NF ATACR losing clicks?
- Thread starter Covertnoob5
- Start date
Since the dial is translating up and down, I'd wager that the detent is just frozen in place and no longer engaging on the teeth inside.
-13 degrees is pretty rough on grease.

I have seen guys show up at the range with NF and not be able to get their zero after stating they had zeroed at 100 yards and set the stops correctly. First thing I tell them is they should check to make sure they snugged the clutch screws on the zero stop and then I have them check the screws on the turret cap.
I would bet in those temps you have to wipe all the grease off first and then even look at the O rings used.
-25 is pretty extreme, most stuff won't work I am surprised the electronics he showed still did.
When I am in AK teaching everyone asks about temps below -10 down to -25+ and it's pretty tough to give them answers because we never see it here.
Lots of stuff we take for granted doesn't work in those conditions.

I had the 7-35 atacr out in -5 ( wind chill -20) a few weeks ago, fired 25 rounds and did a few tracking tests, so not strenuous testing but all things worked. I’ll wait for another arctic wave to test it more. 😁

We shot our NF NFX’s at last months training in -15 F air temp, -30 to -40 wind chills. Oddly, the elevation turret clicks were mushy/not tactile, felt almost loose. We only shot to 500 but dialing for elevation we were still tracking. Looking back after reading this thread, I’m guessing the detent froze up a bit?
Money unfortunately can't change the fact that grease freezes and will hold the detent in place without engaging on the turret properly. Remove all the grease and you'll accelerate the wear of the turret and make it feel like garbage at all temperatures. You can't exactly replace it with oil either, unless you want it working its way inside the scope itself near the lenses.
I've had my Razor gen2 3-18 and my Viper PST gen1 4-16 SFP out at -12℉ and they worked fine. Power ring and parallax knob were tight but that's expected. Turret clicks weren't as pronounced but they were still there.
My Magnetospeed V3 screen was very sluggish to respond, and did finally stop working after a few hours. I think the screen began to freeze. Once it warmed up it was fine. My phone didn't like the temperature much either and eventually turned off due to the cold.
My Steiner Military 4-16 has been out in extreme cold and worked fine as well. It also had the tight power ring and parallax knob.

Hide, hello!
This is my video 😁.
A few comments:
1. yes, the NF 7-35 really worked perfectly in cold. Exception of clicks, they did not click)).
2. I had NF 3.5-15 and ATACR 5-25 sfp, lupy 2.5-8, 6.5-20, VX5HD 2-10, they all froze equally with NF 7-35.
3. The electronic device is the Garmin 701. The screen freezes and works slowly, but the ballistic calculator counts correctly.
4. Yes, this is a Mosin rifle. It was made in 1927. Barrel replaced by heavy. And it is not small as suggested by AIAW 😊.
5. -26 'C is not so cold for shooting. At -34'C really chilly ).
6. I shot at 460 meters. 3.1 mrad up. In the video, the turrets and parallax are shown already after the shooting, randomly.
7. I am very interested - Tangent Theta will freeze as well as my NF 7-35?

I was hunting coyotes last weekend here in Saskatchewan Canada, was -39*C and Kahles K624i worked perfectly all day long. Got one at 436 yards and K624i never missed a clic. You can hear clics and use zoom without any hassle.

I have hunted, taken game dialing NF ATACR 5-25 in -20-30 here in WY as well as the NF C461 ATACR 552 scopes w/o failure. Late season backcountry Elk weather can get very severe here.
True, knocking off the ice crusted on from firearm/scope in the inevitable 40 degree swings (especially evening) is a pain and either I couldn’t hear / feel the turret elevation clicks - with 20-30 plus mph winds on top of the extreme temps don’t know the answer but I dumped the Elk at range in those miserable conditions and successfully ran back to zero.
I have and had to learn the hard way that certain weapon systems are in my experience certain to fail in those conditions regardless of how careful I ran them (no grease/lubes etc)
This last year I ran the rifle cover (link below) exclusively and it has proved to be quite helpful - but you still need to pay attention your weapon system on a regular basis regardless of conditions.
Each day in the field I build positions that the terrain throws at me - practice fundamentals, dial, dryfire on animals that I have no intention of shooting.
That reinforces my ability to do everything that I need to accomplish during a very short window - but it also keeps me on top of the functionality my gear.

I realize that, I was just ballparking. He listed -34 C in his photo of the Kestrel which is about -30F. Stupid cold in either case. 😉

-20s F has been about the same for all my Nightforce scopes. I can still feel the detents but sometimes it doesn’t click. AMG and GenII were pretty much the same. They all still moved the reticle the right amount.
I always say, I shoot in the cold; I shoot in the wind. I tend to stay home in the cold wind.

Schmidt’s will not allow you to dial out parallax error below about 45-55 degrees for what it’s worth. Was confirmed on a large sample size of scopes so isn’t an isolated issue. You can return them to have them calibrated for colder weather however but I’d imagine you’d lose the ability to dial parallax to 10m
Yup in 45 degree weather we were only able to dial out parallax error to maybe 2-400 yards tops. Beyond that you see the reticle moving. Other scopes we tested in this temperature like the Khales 5-25 and Atacr exhibited the need to dial further (say dial 800 for a 500 yard target) but still had enough travel to eliminate the majority of parallax out to about 1000
