feedback on the USO. But right now the IOR appears to be the best fit for need vs cost.
 
Didn't look at Kahles at all. And I could be wrong but don't the multi-zeros only go up to 10x? Anyway, they are great hunting optics but I really wanted a tactical scope to pair with my tac rifle (Sako TRG-22). TBH, I was very very close to jumping on the USO group buy through ARF.com back in July, but concluded that I would be settling for an ST-10 which is all I could afford. The IOR has everything I want -- great optics, the new exposed big knobs, a perfect magnification range, and the MP-8 reticle which is terrific.  Can't wait...

after bottoming out and setting for 2-3 days the turrets were returned to zero and a 3x3 grid was shot. this is comparable to a  1 1/2 in 27 shot group, and assuming a few flyers-- each shot was dialed in and although the groups are only 3 shots they were not shot as a group. the hold pt. for each shot was the 0 at the bottom (unfortunately cropped off). the spring set had moved the "grid" 1 inch to right, and about 3/4 in up. While the "trackability" of the scope was good, the calibration is off a bit.  Elevation held well to 4 moa per turret and actual poi, while left windage was about 4.5 moa per 4 moa turret reading, and for right windage 3.5 actual and 4 moa turret. If one uses holdoff in the reticle this would not be much of a problem.

Why are you testing the tracking of this scope after the magnum lock has come loose?  It should have been sent back.

cost and time of postage (ins)-- if sent back -- get to do the whole thing all over again. don't like the odds.

So you're just going to live with a scope that needs service to save on postage?  Why don't you like the odds--if you didn't mess with it and cause it to come loose you shouldn't have anything to worry about.

IORs have fantastically reliable and accurate tracking, it's one of their strong points.  I certainly wouldn't give that up by not sending it in.
