The X-Sight 4K has a 3.5-inch eye relief, and can be moun­ted using 30 mm mounting rings. ATN has provided two standard rings and one L shape ring (For X-Sight 4K Pro only). The L shape ring is for those instances when you need extra eye relief for certain rifles. First, choose your preference of rings and position and mount the bottom portions of your rings to your rail for optimal eye relief. Place the scope on the bottom half of the rings you just mounted, verifying you have sufficient eye relief for your platform. Place the top portion of your ring over the mounted bottom portion, make sure the holes align and the screws turn easily. Apply equal torque to all screws with the provided Allen wrench. Make sure your rings are tight on your rifles rail and will not come loose due to recoil.


For mounting the X-Sight 4K on the Picatinny rail:

  1. Loosen the fixing screws on the sides of the mounting rings.
  2. Place the rifle scope on the Picatinny rail so that the projection of the rail, which is in the base of the ring, enters the recess in the rail.
  3. Tighten the fixing screws of the mounting rings.

Be sure your weapon is not loaded. Use safe weapon handling procedures at all times.

Please do not over tighten the Fixing Screws when attaching the rings to your rail, we recommend using 30 in-lbs.

Rings are only included with the X-Sight 4K Pro models only.

ATN IR850 Infra-Red Illuminator

The IR850 IR Illuminator is only included with the ATN X-Sight 4K Pro models. If you have the Buckhunter model skip this section.



Please hold the battery tube (not the flashlight head or neck) when Tightening/loosening the tail-cap.

The IR850 IR Illuminator uses two CR123A batteries.

  1. Remove the tail cap unscrewing it until it is free of the body.
  2. Install the battery in the body, observing proper battery polarity.
  3. Install the tail cap back on the body.



The IR850 has three stage output — Low, Medium and High system. Low at 5%, 20 h. Medium at 30%, 8 h. High at 100%, 1.6 h.

General Mode:
The factory preset modes control the brightness of the IR850 illuminator.
The three modes are designated on the tail cap that activates the modes. The modes are distinguishable by the size of the dot on the tail cap. The small dot indicates the lowest power output setting. The medium dot indicates the medium output power setting. The large dot indicates the strongest output power setting.
To activate the desired mode, turn the end of the tail cap, so that the dot indicator is aligned with the desired power output. This will turn on the required output for your needs.
To turn off the IR850 illuminator, simply turn the tail cap so that the dot indicator is positioned on the off setting.


Turn the light on maximum output and shine it on a wall 8~10 m away. To focus the beam, hold the head in one hand and turn the neck section with your other hand turn clockwise or counter-clockwise.


Attach the IR850 to adjustable mount as follows:

  1. Unscrew the two screws.
  2. Place the insert in the mount.
  3. Insert the illuminator into the mount with in­sert.
  4. Secure the two screws using an Allen wrench. Do not apply excessive torque.



In order to Align the IR850 illuminator to your scope. After the IR850 is assembled into the mount. Place it on the X-Sight side accessory rail or on your rifles accessory picatinny rail. Once mounted securely, slightly loosen the two screws on top of the mounting ring.
While looking through the X-sight at night with night mode activated. Move the IR850 around in the mount until you see the IR light covering your entire field of view in the X-sight view finder. Once you have adjusted your IR light to be aligned with your X-Sight FOV, gently tighten the two screws on top of the mounting ring with an Allen wrench.


To prevent wear and retain water-resistance it is a good idea to lubricate the threads and o-rings if they become dry.

RAV (Recoil Activated Video) is a fantastic feature that allows you to set your scope to record your video when you fire your weapon. But as there are many types of calibers and platforms our standard RAV sensitivity may not be enough. IE small calibers that have little recoil, which fails to activate RAV. With this option you are able to adjust the sensitivity of your scope in order for it to recognize the light recoil and activate RAV.

For best results you should only Calibrate RAV at a shooting range. ATN endorses safe and responsible recreational shooting, and does not recommend RAV calibration at home regardless of state law.


Open the Shortcut Carousel and navigate to Settings. Scroll to Profile/Zero and then select RAV calibration. You should see a velocity rating in the upper left corner ( __ . __ ft/s or m/s ) followed by “1, 2, 3”. The First circle is blinking denoting actively searching for input. While having the RAV calibration active fire a round down range. You should see example (9.4 ft/s) or something similar, as it will depend on the caliber and your platform. Once you get the first number press the center OK button center to save. Repeat this process with only your desired input until there is a check mark on all numbers. If an error has been encountered either with ammunition, loading, or any other possible malfunction, simply press the left button to leave RAV calibration. Afterwards, please repeat the process. Once this has been accomplished your scopes RAV is calibrated to your caliber, grain, velocity, and platforms felt recoil.
By following this process, you should be able to use RAV with the ammunition and platform used during the calibration process.


We have conducted tests to 22 Air rifle and 22 Long Rifle successfully increasing the sensitivity of RAV.


Before Zeroing your scope, please make sure the correct lens type is selected. You can check this by going to the System Settings and selecting Settings. You will see the subcategory Device Type. Please make sure you select the lens type of your scope.
This lets the system know which Scope you are actually using (example: X-Sight 4K 3-14 or 5-20).

To Zero in your scope you will need to go to the Profile/Zero section of the System Settings, or select it from the Shortcut Carousel.


To enter the System Settings, open Shortcut Carousel with OK button center and select the wrench icon with RIGHT or LEFT buttons right-left . Or select the Zero Reticle shortcut from the Shortcut Carousel.
Push the OK button center to enter the menu.

Before you begin the Zeroing process you will need to either create a new Profile or utilize an existing one. We recommend to create a new one to understand the process better.


Under the Profiles/Zero Category you will find Current, Other, Import from SD card, Export to SD card. Select Other. There you will see Profile 1 and Create New Profile. You can select Profile 1 and edit it, or create a new one and make changes to it. Once you select a profile, press the OK button center to load it. Once the profile is loaded, it becomes your current profile.
Profiles are primarily used in order to utilize your scope on various weapons. This way, when moving your scope from one gun to the next, you can simply select the Profile that you have already created for the particular gun you are using. Multiple profiles are also used to zero in the scope, on the same gun, but at different ranges. For example, one Profile may be called AR 50 yards and another AR 200 yards. Allowing you to create two separate profiles to better fine tune your shooting solutions for both shorter and longer range shooting.
In order to change the profile name to what you want, open the ATN Obsidian app and connect your Phone/Tablet to your scope.

To zero your rifle with the ATN device, follow the next few steps.
Zeroing Scope:

In the System Settings, Select the Profiles/Zero Tab. The main Subcategories of the Profiles/Zero are Current, Other, Import from SD card and Export to SD card. Select Current, by pressing the OK center button. There you will see Zero Reticle. We suggest you fill out all the ballistic info, to the best of your ability, before proceeding to Zero. This will save you time when you want to use the Ballistic Calculator at a later time.




Proceed to Zero the Reticle. Press the OK button center to select Zero Reticle. You will see on your screen a cross hair reticle. While keeping the gun as steady as possible, fire a round. Use the key pad and scroll wheel to move the Red cross hair to the point of impact. While keeping the White crosshair in the same place you where aiming. Once you have placed the Red crosshair on the POI, press the OK button center. A dialogue box will appear with options. Select Save & Exit.

Although you may not need more then one shot to Zero in your scope, we do recommend that you repeat the process several times to make sure that you truly are Zeroed in. As you gain experience in Zeroing in your scope it should take you no time at all to Zero it.



In order to fine tune your zero, select the Zero Reticle once more. Press the OK button center and select Zoom. Zoom in all the way and fire the weapon. If your POI is not where you aimed, move the Red reticle to the POI and Exit & Save. This will ensure your POI is the same on optical and maximum magnification.


Using the Smart Range Finder will allow you to estimate the distance to your target, as long as you have reasonable knowledge of the size of your target.

To have this feature enabled you must activate Advance Mode settings.

Once the distance is measured, the value will be automatically integrated into your Ballistic Calculator.

Select the Flag Icon from the Shortcut Carousel.


Pressing the OK button center will take you to the Main Screen of the Rangefinder feature.


To measure the distance, follow the next steps:

  • put the arrow-mark on the top of the target and press the OK button center , wait for the scope to take the readings (it will take a number of readings so try to keep your weapon steady);
  • put the arrow-mark under the target and press the OK button center;
  • if satisfied with the value that was generated, press the Function button to go back to the Homescreen or repeat steps 1 and 2, if necessary.


During the measurement process, you can zoom in and out using the Scroll Wheel.

If the Target Height is incorrect you can change it:

  • press the RIGHT button right to enter the Menu;
  • сhoose one of the presets or input the height manually;
  • accept the height with OK button center and go back to the Main Screen.


Allows you to input or correct the distance manually. Choose the Distance Entry option to launch this function.


Change distance value using the Scroll Wheel or Keypad buttons up-down. To accept the new distance, press the OK button center.


Ballistic Calculator

The X-Sight 4K has a fully integrated Ballistics Calculator that enables your scope to seamlessly adjust its point of impact. The first step in utilizing this function requires you to enter all relevant information into the Profile that is being used.


To have this feature enabled you must activate Advance Mode settings.

If you do not know all or part of this info (example: Initial Velocity), we recommend that you contact the manufacturer of the ammunition and/or the weapon that you are using. Generally this info should be found on the manufacturer’s website.

Once your profile has been setup, you are ready to activate the Ballistic Calculator on your sight. Open the Shortcut Carousel and follow the instructions in this section.
You will need to use your key pad and Scroll Wheel or Keypad buttons up-down, to find the Ballistic Calculator bullseye icon.


If this function is off (indicated by a diagonal line running through the icon), you will need to turn it on by pressing the OK button center while having the icon selected. You will see the diagonal line disappear and the Ballistic Calculator icon will appear in the top right corner of the screen.


Profiles which are not in use are situated in the Other section. You can use an existing profile or create up to 6 new user profiles.



To edit a Profile, select it (highlighted in red) and press the OK button center.
Choose the action you want to perform; Load, Copy (Duplicate) or Delete the selected profile.



To have this feature enabled you must activate advance mode settings.


There are a number of Environmental elements that may be entered to increase the precision of your shots.


Wind strengths and direction are by far the most important of the group, especially during medium to heavy winds. We highly recommend that if you plan to shoot at ranges over 300 yards. Take wind readings and enter the information into your sight. Both wind speed and wind direction are needed if you plan to make accurate shots. You can enter the information through the Environment shortcut or your mobile device using the Obsidian App with a WiFi connection to your scope, whichever you find easier.

Humidity must also be entered through the Environment shortcut or by utilizing the Obsidian App.

Barometer Pressure, Altitude and Temperature:
Pressure, Altitude and Temperature will be set automatically using your sight’s internal sensors.

Other Data Collected:
The angle of your scope, as in relation to your target, is also noted and the Ballistic Calculator takes the information into its calculations.


Clearly, the number one priority to achieve accuracy in long range shooting is to know the range to your target.
The Ballistic Calculator will make your adjustments for you, but only after you have entered the distance to your target.
Your sight offers several ways to accomplish this task.
