  • 3.50 lbs. trigger-pull
  • Fiber-optic sights (fully adj. rear)

Here are the benefits of the Umarex ReAxis gas-piston:
  • Smoother cocking
  • Smoother shooting
  • No spring torque
  • No spring fatigue, even if you leave it cocked for hours
  • Functions perfectly in cold weather
  • Lasts longer than a metal spring

While gas-pistons (also known as gas springs and gas rams) were originally touted as beneficial for airgun hunting since you can leave your gun cocked without fatiguing a metal spring, that's not the only reason you'd want a gas piston. Anyone who enjoys a smooth spring rifle should try a gun with a gas piston. Once you do, you won't ever want to go back to a gun with a metal spring!

Another point you'll want to remember about the Octane spring rifle is the 3-year warranty. While most guns with gas pistons have a one-year warranty, Umarex goes the distance. Because some shooters are hesitant to try a technology new to them, they worry about support. The extra two years of warranty should take care of those concerns.

Things I liked:Build quality is great. solid and heavy, which leads to stability. Value for the performance is very good. The scope seems to be well built and I would call a 3x9 AO with parallax adjustment overkill for a pellet rifle.
Things I would have changed:I would like a hood over the front sight but alas, once you add the scope, you don't need the open sights. The cocking effort is much too large. I saw the video of a reviewer cocking from a sitting position, I have not been able to do that. I have to jack it while standing. It's a beast to cock.
What others should know:Louder than expected for the first 10 shots. After 50 shots, it became a bit quieter DO NOT push a loose pad through the barrel from the breech as you could lose it in the noise suppressor. I got one pad stuck in the first chamber and it took 15 minutes of shaking and pushing back from the front to get it out again. Accuracy is good, about 3/4" from 25 yards from standing position using the scope. Never bench rested and fired, I expect better.

Things I liked:I find this to be a very good air rifle for the money. The scope it comes with is far better than the 3X9X40 that came with my Gamo Whisper Fusion Elite. Very powerful. With H&N Field Target Trophy 14.66gr very accurate. My Octane is .22 cal
Things I would have changed:The only thing I would change is the trigger pull I had to adjust mine from factory as it was hard to pull after my adjustment it is fine. And I would try to reduce the overall weight as it is quite heavy
What others should know:I would not buy this for a younger shooter. Only because it does take some force to cock and it is heavy

Things I liked:After purchasing 3 from different sellers and sending all three back for manufacturing defects... I have nothing good to say about this product... First rifle had a bent barrel and a bad RAM seal, second rifle had a bent barrel worse than the first and a defective safety, 3rd rifle showed up with the front fiber sight missing, a blown out breach seal even though I had not shot the gun yet, and the barrel was bored off center... FedEx this one back to pyramid air over a week ago, received no tracking number have yet to even receive an email confirming they received my shipment... Not a happy customer at the moment.
Things I would have changed:Everything.. Avoid this product
What others should know:Spend three to four hundred dollars on a real air rifle and you will be happy

  • Paulette from USA asked:

    How does the included scope hold up to the recoil?

    • steve from USA asked:

      I cave a .22 cal. Crosman Nitro Venom. How does this rifle compare in accuracy and power?

      • Chevota from USA:

        Hard to compare since chinese guns vary drastically in those areas so you'd need to take an avg estimate because a single gun of each will do little good. This will have more power than the Venom because the Octane is a physically larger magnum class gun and the Venom is not. The quality of the bore in my Octane is better than most Crosman and other cheaper airguns, and a great many people are very happy with the accuracy. So it's more powerful and probably more accurate on average. There are other pros/cons with each gun too, like the Octane's size and weight, price, cocking effort, and a trigger with little room for improvement. The Crosman trigger is not good either but can improved drastically, and since there are plenty of inexpensive and interchangeable parts for the Crosman, repairs and improvements are cheap. The Octane is much harder, maybe impossible to find parts for, and if available they're no doubt much more expensive. My solution is/was to buy both guns. I think .22 is the best match for the Octane's power, and the .177 a better match for the Venom. Changing the caliber on the Crosman is another bonus, which you can do to yours if you want for cheap. The Trail XL is a Crosman magnum so a little better comparo, and the XL will on avg make more power than this.

    • Asad from USA asked:

      do wee need to fill Gas every time we use this gun ?

      • Chevota from USA:

        I think what thru you off is the "Gas"-Piston? It's really a gas spring, which simply replaces the coil spring this design used before. Instead of compressing a steel spring it compress a gas one, and like the steel one you use it over and over. The gas spring is very much like the ones used on many car and SUV hatchbacks to support the doors weight when open. So no you don't need to charge it with gas or air, it simply replaces a long coil spring. There are youtube vids and airgun mfg vids to look at too.

      • michael from USA:

        t is charged by a single stroke break barrel action. You cock the barrel, load the pellet, close and shoot. This is not a pcp
