Rifle Scopes Where are my NF ATACR Zero Stop experts at?

[Iamero]

I just got two ATACR 7-35 F1s and my first one had zero issue setting at all. I removed the indicator cap, then loosened the 4 clutch screws. You're normally supposed to turn the upper clutch until it makes contact with the lower clutch by rotating clockwise. On my first scope it was no issue at all and I got them contacting, backed it off just a bit, and tightened everything back down...good to go.

On my second one the upper clutch stops rotation a full 360 degree revolution above the lower clutch stop (there is no engagement at all). I didn't want to apply excess pressure to try and get it to turn that extra full rev since the first scope was smooth as butter. Am I missing something here or will this one have to take a trip to Nightforce?

Note: that upper clutch will only turn about 1/4 revolution in either direction before it meets resistance and cannot be turned any further. If I tighten everything back down I can make full revolutions with the turret, but that upper clutch won't move to set my zero stop on this scope.

I see this issue has been posted about a few times on here but people either address the wrong issue or they say they messed with it until they figured it out. No one has reported what they actually had to do to make it work.

When you reached your zero point, was your turret on the 2nd rev?

 

[Iamero]

Uhhhh maybe? What do you mean? From my zero I can turn down 10 Mils until I bottom out the turret.

 

[TangoSierra916]

So when you found your zero sounds like you were partially through the first rev with 10 mils left to bottom. When you dialed down did you have felt clicks?

 

[Iamero]

Yea I gave that a try but all it does it re-engage the center part of the turret and start making audible clicks and actually starts adjusting the reticle again.

I have a similar but slightly different question. I zeroed and zero stopped my scope *same zero stop as OP" when I first got the scope 5 months ago and except for an issue unrelated to current issue, have had no issues.
So, now I am moving the scope to a different rifle and I shot some groups and I am about 1 mil high at 100yds, so I need to dial down, but the zero stop is set so I cannot dial down.
I fiddled with it. I unloosened the scope cap and tried turning things, that didn't do it. I loosened the 4 clutch screws and tried turning things and that didn't do it. With the clutch screws still loose I tighten the turret and tried to turn down, but hit the zero stop.
So, need to figure out how to unset the zero stop so I can zero the rifle and then reset the zero stop.
The manual doesn't cover this aspect. I thought the manual covered first setting the zero stop just fine, but I don't see where it tells you how to unset and then reset after zeroing.
Any assistance appreciated ! Worst case, I'll call NF tomorrow and ask them.

@wigwamitus take the elevation cap off, loosen the clutch screws, and turn it down with a Allen key how ever many clicks you want it up or down.

Pretty sure you can leave the clutch loose while you re-set your zero also.

Ah, down in the GOLDEN HOLE !!! Ok thanks !!!

I have the same exact issue on my new 7-35. I'm calling them tomorrow to see whats going on. I've done everything I can think of besides applying excess pressure and potentially breaking something. My clutch will only rotate approximately 1/4 a rotation in either direction as well. Did you ever find a resolution to this Iamero?

 

[mjsand44]

I have 4 nightforce atcars. I recently purchased a 7-35 and cannot get my zero stop to engage. Every time I try it moves the reticle. I would be interested in hearing how your issue is fixed. My scope will go in for service after hunting season.

 

[Iamero]

I called them on it. Basically the clutch gets stuck on these. Sometimes can be loosened via some turning but otherwise it has to go in to NF for service and they’ll get it freed up.

Damn, thats what I figured. Did you end up having to send yours in?

 

[Iamero]

I’ll be gone for a while so I’m going to send it in after I get back. All the adjustments still work on it and everything, just no zero stop at the moment.

 

[Wangdangler]

I got you. I suppose ill be sending mine in. I really hope the turn around isn't too long. Sucks to have to send it back after waiting a while to get it in the first place.

 

[Iamero]

They said a max of 4 weeks but usually turn those fixes around in 1-2.

 

[Wangdangler]

I really appreciate the info. Ill be calling them tomorrow and sending it back in. Ill update the post with what the say. Thanks again, looks like we might of all been a part of a bad batch.

 

[Wangdangler]

Call NF this morning. They said I needed to send it in. They told me they would expedite it since it was a new optic. I went ahead and shipped it out. $75 for insured shipping later, it’s on the way. Estimated turn around 1-2 weeks with a max of 4. Will follow up once I hear anything else.

Surprised they didn’t provide a shipping label since it’s a new optic. $75 is hard to swallow to ship a new optic back that may have made it through QC with an issue. Unfortunately, this is probably the norm.

Yea, I was not happy about that at all considering I paid $50 for 2 day shipping to get it here approximately a week ago. I asked about them paying for shipping to and from, but they said they will only cover return shipping.

 

[Wangdangler]

Update: Shipped on Monday, got a call today saying it was done and shipping back. Haven’t received tracking yet, but supposedly it should be back here soon. Still a bit butthurt about having to pay $75 to ship and insure a brand new optic back, but at least it was quick. Told me they replaced the zero stop mechanism and checked everything else out.

Good to know. If you’re going to switch it between rifles ever then be very gentle when tightening down the 4 screws on the clutch or chances are you’ll bind it up again and won’t be able to set that zero stop again.

Yea I have a calibrated torque driver that I step up in increments to 4in lbs when tightening them to make sure that doesn’t happen. This one came out of the box that way.

Ok finally got around to trying this. I tried turning "down" the golden set screw ... I turned it down 3 quarter turns and fired a round before and after each quarter turn. I for the first 2 quarter turns, I left the clutch screws loose and then I tighten them for the 3rd and 4th rounds with another quarter turn down. I got a nice tight group 1 mil above my point of aim In other words, turning the golden set screw did not alter POI.
I.E. I still do not know how to reset the zero stop. it seems strange NF would leave this out of the manual !!??
I guess I will call them tomorrow.
