Two air rifles from the same brand, yet they represent fundamentally different approaches to modern shooting. The Umarex Notos is a traditional regulated PCP carbine, a compact powerhouse built for efficiency. The Umarex Komplete NCR N2 is a radical departure, a CO2 powerlet system reimagined with high-pressure nitrogen. This isn’t just a caliber debate; it’s a clash of philosophies on power, convenience, and the very future of airgunning.
between them means deciding what you value most: the proven, refillable consistency of PCP or the grab-and-go simplicity of a disposable cartridge. Honest to goodness, your intended usebackyard plinking, pest control, or casual target shootingwill heavily sway your decision. Let’s break down where each rifle excels.
Two Different Umarex Philosophies
Umarex has built a reputation for innovation, and these two models are perfect examples. The Notos follows a refined, minimalist path. It takes the established PCP formulaa fixed air tank, a regulator, a side-lever actionand pares it down into an incredibly handy package. Its integrated suppressor and short barrel scream practical utility.
The Komplete NCR N2, on the other hand, is a bold experiment. It asks: what if you could have PCP-like performance without the pump or compressor? Its answer is a single-use NitroAir cartridge rated at 3,600 psi. A patent-pending system pierces and regulates this down to a steady 1,800 psi for each shot. Its a fascinating hybrid, aiming to bridge the gap between CO2 convenience and PCP power. From my honest perspective, this makes it a compelling option for newcomers wary of the initial PCP infrastructure investment.

The Notos’s shorter barrel length contributes to its carbine handling, while the Komplete’s included 4×32 scope on a Picatinny rail offers out-of-the-box readiness. The difference in overall weight isn’t specified, but the Notos’s compact form likely makes it lighter. Speaking honestly, the Komplete’s higher listed energy comes from its lighter, faster .177 pellet, a crucial factor for penetration versus the Notos’s heavier .22 projectile.
Performance & Accuracy: PCP vs N2 Power
This is where theory meets the target. The fps velocity numbers tell only part of the story. The Notos, as a regulated PCP, promises exceptional shot-to-shot consistency. That regulator ensures the first shot and the last from a fill have nearly identical power, which is the bedrock of long-range accuracy. Its 700 fps with a 12-grain .22 pellet is a sweet spot for efficiency and knockdown power.
The Komplete NCR N2 also boasts an internal regulator, smoothing the nitrogen release to 1,800 psi per shot. Its 1,025 fps muzzle velocity is impressive, but remember, that’s with a very light 7-grain .177 pellet. The higher foot-pound energy suggests strong potential for penetration, but the lighter pellet can be more susceptible to wind drift. My honest take is that the Notos’s .22 caliber might offer more stable flight in breezy conditions, a key consideration for pest control.
Both rifles are multi-shot repeaters, eliminating single-shot fuss. The Notos uses a 7-shot auto-indexing rotary magazine, while the Komplete includes two 12-shot magazines. A higher shot count per load is a clear win for the Komplete on paper. However, the long-term cost and availability of its proprietary N2 cartridges versus filling a standard PCP tank is a major practical difference.
Trigger Pull, Noise Level, and Feel
User experience extends beyond ballistics. The Notos employs a side-lever cocking mechanism described as smooth and quiet, allowing fast follow-up shots. The noise level is minimized by its integrated design. The Komplete’s bolt action (inferred from its removable magazine) is likely straightforward, and its SilencAir Technology also promises reduced report.
Trigger pull specifics aren’t listed for either, but regulated actions typically offer cleaner, more consistent breaks than unregulated ones. The Komplete’s included scope gives it an immediate advantage for hitting targets, whereas the Notos requires you to source your own optics.

Ideal Use Cases & User Scenarios
So, which rifle is for you? The answer lies in your typical shooting environment and patience for setup.
The Umarex Notos is ideal for:
- Backyard Shooting & Plinking: Its compact size, integrated quietness, and .22 caliber make it a fantastic, low-disturbance option for casual target practice. It’s a strong contender for best Umarex air rifle for pest control at closer ranges due to its caliber.
- The Shooter Who Owns a Pump/Compressor: If you’re already in the PCP ecosystem, the Notos is a brilliantly simple addition. Its regulated performance is ready to leverage your existing gear.
- The Hunter Valuing Stealth and Simplicity: Its carbine format and quiet operation are perfect for moving through brush or setting up for squirrels and rabbits.
The Umarex Komplete NCR N2 is ideal for:
- The Newcomer or Casual Shooter: Its “komplete” packagerifle, scope, magazinesand lack of needed support equipment make it the ultimate out-of-the-box airgun. No pumps, no tanks, just a cartridge.
- Shooters in Variable Climates: Nitrogen performance is stable across hot and cold temperatures, unlike traditional CO2. This is a huge advantage for year-round reliability.
- Those Prioritizing Low Maintenance: The nitrogen leaves no residue, promising a cleaner internal system and extended life with less cleaning.
The debate over which is more accurate Notos or Komplete N2 often comes down to the shooter. The Notos’s regulated .22 platform has inherent accuracy potential, but the Komplete’s included scope lets you start shooting accurately immediately, without extra cost. For formal target practice, resources like the official source for international shooting sports provide great guidance on technique.
Final Verdict & Purchase Recommendation
This comparison between a CO2 vs PCP hybrid and a purebred PCP carbine highlights there’s no universal “best.” There’s only the best for your situation.
Choose the Umarex Notos Carbine if: You value the long-term economy and consistency of the traditional PCP platform. You already have a way to fill air tanks, or don’t mind the initial investment in a hand pump. You prefer the potentially more stable ballistic performance of a .22 caliber for hunting and live in an area where backyard noise is a concern. Its design is focused, efficient, and proven. For another look at a compact PCP contender, our gamo Varmint analysis is worth a read.
Choose the Umarex Komplete NCR N2 if: Your top priority is convenience and immediate fun. You want to skip the PCP learning curve and ancillary gear entirely. You’re a casual plinker or new hunter who values a ready-to-shoot package and the consistent performance of nitrogen in any weather. You’re okay with the ongoing cost of consumable cartridges for the sake of ultimate simplicity.
In my honest opinion, I believe the Notos is the smarter long-term investment for a dedicated shooter. Its operating costs are lower, and it ties you into the versatile, standardized world of PCP airguns. However, the Komplete NCR N2 is a revolutionary product that lowers the barrier to entry for high-performance airgunning like never before. It genuinely lives up to its “komplete” name for a new shooter. To be completely honest, your decision hinges on whether you see airgunning as a hobby you’ll build upon (favoring the Notos) or a spontaneous activity you want to enjoy with zero fuss (favoring the Komplete). For more straightforward, no-nonsense reviews like this, the team at Honest Opinion is always on the case.
Both are exceptional in their own lanes. The Notos refines the expected; the Komplete N2 redefines what’s possible. Your next shot depends on which future of shooting you want to experience.
