Two airguns sit on the table, each representing a distinct philosophy in the world of recreational shooting. The Umarex Notos Carbine embodies a purpose-built tool, a compact hunter. The DPMS Full Auto SBR, on the other hand, is a pure expression of tactical fun. They share the same fundamental goallaunching a projectilebut their approaches couldn’t be more different. Choosing between them isn’t about “best” airgun, but identifying which one aligns with your specific goals for noise, power, and sheer enjoyment.
This comparison cuts through the marketing to focus on what these rifles actually deliver. We’ll pit the quiet efficiency of a Pre-Charged Pneumatic (PCP) system against the instant gratification of a CO2 Cartridge platform. From First Shot Velocity (FSV) consistency to the realities of backyard use, well provide the clear contrast you need. My honest assessment is that most shooters will instinctively lean towards one camp after se core differences.
Head-to-Head: Specifications at a Glance
Before diving into nuances, a side-by-side look at the hard numbers establishes the baseline. This table outlines the fundamental specs that define each rifle’s capability and character.

Power Source & Performance Deep Dive
The heart of this comparison lies in the powerplant. The Notos uses a filled, regulated air cylinder, while the DPMS runs on disposable gas. This fundamental difference dictates everything from pellet velocity to your long-term shooting routine.
The PCP Precision of the Umarex Notos
Charged to high pressure (typically 3000 PSI), the Notos’s internal air reservoir provides consistent, regulated power. It launches a substantial 12-grain .22 pellet at 700 fps. The regulated system is keyit ensures the First Shot Velocity (FSV) is nearly identical to the last, which is critical for accuracy. The side-lever cocking is smooth and the report is notably quiet, making it neighbor-friendly. Honestly speaking, the trade-off is the need for an external filling source: a hand pump, scuba tank, or compressor, which adds to the initial setup cost and effort.
The CO2 Thrill of the DPMS DSBR
The DPMS is fueled by two standard 12-gram CO2 Cartridges, offering plug-and-play simplicity. It propels lightweight steel BBs at up to 430 fps. The performance here is less about precision and more about experience. The full-auto capability, with a blistering 1400 rounds per minute, is purely for recreational spraying. Speaking honestly, CO2 power is notoriously temperature-sensitive; velocity and shot count drop significantly in cooler weather. Its also a Magazine-fed system, but for BBs, facilitating its high-rate-of-fire design.
Covering the : Noise and Temperature
Competitors often skip two critical practical factors. First, noise level: the Notos, with its shrouded barrel and PCP mechanics, is significantly quieteroften a decisive factor for suburban shooters. The DPMS has a sharper, more pronounced report. Second, temperature sensitivity only affects the CO2 rifle. A 60F day versus a 40F day can mean a 50+ fps drop in velocity for the DPMS, while the PCP system remains completely stable.
Ideal Use Cases & Target Applications
These rifles are built for different missions. Your intended usewhether it’s the Umarex Notos PCP for small game hunting or the DPMS DSBR CO2 rifle for backyard plinkingwill point you to the right choice.
Where the Umarex Notos Excels
The Notos is a practical, compact tool. Its .22 caliber pellet, higher energy, and inherent accuracy make it suitable for:
- Small game hunting: The 700 fps muzzle energy is ethical for pests and small game at reasonable ranges.
- Quiet target shooting: The low report and consistent shot cycle are ideal for disciplined practice.
- Pest control: Where power and discretion are needed.
Its a rifle for the shooter who values shot-to-shot consistency and is willing to manage the air supply. From my honest perspective, it bridges the gap between entry-level and serious airgunning without a huge price leap. For another look at a capable PCP, see how it stacks up against a popular gamo alternative.
Where the DPMS Full Auto SBR Shines
The DPMS is the definition of fun-focused shooting. Its AR-15 style ergonomics and blistering rate of fire are perfect for:
- Backyard plinking: Soda cans, reactive targets, and general “smile factor” shooting.
- Tactical training simulation: The handling and controls mimic a real firearm for safe, affordable handling practice.
- Pure entertainment: The full-auto feature is a unique thrill few other affordable airguns offer.
Its about the experience, not tiny groups. If you want my honest opinion, the DPMS wins on immediate gratification and social shooting fun. Its also worth comparing its approach to other tactical platforms like this gamo model.
The Real Cost: Price, Value, and Operating Expenses
The sticker price is just the beginning. The true cost per shot PCP vs CO2 rifle reveals a lot about long-term value.
The DPMS typically has a lower initial cost. But you must continually buy CO2 cartridges and BBs. The cost per shot, while still low, adds up over time, especially with full-auto use. The Notos requires a higher upfront investment, not just for the rifle but for a filling method (a hand pump is the most common starter). However, once filled with air (which is essentially free after the equipment purchase), the cost per shot is just the pelletmaking it extremely cheap for high-volume precision shooters in the long run.
Final Verdict & Recommendation Guide
So, which is more accurate Notos or DPMS? That’s almost the wrong question. Accuracy implies a precision tool, which is the Notos’s domain. The DPMS is about fast, reactive shooting fun.
Choose the Umarex Notos PCP Carbine if:
- You prioritize accuracy and consistency for hunting or target shooting.
- Quiet operation is a necessity for your shooting environment.
- You’re willing to invest in a hand pump or compressor for the long-term benefit of nearly free air.
- You value a compact, purpose-driven design over tactical aesthetics.
Choose the DPMS Full Auto SBR if:
- Your primary goal is recreational plinking and having a blast with friends.
- You love the realistic tactical feel and the thrill of full-auto capability.
- You want the simplest possible setupjust insert CO2 and BBs and shoot.
- Initial budget is a primary concern and you don’t mind ongoing consumable costs.
Both are excellent at what they do. The Notos is a serious air rifle disguised as a carbine; the DPMS is an incredibly fun replica that shoots. My honest take is that for the shooter seeking a versatile, capable tool that can hunt and target shoot with authority, the Notos is the compelling choice. For the shooter who wants maximum fun with minimal fuss, the DPMS is unbeatable. Always remember to follow local laws and safety guidelines, and consider formal training from an official source to improve your skills.
At the end of the day, your perfect airgun matches your intention. Whether it’s the disciplined thump of a .22 pellet on target or the ringing symphony of a BB on a steel spinner, the right choice brings satisfaction. That’s the Honest Opinion from this side of the table.
