Sightmark Wraith 4K 4-32×40 Review: Day/Night Scope Tested

My Savage Axis II in .308 wears the Sightmark Wraith 4K 4-32×40. I’ve used it for six months on predator calls, hog control, and nighttime property defense. One scope handles dawn deer stands, midday varmint shooting, and after-dark coyote work.

The Wraith handles multiple hunting scenarios, but spending $75 more on the ATN X-Sight 4K Pro gets you triple the battery runtime and a ballistic calculator that matters.

How I tested the Sightmark Wraith 4K 4-32×40

I mounted the Wraith 4K on my Ruger American Ranch chambered in .308 Winchester using a one-piece 20 MOA Picatinny mount. This rifle gave me a consistent platform to evaluate the scope’s performance under real hunting recoil and field conditions.

Initial Setup and Zeroing

Setup took about 15 minutes once I figured out the menu system. Honestly, I fumbled around more than I’d like to admit before finding the brightness controls. The included quick-start guide helped, but I ended up downloading the full manual to my phone.

I zeroed at 100 yards using Federal .308 Winchester 150-grain soft points. The digital reticle adjustment worked smoothly, and I had it dialed in within 12 rounds. I saved this zero profile in the scope’s memory, then created two additional profiles for different loads.

Daytime Performance Testing

I spent multiple range sessions evaluating daytime image quality at different magnifications. Shot paper targets from 50 to 300 yards, testing how well I could identify bullet holes and make precise shots.

The 4K sensor performed well up to about 20x magnification. Beyond that, digital grain became noticeable. Not unusable, just not as crisp.

I compared the Wraith’s daytime image to a traditional Vortex Diamondback 4-12×40 scope I had on hand. The digital display held up surprisingly well in good lighting conditions. The glass optic still had a slight edge in color accuracy, but the gap was smaller than I expected.

Night Vision and IR Testing

Night testing happened on my friend’s property where we deal with persistent coyote and hog problems. I conducted sessions in various moon phases to see how the scope performed with different ambient light levels.

With the IR illuminator on high, I could positively identify coyote-sized targets out to 285 yards. Hogs were visible to about 300 yards due to their larger size. The 850nm IR provided better range but created a faint red glow visible to anyone looking directly at the scope.

I took shots on coyotes from 75 to 240 yards and hogs from 100 to 275 yards. The scope held zero perfectly after each shot. Image washout from recoil lasted less than a second before the display stabilized.

Battery Life Evaluation

I tracked battery life across six hunting sessions using fresh Energizer CR123A batteries. Runtime averaged 4 hours and 10 minutes in preview mode with the IR set to medium. Recording video dropped that to about 3 hours and 40 minutes.

Cold weather testing at 18 degrees Fahrenheit reduced runtime to roughly 3 hours. That’s when I started keeping spare batteries in my jacket pocket instead of my pack.

Swapping batteries with gloves on took about 45 seconds. Not ideal when you’ve got eyes on a coyote, but manageable.

Durability and Weather Testing

The scope spent time in my truck bed, got rained on during two hunts, and experienced temperature swings from 18 to 95 degrees. The IP55 rating held up to light rain and morning dew. I didn’t submerge it, but splashing from a water crossing didn’t cause issues.

After 400+ rounds of .308 Winchester, the scope showed no signs of electronic failure, loose components, or zero shift. I bumped it against my truck tailgate once by accident and winced, but everything kept working.

Recording and WiFi Features

I recorded over 50 video clips during hunts and range sessions. The 4K footage quality was good enough to review shot placement and identify mistakes. Audio recording picked up the rifle report and my commentary.

File sizes averaged 400-500 MB for a 5-minute clip. The WiFi streaming to my phone worked within about 30 feet. Beyond that, connection became spotty. The app let me change settings and review footage without removing the scope from the rifle.

Sightmark Wraith 4K 4-32×40 Data Range Analysis Test Results

Testing conducted with Federal .308 Winchester 150gr soft point ammunition on bolt-action platform. Night testing performed in rural setting with minimal ambient light.

Generation Type & Image Clarity

The 4K CMOS sensor delivers some of the sharpest digital images I’ve seen in this price range. Daytime clarity rivals good glass optics at lower magnifications. Colors stay true, which matters when you’re trying to distinguish a fox from a rock at 200 yards.

The 1280×720 display might not sound impressive on paper. But it’s plenty sharp when you’re behind the gun. I’ve glassed fields at dawn and watched targets come into focus with excellent detail.

The digital nature means no chromatic aberration or edge distortion you’d get with cheap glass. That’s a nice bonus.

Magnification & FOV

The 4-32x range gives you serious versatility. I typically keep it around 8x for scanning, then dial up to 20x when I’ve located something worth investigating.

Beyond 20x, you start seeing digital grain. Still usable for confirming your target, just not as pretty.

Field of view shrinks fast as you zoom in. At 4x, you get a decent viewing area for tracking movement. Push it to 32x and you’re looking through a soda straw. I rarely go past 24x unless I’m stationary and have time to really study what’s out there.

Performance & Detection Range

The IR illuminator reaches out to about 285 yards on a coyote-sized target in my testing. That’s with fresh batteries and the IR set to high. I’ve spotted hogs at 300 yards, but positive identification was tough without better ambient light.

Daytime performance extends much further. I’ve clearly identified targets at 450 yards with good lighting. The digital sensor handles midday sun better than I expected, though you’ll want to adjust brightness settings as conditions change.

Worth noting: the ATN X-Sight 4K Pro pushes detection range a bit further at 350+ yards. Something to consider if you’re hunting open country.

Eye Relief & Eye Box

Eye relief stays consistent at around 3 inches regardless of magnification. Makes sense for a digital scope. You don’t get the scope shadow you’d see with traditional optics.

I run it on a bolt gun, and cheek weld positioning is critical for getting the full display picture. The eye box is forgiving enough for quick shots. I’ve come up on targets fast and found the sight picture immediately.

It’s not as quick as a red dot, but it beats fumbling with eye relief on a traditional scope.

Durability and Recoil Resistance

This thing weighs over two pounds. That heft translates to solid construction. The aluminum housing has taken bumps in the truck and light rain without issues. IP55 rating isn’t fully waterproof, but it handles field conditions just fine.

I’ve fired over 400 rounds of .308 through my rifle with this mounted. Zero holds tight. The electronic components haven’t hiccupped once, and the display shows no dead pixels or glitches.

It handles recoil better than some cheaper digital scopes I’ve tested that lost zero after 50 rounds.

Battery Life

Two CR123A batteries give you about 4 hours of runtime. Maybe a bit more if you’re not recording video. I carry spares because running out of juice mid-hunt is not an option.

The batteries are easy to swap, but you lose your sight picture while doing it. Cold weather drains them faster. I tested it at 18 degrees, and runtime dropped to about 3 hours.

Keep spare batteries in an inside pocket so they stay warm. This is the scope’s biggest weakness for all-day hunts. The ATN X-Sight 4K Pro’s 18-hour battery life makes this look pretty rough by comparison.

Day/Night Usability

Switching between day and night modes takes two seconds through the menu. The transition is smooth, and you don’t lose your zero.

I’ve used it during that tricky twilight period when there’s not enough light for traditional scopes but too much for full night vision mode. That’s where this scope really earns its keep.

Daytime operation is where this scope surprises people. The 4K sensor produces images that compete with quality glass. Night mode with the IR illuminator turns darkness into usable hunting time.

The green reticle works best for me in night mode. Red tends to wash out against certain backgrounds. Having nine color options means you can adjust for whatever you’re hunting over.

Recording and Streaming

The built-in recording captures 4K video with audio. Great for reviewing shots or just documenting hunts. I’ve recorded dozens of sessions, and the footage quality is solid enough to share.

The scope stores files on a microSD card. Controls are straightforward once you learn the button sequence. I can start recording without taking my eye off the target.

The audio picks up your shot and any conversation, which adds context when you review later. File sizes are reasonable. I’ve fit multiple hunts on a 64GB card.

Additional Features & Capabilities

The 10 reticle patterns include standard crosshairs, German posts, and ranging options. I stick with a simple duplex most of the time. Being able to switch colors on the fly helps in different light conditions and backgrounds.

The scope remembers your settings between uses, including your zero. I have three profiles saved for different loads.

The menu system takes some getting used to. After a few range sessions, it becomes second nature. Digital zoom flexibility means you can fine-tune magnification instead of being locked into fixed power settings.

Accessories

The factory mount works, but upgrading to a quality quick-detach setup makes more sense for serious use.

• Sightmark Wraith Quick Detach Long Mount: Rock-solid QD capability that returns to zero and makes swapping between rifles quick and easy.
• LUMENSHOOTER A8S 850nm IR Illuminator: Extends your night detection range beyond 150 yards with zoomable beam focus, and includes everything you need—battery, charger, pressure switch, and scope mount.
• Sightmark Quick Detach Battery Pack: Solves the battery life issue completely, giving you all-day runtime for extended hunts.

Summary

The Wraith 4K delivers legitimate dual-purpose capability that works for both day and night hunting. I’ve used it in conditions ranging from bright afternoon sun to pitch-black predator hunts. It performs admirably in both.

The 4K sensor produces images sharp enough to rival traditional optics during daylight hours. Night vision mode with the IR illuminator opens up hunting opportunities after dark.

Battery life remains the scope’s main limitation. Carrying spares is mandatory for serious hunting trips. The weight might bother some shooters, but it contributes to the scope’s durability and recoil resistance.

For hunters who want one optic that handles day and night work without breaking the bank on dedicated night vision, this scope hits the mark. The recording capability adds value beyond just shooting. It’s not perfect, but it delivers where it counts.

How the Sightmark Wraith 4K 4-32×40 Compares Against Others

The Sightmark Wraith 4K 4-32×40 delivers solid 4K imaging at an entry-level price. Short battery life and weight are real issues, but it gives you day/night capability with good zoom range. For hunters getting into digital night vision, it’s a reasonable starting point.

The ATN X-Sight 4K Pro 3-14x adds serious value for $75 more. The ballistic calculator, rangefinder option, and 18-hour battery solve the Wraith’s biggest weaknesses. Rechargeable batteries save money long-term. It’s the smarter pick for regular hunting use.

The Night Owl Optics NightShot is the true budget option at $299. Fixed 3x magnification and no video recording limit its versatility. But it’s lightweight at 20 ounces and runs on cheap AA batteries you can buy anywhere. Detection range maxes out around 75 yards. For rimfire pest control or getting your feet wet with night vision, it’s dirt cheap.

The Pard NV008SP2 LRF is the premium choice at $799. At only 17.5 ounces, it’s incredibly lightweight compared to the others. The built-in 1000-meter laser rangefinder and ballistic calculator make long-range shots easier. IP67 waterproofing means you can hunt in serious weather.

To Summarize

I’d get the Sightmark Wraith 4K 4-32×40 if you’re testing digital night vision and want 4K recording with serious zoom range. The battery life frustrates me, but carrying spare CR123As solves that. You get solid day and night performance at a mid-range price.

The ballistic calculator and optional rangefinder help you make ethical shots instead of guessing. For $75 more than the Wraith, you’re getting features that matter every single hunt. The Obsidian 4 processor handles transitions between day and night better than the Sightmark’s electronics.

The Pard NV008SP2 LRF is worth the extra money if you need a built-in rangefinder and want to save serious weight. At 17.5 ounces with a 1000-meter LRF already installed, it’s the lightest premium option here. But the shorter zoom range limits long-range identification compared to the Wraith’s 32x.

For most hunters doing predator or hog work, get the ATN X-Sight 4K Pro. Better value, longer battery, more magnification, and a huge user community for troubleshooting.

Why should you trust me

I’m Richard Douglas, a firearms instructor and tactical advisor who runs Scopes Field. I’ve worked as a National Defense Security Consultant and spent years teaching marksmanship and optics use. My advice has been featured in major firearm publications, and I’ve consulted for manufacturers like Bushnell, Leupold, and Sightmark.

I’ve wasted thousands of dollars on scopes over the years. That experience taught me which features actually matter and which are marketing nonsense. Every scope I review gets mounted, zeroed, and shot at distances from 50 to 500 yards.

I run drop tests to check zero retention and measure MOA groupings to verify accuracy claims. I don’t accept money for reviews or sell products. This site exists because I got tired of buying garbage optics based on fake reviews.
