The Notos is Umarex’s compact .22 PCP carbine, built around an onboard air tank and a cocking lever instead of a break barrel. Two rifles share that name here, and they’re not the same gun. The original Carbine is the 7-shot model with an 11.75-inch barrel and a regulated tank. Gen 2 is the later spec: a 15-shot magazine, a 118cc tank filled to 3,625 PSI, and a Foster quick-connect port. Magazines, trays, and fill fittings follow those part numbers. Pick the rifle first, then buy parts that actually name that rifle.
Which Notos are you actually buying?
Start with the generation, not the nickname. The original Umarex Notos Carbine is the .22 with a 7-shot auto-indexing rotary magazine and an 11.75-inch barrel. Umarex quotes 700 fps with a 12 grain pellet, and the listing says the fixed HP tank is regulated for consistent shot-to-shot performance. Listed weight is 5 pounds.
Gen 2 is a different spec sheet. You get an improved 15-shot auto-indexing magazine (item number 2254872), a larger 118cc onboard tank with a 3,625 PSI max fill, a Foster quick-connect fill port, an updated SilencAir device, and a redesigned cocking lever. Power is quoted as up to 830 FPS with 11.9 grain pellets and up to 24 joules. Picatinny rail space and M-LOK slots at the 9 and 6 o’clock positions are on this listing, not the original.
If the product page will not tell you which generation it is selling, buy a different listing. The original spare magazine is part 2254848. Gen 2’s magazine is 2254872. Those are not the same part.
What do the fps numbers actually tell you?
Umarex publishes two speed claims, and they are not written the same way. The original Carbine’s number is 700 fps with a 12 grain .22 pellet from that 11.75-inch barrel. Gen 2’s number is up to 830 FPS with 11.9 grain pellets, plus energy up to 24 joules.
Those figures are tied to a named pellet weight. Change the pellet and the speed changes. A heavier hunting dome will not match the catalog number. For small game and backyard targets, both listings put the Notos in that job. Gen 2 is the one that publishes the higher speed and the only energy figure on this list.
Do not treat fps as a stand-in for shot count. Neither listing tells you how many shots you get per fill. The original at least says the tank is regulated, which is what you want for consistent velocity as pressure drops. Gen 2 does not mention a regulator on this listing.
How will you fill it?
A PCP with an empty tank does not shoot. Gen 2 is blunt about that: the 118cc cylinder ships empty with zero pressure, and the max fill is 3,625 PSI through a Foster quick-connect. You’ll need a hand pump, a compressor, or a filled air tank and a hose that ends in a Foster fitting.
The original Carbine listing does not publish fill pressure and does not name the fill fitting. That’s a real gap. If your hose is probe-style, the fill adapter on this list is the part to look at before you assume a Foster whip will click on.
Do not buy either rifle until you have priced the air supply. A pump that can reach 3,625 PSI is not a throw-in accessory. The rifle is the smaller check.
Do you want a magazine or a single-shot tray?
The original Carbine feeds from a 7-shot auto-indexing rotary magazine. Spare magazines are part 2254848. That’s a hunting cadence: load seven, shoot, reload.
Gen 2 includes one 15-shot magazine and one single-shot tray. More pellets before you dig in a pocket, plus a tray when you want to seat one pellet at a time.
The separate tray on this list is sold for the original Notos Carbine, item 2254847. Umarex’s pitch is accuracy: the pellet loads into the barrel with no chance of deforming the skirt. If groups matter more than follow-up shots, that’s the feed device. If you’re buying Gen 2, a tray already comes with the rifle, so check that box before you add another.
Different part numbers mean you should not mix magazines across generations and hope they index.
Umarex Notos Carbine Review
1. Umarex Notos Gen 2 .22 Caliber PCP Air Rifle – 15-Shot Magazine, 820 FPS
This is the later Notos, and the published spec is the reason to pick it. Umarex lists a redesigned cocking lever, an improved 15-shot auto-indexing magazine (item number 2254872), an updated SilencAir device, and a larger 118cc onboard tank. That tank fills to a maximum 3,625 PSI through a Foster quick-connect port, and it ships empty with zero pressure.
Power is quoted as .22 caliber pellets up to 830 FPS with 11.9 grain pellets, producing up to 24 joules for target shooting and small game. You get Picatinny rail space for an optic and M-LOK slots at the 9 and 6 o’clock positions. In the box you get one 15-shot magazine and one single-shot tray, so you can run it as a repeater or seat pellets one at a time.
If you want the higher published speed, the bigger magazine, and a Foster fill port you can match with a Foster hose, this is the Notos to buy. Plan the 3,625 PSI air source before the optic.
Best for: Shooters who want the 15-shot Notos with Foster fill and the higher published speed

2. Umarex Notos Carbine .22 Caliber PCP Pellet Gun Air Rifle
The original Carbine is the compact Notos with a published barrel length. Umarex puts an 11.75-inch barrel on it and quotes 700 fps with a 12 grain .22 pellet. The magazine is a 7-shot auto-indexing rotary, and spare magazines are part 2254848.
Side-lever cocking is the cycle: the listing calls it quiet and easy to shoot, with a smooth transition to the next shot. The fixed HP tank is regulated for consistent shot-to-shot performance, which is the feature the Gen 2 page does not mention. Listed weight is 5 pounds. Umarex names small game hunting, plinking, and target shooting as the jobs.
You don’t get extra magazine capacity, the Foster language, or a published fill pressure. Fine if you want the regulated compact carbine and you already know how you’ll fill it.

3. Umarex Notos Single-Shot Tray Magazine for Notos Carbine .22 PCP Air Rifle
This tray is cut for the original Notos Carbine, item 2254847, not a generic PCP feed device. Capacity is a single round. Umarex’s pitch is groups: the pellet loads into the barrel with no chance of deforming the skirt.
It’s easy to load and listed at 0.05 pounds. Keep it in the same pouch as a tin of pellets and swap it in when you’re shooting for accuracy instead of follow-up speed. If you already own the Carbine and you care about clean seating, this is the part. Gen 2 already includes a single-shot tray with the rifle, so don’t double up until you check that.
Best for: Original Notos Carbine owners who want single-pellet seating
Amazon currently shows this one out of stock — a temporary supply gap on a product that is still made, so it is worth checking back.
4. Air Fill QC Probe Adapter for Umarex AirSaber, AirSaber Elite X2 & Notos PCP Gun
If your Notos fills with a probe instead of a Foster nipple, this stainless-steel adapter turns a standard female quick-disconnect into a fill probe. The 8mm quick disconnect pushes into a standard female coupler, so it hangs off a normal PCP fill hose. O-ring seals come pre-installed, and you get two spare rubber o-rings in the package.
The listing names the AirSaber, AirSaber Elite X2, and Notos PCP. Gen 2’s rifle page specifies a Foster quick-connect fill port, so confirm which fill your gun actually has before you order a probe. A probe on a Foster gun doesn’t fill anything.
Best for: Notos owners whose gun takes a probe fill on a standard female QD hose

Frequently Asked Questions
Do I need a license to own a Notos?
Airgun rules vary by state and sometimes by city. Check yours before you buy, especially if you plan to shoot inside town limits or hunt small game with it.
Can I put a Gen 2 magazine in the original Carbine?
The listings use different part numbers. The original spare magazine is 2254848. Gen 2’s magazine is 2254872. Do not assume they swap or index.
Does the Gen 2 tank arrive ready to shoot?
No. Umarex says the 118cc tank ships empty with zero pressure. You need a fill source that can reach 3,625 PSI before the first shot.
Is the original Notos regulated?
The original listing says the fixed HP air tank is regulated for consistent shot-to-shot performance. The Gen 2 listing does not mention a regulator.
What pellet weight matches the catalog speeds?
Gen 2’s speed claim is with 11.9 grain pellets. The original’s is with a 12 grain pellet. Start there, then try the wadcutters or domes you actually want to shoot. Heavier pellets will run slower.
We’ll say it plainly. Buy Gen 2 if you want the 15-shot magazine, the Foster port, and the higher published speed and energy. Buy the original Carbine if you want the regulated 5-pound gun with the 7-shot mag and you already have a plan to fill it. Either way, budget the air first. Then match the magazine, tray, and fill probe to the exact rifle you ordered, not to the Notos name on the box.
