PARD NS4E-70 Night Stalker Ak EX Night Vision Black 5.5x70mm Multiple Reticle
The PARD NS4E-70 Night Stalker 4K EX is a digital night vision scope built for hunters and professional shooters who demand serious low-light performance without compromise. This 5.5x70mm optic combines a 4K CMOS sensor with a high-resolution OLED display to deliver crisp, high-contrast imagery in near-total darkness—down to 0.001 lux sensitivity. Whether you're stalking game at night, conducting security work, or pushing the boundaries of what's possible in extreme low-light conditions, the Night Stalker 4K EX gives you the optical clarity and control to take the shot with confidence.
The real innovation here is the balance between raw sensor power and usability. The 4K sensor captures exceptional detail, but the 2560×2560 OLED display is where that data becomes actionable—sharp reticles and bright, clean contrast make target recognition fast and intuitive. The side-focus design feels natural if you've run traditional scopes, and the tactile coating keeps your grip secure even in wet or cold conditions. You get six reticle styles to choose from, color modes (color, black and white, yellow, green), and a ballistic calculator built in—tools that serious night hunters actually use, not just checkbox features.
Recording and connectivity round out the package. The Night Stalker 4K EX captures photos (2448×1836 JPG) and video (1280×1280 MP4) with recoil-activated and automatic recording, plus audio capture and time-stamped footage. WiFi and the PardVision2 app let you review and manage files from your phone. A built-in 21700 lithium battery plus a replaceable 18650 give you up to 14 hours of runtime. The scope is fully sealed (IP67), tough enough for the field (-30 to 55°C operating range), and rated for 6000 joules of recoil. Micro SD cards up to 128GB keep storage simple.
Optional: The IL1 add-on laser rangefinder and IR illuminator extends your detection and illumination reach—critical if you're pushing distances or working in complete darkness where ambient IR alone isn't enough.

Frequently Asked Questions
What is the lowest light level the Night Stalker 4K EX can operate in?
The 4K CMOS sensor is rated for 0.001 lux sensitivity, making it suitable for near-total darkness conditions. This extreme sensitivity allows the scope to function even when there is minimal ambient light, though the optional IL1 infrared illuminator can further extend effective range in complete darkness.
How long does the battery last on a single charge?
The Night Stalker 4K EX delivers up to 14 hours of runtime on its built-in 21700 lithium battery. A replaceable 18650 battery is also included, giving you a spare power source for extended field sessions.
Can I record video and photos with this scope?
Yes. The scope captures photos at 2448×1836 resolution in JPG format and video at 1280×1280 in MP4 format. Recording features include recoil-activated capture, automatic recording, loop recording, time stamps, and audio. Files are stored on a Micro SD card (up to 128GB supported), and you can manage your files remotely via the PardVision2 WiFi app.
Is the Night Stalker 4K EX waterproof and suitable for harsh weather?
The scope is IP67-rated, meaning it is fully sealed against dust and water immersion. It operates reliably in temperatures from -30 to 55°C (-22 to 131°F) and is built to withstand 6000 joules of recoil, making it tough enough for demanding field conditions.
What optional accessories are available?
The IL1 add-on laser rangefinder and IR illuminator is compatible with the Night Stalker 4K EX, extending laser detection capability to 1100 yards and providing infrared illumination out to 380 yards—a critical advantage for professional users and extreme low-light hunting at distance.
