Aluminum tape = 0.005 "

I used 0.040" of aluminum tape shim towards the back of scope

Alternate screws front and back a little at a time to allow them to be in alignment

Hand tight only, do not get too manly with it, aluminum body - will strip easily

this will fix your reticle falling to the bottom of screen when adjust for zero

if you have 20 MOA rail you won't have to shim

ATN /Scott/Sachal - if you're reading this please incorporate a tilt in your mount going forward

Did you shim between the scope and mounts? Or did you shim between the scope and it's mounting base/bracket?

Scott Country has sent an initial email of the testing to ATN...

What did the email say?

I have no idea. I responded back saying I hoped the testing results were positive. They responded back that things looked good. They just were waiting on ATN to answer some questions.

between the scope and scope base / bracket

I shimmed between the bottom of the scope mount, and the rail on my rifle, but heh, what do I know. I wonder if it would make any difference on the amount of shim required if I did it the other way. Oh well, too bad, I am not going to take it apart when it is working well enough to pop raccoons at 125 yds.

Yes it does make a difference on how much you shim, thats the reason I used and suggest feeler gauges. You get the option to use one piece instead of using multiple pieces of whatever. Every weapon is different as are the scopes and they need different thickness of shims to make it right. You can use tape but its not my way of doing it, I like a solid shim to work with.

Shadow. Interesting. I agree on using something "solid", hence the square of coke can. However, I can visualize it needing "less" shim if done higher up, b/n the scope and its mount. I will try that if or when I do take it apart, just for grins. So if you use feeler gauges, do you use a boresighter?, or do you just modify between rounds? Also, where do you buy tiny scraps of metal with these kinds of tolerances? Thanks, Tom

I use a boresighter and sight adjust with the shims at 25 yds . I then move to 100 yds and zero with the scope with live rounds. Then come back to 25 and make the final adjustments with the shim and the boresighter. The thing I like besides the solid foundation is the fact that the holes in the feeler gauges just happen to fit perfect on the screw threads. Once you get the right shim in place just cut it (on the hole side) to about 1/2" and remount.
Windage as you will notice if you do this will constantly change, I usually mark the base to the scope for as close as I can get, from there I usually fold a soda can piece over on it self and mount up that way.
As these scope are not true to the weapon you need to get it as close to possible to the bore. That leaves very little adjustment and therefore keeps the reticle on screen. This holds true to a long range scope as well but very seldom anymore do you have to shim, mostly just hone the mounts if using cheap ones. Maybe ATN could have learned that lesson but I think the quality control just wasnt up to snuff.
After the update comes out you wont have to take the shims out as you have gotten the scope close to true to the bore, just leave it be unless you want to play or change weapons and then you get the honors of going through the whole process again...

Here's the setup for my Blaser R93 rifle:

ATN X-Sight 3-12X, Contessa QD mount and a short T50 in 940nm.

The mount is great,back bolt is adjustable right-left and the
picatinny rail is detachable, so a 1mm washer was inserted
between the rail and the mount, shimming is easy

For those who aren't shimming but are following the thread , you may be wondering if the shim is being used for right to left adjustment (windage) or up and down (elevation).

To be honest I'm sorta confused myself so those of you discussing the shimming can you relate which you are correcting when stating your method?

Thanks

Sorry if I was unclear, havn't tested yet, but what I ment is,
with this mount, it's possible if needed.
Both, up-down and left-right.

/MKL

The comment was for everyone in general MKL not just you, with the washer in place on you blaser mount - the purpose is to move the crosshairs UP, correct?

Thanks

the shim was for Up/Down adjustment

Got the 3x yesterday, just mounting it to the rifle atm, was
i ment was, with the current firmware dropping reticle, i want
to get my scope to be as accurate to zero as possible without
zeroning in the scope, hopefully its fixed the new software but
then i dont have to move my reticle much.

/MKL

Sorry but I thought I made it clear as to what I do for the windage. By far not the best but for me the easiest.


On the ar platforms if I need to take the xhairs left i will shim the right rear, if I need to go right I will shim the right front. Hope that makes it clearer.

I just checked Scott country's Facebook page and one of their "field testers" claims the shifting reticle issue has been corrected with the .234 firmware.
Nothing else reported about other features that ATN might have added for them to test.
He tested the scope on a .223 rifle.
No firmware update on the ATN website.
I was hoping we'd have the update available by this weekend, so I could do my own testing on some critters.

Maybe someone will have to start a .234 thread soon ?

THIS!

I am that "field tester", and can confirm that the reticle is fixed. At the moment, however the reticle will be off centre if that's where you zeroed it at until you start zooming. When you zoom in, the reticle moves to the centre and once centred will stay there until you zoom back out. As I understand it, ATN might tweak the zoom to get the reticle centred at all times.
As far as other features, the beta I tested specifically dealt with the reticle. Many other functions were actually disabled such as video recording etc, as it was truly a beta and not a final release. As far as I can tell there aren't any other features to test in that beta, but that's not to say they won't be part of a final release. The other fixes may well be unseen ones.
if your scope is badly misaligned you will still want to adjust it to get it as centred as possible, however if you're only a little off, the update will be fine.
My crosshairs are dead central and a touch high so I had no issue with the slight movement of the reticle when I was zooming in.
I did also test POI at different magnifications as have other testers and there is absolutely no change in POI across the mag range.
As for when the final version will be released, I have no idea. The test findings have gone back to ATN so I'm waiting with everyone else for a fully functioning release!

thanks for the update.

Thanks for giving us a first hand report on your field tests.
Lets hope that your test results will lead to a better scope in the future.

Jimmy,

Thanks for the update, Just a bit of clarification.

You say the reticle stays centered until you zoom back out. Does that mean if the reticle is not centered at 1x, when you go to 1.5x it is centered until you get to full zoom, but when you go back out to 1x it is not centered again?
