  • Rifled steel barrel with SilencAIR integral silencer

  • 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:Lovely Accuracy, like it should be. Got this to replace a Beeman Kodiak X2 whose accuracy was frustrating me. Wow nice open sights. But my eyes these days need optics. Scope turrets hand adjustable, yes! This rifle hits hard! looks like it embedded halfway into 2x6 backdrop. Blasted thru a sun baked pork rib bone no problem. Much less gyrating in recoil than that Beeman Kodiak Steel Springer. Love the thumbhole stock.
Things I would have changed:Would like the safety to be push-away from trigger to be off position. Seems bass-ackwards the way they have it. But certainly not a deal breaker. The instructions warn you not to grab the barrel on the silencer in order to cock it as could damange the silencer. Only problem is this leaves less barrel length for leverage, and makes for a nice hefty cocking force. It works your lats and abs cocking this rifle. Probably get easier over time, but not by much I imagine.
What others should know:Somebody else wrote a little front-end heavy, and yeah... I could see why they said that. Definitely is a lil bit once the scope is on. People complaining about slings... just get a Kifaru Gun-bearer for your pack when you go in the field. Again, the accuracy... literally right out of the box, has me very excited. And the power this thing has is exciting! Can't wait to see what it does to feathers and fur!

Things I liked:Firstly I must tell you that I read Tom Gaylord's review of this rifle and was suitably impressed. The Reaxis gas piston [reversed] was a novel idea and worth looking into. Regretfully, after receiving it via FedEx, I only fired 6 pellets [H&N FTT] through it. Cocking this rifle horrified me; the grinding sounds of sand on metal as I cocked the Reaxis piston sounded like someone had put a hand full of sand in the piston. Umarex QC? I don't know. I never did get the opportunity to try the scope, which got rave reviews as well. Using the open sights at a range of 25meters, I was unable to lower the sights sufficiently to even come close to a group, because I had to mash my cheekbone down hard on the stock to even try to align the Tru-glo dots. It appeared like the combing of the stock was inline with the barrel and therefore too high to use the open-sights.
Things I would have changed:I'd have liked to see a thumbhole stock similar to the Benjamin NPXL or the Hatsan 125TH stock. Both very comfortable to shoot. As for the grinding problem, I think I would have liked to have $20.00 extra [20 for 20], so that Pyramyd Air might find out the cause before it was sent to me, then returned for credit.
What others should know:Ergonomics:The applied science of equipment design intended to reduce operator fatigue and discomfort. The first and most important criteria in manufacturing, be it a motorcycle, a car, a recliner chair or an air rifle. If you can't get past the comfort stage, the rest is immaterial. Looking over the rifle before I even cocked it the first time, I was impressed with the quality of manufacture, but somewhere between the end of the assembly line, and it's arrival at my place, there was an empty hole where the FINAL INSPECTION should have been. No blame intended here because I may have just got a rifle that was missed, but If I'd have cocked this near my wife, she would have been looking for the fingernails and the chalkboard!!! I'm sorry; really sorry, because I did look forward to this rifle after reading B.B.Pelletier's review. Instead, I purchased my third Hatsan 125 Black [this time in .25 cal].

  • Paulette from USA asked:

    How does the included scope hold up to the recoil?

    • JimPysht from USA:

      My AO 40 failed, presumably from the shock. Other scopes (and a BSA Red Dot held up. But bottom line for me (see my review) is that an Octane .22 simply cannot be held - "Artillery Hold" to near vise-grip. My Octane purchased a yr-ago (2nd, actually to replace a bummer 1st purchase)and don't know if the current Octane is made the same.

  • 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
