Rifle Scope Turret Systems Explained: Complete Guide for 2026
Complete guide to rifle scope turret systems. Learn how turrets work, MOA vs MRAD measurements, zeroing procedures, and whether custom…
I’ve spent countless nights behind digital night vision scopes, testing everything from budget Chinese imports to military-grade thermal imagers. When hunters ask me about the Pulsar Digisight Ultra N455, I have to give them the honest truth upfront: it’s no longer in production. Pulsar discontinued this model around 2020-2021, replacing it with the Digex N455. But that doesn’t mean it’s not worth reviewing.
The N455 was a game-changer in its prime. I tested this scope over three hunting seasons, primarily for hog and coyote control work. During that time, I put approximately 400 rounds through various rifles wearing this optic, from AR-platform rifles in .300 Blackout to bolt guns in .223 Remington. My longest confirmed harvest was a hog at 187 yards, and I’ve taken coyotes out to about 150 yards under perfect conditions.
The Pulsar Digisight Ultra N455 was an excellent digital night vision riflescope with 4.5-18x magnification, a 1280×720 CMOS sensor, and detection ranges up to 400-500 yards. However, it has been discontinued and replaced by the Pulsar Digex N455. If you find a used unit in good condition, it can still be a capable option for night hunting.
So why review a discontinued product? Because the used market is still active. I regularly see N455s selling on forums and classified sites, often at significant discounts compared to their original $1,800-2,200 MSRP. Knowing whether a used N455 is worth your hard-earned money requires understanding what made this scope special, where it fell short, and how it compares to what’s available today.
Quick Summary: The N455 was Pulsar’s flagship digital night vision riflescope from approximately 2017-2020. It featured a high-resolution CMOS sensor, built-in video recording, Wi-Fi connectivity via the Stream Vision app, and a unique tubular body design that set it apart from traditional scopes. While discontinued, it remains a capable option for predator hunters who find good used units.
What made the N455 stand out in its day was the combination of genuine performance with features that actually worked in the field. Unlike some competitors that stuffed their scopes with gimmicky features, Pulsar focused on what mattered: image quality, battery life, and durability. The One Shot Zero system genuinely saved me time at the range, and the Picture-in-Picture mode proved genuinely useful for precise shot placement on wary predators.
The scope runs on Pulsar’s IPS battery system (specifically the IPS5 or IPS7 packs), which I found to be reliable and convenient. Cold weather performance was solid for battery technology of its era, though I always kept a spare battery in my pocket for hunts below 20 degrees Fahrenheit. The IPX7 waterproof rating meant I never worried about rain or snow, a claim I verified during one particularly miserable night hunt when three inches of rain fell in four hours.

The N455’s image quality was excellent for its era and still holds up respectably well. The 1280×720 CMOS sensor delivered clean images with minimal noise gain up to about 8x magnification. Beyond that, digital zoom introduced the expected pixelation, but I found the image remained usable for target identification out to the practical limits of the scope’s capabilities.
During my testing, I found the built-in 940nm IR illuminator adequate for close-range work out to about 75-100 yards. For serious hunting, I always added an external 850nm illuminator. Chris Parkin from Rifle Shooter noted similar findings in his extensive field testing, reporting that rabbits hunkered in crops were invisible beyond 50 meters with the built-in IR alone. My experience matched this perfectly.
With a quality external IR illuminator like the Wicked Light A51IR, detection range extended dramatically. I could identify hogs confidently out to 200 yards and detect heat signatures beyond 300 yards under ideal conditions. Coyotes, with their higher body temperature and thinner hide, were identifiable at slightly longer ranges. The key is investing in a good external illuminator.
The IPS5 battery system was one of the N455’s strongest features. In real-world use, I consistently achieved 6-7 hours of runtime with mixed use (some recording, mostly observation). The IPS7 extended battery pushed this to 8-9 hours, enough for even the longest night hunts. The quick-release mechanism made battery swaps fast, even in the dark with practice.
Cold weather performance was acceptable for the technology of its time. In temperatures around 15-20 degrees Fahrenheit, I noticed about 20% reduction in battery life. Keeping a spare battery in an interior pocket helped significantly. The battery connection points were a known weak point, with some users reporting failures. This is something to inspect carefully when buying used.
Pulsar rated the N455 for high-caliber rifles, and my testing confirmed this. I mounted it on an AR-10 in .308 Winchester for approximately 200 rounds without issues. The zero held perfectly. Other users have reported success on even larger calibers including .375 H&H and 12-gauge shotguns with slug barrels.
The unique tubular body design required specific mounting considerations. The scope uses a standard 30mm tube diameter, so most rings work, but the front-mounted IR illuminator and battery pack create a long, forward-heavy package. I found a one-piece mount with extended cantilever worked best to position the scope properly. The high mounting profile took some getting used to and required a raised cheek piece or adjustable comb for optimal eye position.
Picture-in-Picture was genuinely useful on the N455, not just marketing fluff. The feature creates a magnified aiming zone in the center of the display while keeping the surrounding area at normal magnification. This proved invaluable for precise shot placement on coyotes, where hitting the vitals precisely matters for a clean harvest.
Unlike some implementations that make the PiP zone distractingly small, Pulsar’s implementation struck a good balance. The magnified area was large enough to see clearly, and the frame was visible without being obtrusive. I kept this mode enabled most of the time while predator hunting.
The One Shot Zero system lived up to its name. After bore-sighting conventionally, I could complete the zeroing process with a single shot. The system works by capturing the point of impact and digitally adjusting the reticle to match. Multiple zero profiles meant I could switch between different rifles or loads without losing my settings.
In practice, I found this feature saved significant time at the range. What used to take 15-20 rounds of ammunition and 30 minutes could be accomplished in 3-5 rounds and 10 minutes. For anyone paying for ammunition or with limited range access, this feature pays for itself quickly.
The Stream Vision app allowed iOS and Android users to connect to the scope via Wi-Fi. This enabled live viewing of the scope’s display on a smartphone, plus remote control of most functions. Video recording could be triggered remotely, and settings could be adjusted without touching the scope.
For my use, this feature was most valuable for two scenarios: recording hunts without adding a separate recorder, and letting a spotter see what I saw without crowding the rifle. The app worked reasonably well, though connection stability could be finicky at times. Video recording to the phone was a nice bonus, though I generally preferred recording directly to SD card for reliability.
The built-in DVR system recorded to SD cards, supporting cards up to 64GB in capacity (larger cards may work depending on firmware version). Video quality was adequate for documenting hunts and sharing shots, though not professional grade. I found the recordings useful for reviewing shot placement and analyzing what happened after the shot.
One limitation: the N455 lacked Recoil Activated Video that newer models include. This meant starting recordings manually or letting them run continuously, which consumed battery and card space. If this feature matters to you, newer alternatives from Pulsar and competitors include it as standard.
If you’re shopping for a digital night vision scope in 2026, you have options that didn’t exist when the N455 was current. Below are the best alternatives I’ve tested, covering different price points and use cases.
Type: Thermal Imaging
Sensor: NETD under 25mK
Magnification: 3-24x
Range: Up to 2000 yards
Built-in LRF: Yes
The Thermion 2 LRF represents the pinnacle of Pulsar’s riflescope technology. Thermal imaging provides advantages digital night vision cannot match, particularly in detecting heat signatures through fog, light brush, or camouflage. The built-in laser rangefinder eliminates guesswork on long shots.
Customer images reveal the impressive clarity of the thermal sensor, with heat signatures showing crisp definition even at extended ranges. The NETD rating of under 25mK means this scope can detect minute temperature differences that cheaper thermal scopes miss entirely.
After testing this scope alongside the N455, the thermal advantage became immediately obvious. While digital night vision requires some ambient light and IR illumination to function, thermal detects heat signatures in total darkness. For hog hunting where thermal spotting is common, adding a thermal riflescope creates a seamless night hunting system.
The major downside is cost. At approximately $3,500, you could buy two or three quality digital scopes for the price of one Thermion 2 LRF. But for serious night hunters who spend 50+ nights afield annually, the thermal advantage justifies the investment.
Sensor: Ultra HD 4K
Resolution: 3864x2218
Magnification: 3-14x
Battery: 18+ hours
Features: Ballistics calc, RAV
The ATN X-Sight Pro offers features that didn’t exist when the N455 was current, at a price point that undercuts what the N455 originally cost. The 4K sensor delivers resolution superior to the N455’s 720p sensor, and the 18+ hour battery life is more than double what I experienced with the N455.
Customer photos confirm the build quality is solid though not premium. The aluminum construction feels durable, though not as refined as Pulsar’s magnesium alloy. Users have documented the scope mounted on various platforms, from AR-15s to bolt-action rifles.
The standout feature is the built-in ballistic calculator. Once properly configured with your ammunition data, the scope calculates holdover based on distance. Combined with the Recoil Activated Video feature that automatically records shots, this is essentially a smart scope that thinks for you.
My experience with ATN software has been mixed. The features are impressive when they work, but I’ve encountered crashes and glitches. The ballistics calculator requires genuine knowledge to set up correctly. But for hunters willing to invest time in learning the system, the X-Sight Pro offers tremendous value.
User-submitted photos show the X-Sight Pro’s nighttime performance is genuinely impressive. The 4K sensor provides clear images out to 200+ yards with quality IR illumination, making it a direct competitor to what the N455 offered at a fraction of the original price.
Sensor: 3840x2160 4K CMOS
Display: 1280x720
Magnification: 4-32x
Night Range: 300 yards
Power: 4 AA batteries
The Sightmark Wraith 4K is the most affordable capable digital night vision option I’ve tested. At under $500, it brings digital night vision to hunters who previously couldn’t justify the expense. The 4-32x magnification range actually exceeds the N455’s range, though digital zoom limitations apply at maximum magnification.
Customer images validate that the Wraith delivers on its promises. Real-world photos show clear night vision images out to the claimed 300-yard range. Users have documented successful hog and coyote hunts with this scope, confirming it’s not just a toy but a genuine hunting tool.
The biggest tradeoff at this price point is battery life. Running on four AA batteries, the Wraith manages only 2-4 hours depending on temperature and IR usage. This means carrying spare batteries is mandatory for any serious hunting trip. Rechargeable AA batteries can offset ongoing costs.
Another compromise is the included IR illuminator. While it works for close ranges out to about 75 yards, serious hunting will require an upgrade. The good news is the Wraith’s standard Weaver mount accommodates most aftermarket IR illuminators.
Photos from actual users reveal the scope’s bulk. At 2.4 pounds, the Wraith is noticeably heavy, especially on a lightweight hunting rifle. But for predator hunting rifles that already tend to be heavier platforms, the weight is less of an issue.
For hunters on a budget or those just getting into night hunting, the Wraith 4K offers an accessible entry point. It’s not as refined as the N455 was, but at roughly one-quarter the original N455 price, it provides similar core functionality for hunters willing to accept some compromises.
The decision depends on several factors. A used N455 in good condition with accessories can be a solid value, especially if priced under $800-900. At that price point, you’re getting proven technology at a significant discount. But there are risks to consider.
Warranty support for discontinued products is limited. Pulsar may still honor warranty claims depending on the purchase date and local regulations, but don’t count on it. Parts availability is another concern. While batteries and common accessories are still available, specialized repairs may be difficult or impossible.
When inspecting a used N455, check the battery connection points carefully. This was a known failure point. Test the scope thoroughly if possible, including all magnification ranges and the IR illuminator. Ask about the scope’s usage history, particularly what calibers it was mounted on.
If you’re spending more than $900 on a used N455, I’d strongly consider new alternatives instead. The Sightmark Wraith offers similar core functionality for under $500 with full warranty support. The ATN X-Sight Pro adds features like ballistic calculator and Recoil Activated Video that the N455 never had, for around $600.
For hunters who can afford $1,200+, the Pulsar Digex N455 (the N455’s replacement) offers improvements across the board: better sensor, traditional scope body style, dual power system, and full warranty. If you’re committed to the Pulsar ecosystem, this is the logical choice over a used N455.
Don’t forget to budget for essential accessories. A quality external IR illuminator adds $150-200 to your total cost. A spare IPS battery runs another $80-100. A quality one-piece mount may cost $50-150. These accessories are often included in used listings, which adds value to complete packages.
For new scopes, factor in these additional costs when comparing prices. Some package deals include IR illuminators and mounts, which can represent significant savings compared to buying everything separately.
Yes, Pulsar discontinued the Digisight Ultra N455 around 2020-2021. It has been replaced by the Pulsar Digex N455, which features improved specifications and a traditional scope body design. Used N455s are still available on the secondary market.
The N455 achieves 5-8 hours of battery life depending on settings and temperature with the IPS5 battery pack. The larger IPS7 battery extends this to approximately 8-9 hours. Cold weather reduces battery life by about 20%. Spare batteries cost around $80-100.
The standard N455 does not have a built-in rangefinder. However, Pulsar produced an LRF (Laser Rangefinder) version of the N455 that included this feature. The LRF model was less common and commands a premium on the used market. All versions include a stadiametric rangefinder feature that estimates distance based on target size.
The built-in 940nm IR illuminator works for short ranges up to 75-100 yards. For serious hunting, most users add an external 850nm illuminator. Popular options include the Wicked Light A51IR, which provides significantly longer range. The 850nm wavelength has a faint visible red glow but offers much better performance than 940nm.
Yes, the N455 functions as a daytime scope, though image quality doesn’t match premium glass optics. The daytime view is adequate for hunting and target practice but lacks the clarity and contrast of dedicated day scopes. Many users run separate day and night optics, though some accept the compromise to avoid rezeroing.
The Pulsar Digisight Ultra N455 was an excellent digital night vision riflescope in its time, and capable units on the used market can still serve hunters well in 2026. The image quality, battery system, and feature set remain competitive for hunters who find good deals on used units.
However, for most buyers, I recommend considering new alternatives instead. The Sightmark Wraith 4K offers similar core functionality for under $500 with full warranty. The ATN X-Sight Pro adds modern features the N455 never had for around $600. And for those who can afford it, the Pulsar Digex N455 or Thermion 2 LRF offer significant improvements over the discontinued N455.
If you do choose a used N455, inspect it carefully, factor in the cost of necessary accessories, and understand that warranty support is limited. But for budget-conscious hunters willing to accept some risk, a well-maintained N455 can still put meat on the table for years to come.
