  • 3.50 lbs. trigger-pull

  • Includes 3-9x40 AO scope (10 yds to infinity parallax adjustment, duplex reticle) and mount (scope is not mounted)

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:I got this rifle in .22 and it arrived on time as scheduled. Rifle appears rock solid and the scope was easy to install with the included Weaver scope rings. This is a very powerful air rifle.
Things I would have changed:With an air gun of this quality, I think a few things could set this rifle apart. Sling mounts, small packs of test pellets with cleaning pellets would all be nice additions.
What others should know:First 5-10 shots are very loud akin to a 22LR. After these first shots, the rifle gets a LOT quieter. Scope was relatively easy to sight....out of the box stabilize the rifle with the crosshairs on target and fire 5 shots, then adjust the scope settings so that crosshairs are now centered on your grouping. Keep doing this until bullseye is achieved. I did this at 20 yds. My rifle loves the CHWP and accurate

Things I liked:This rifle was rock solid out of the box. Checked all screws which were all tight and easily installed the scope with provided Weaver scope rings and Picatinny rail. The scope was relative easy to sight in and I see nothing wrong with the trigger. My rifle seem to love the Crossman Premier HPs (6.47 at Wally world)
Things I would have changed:I would add a sling or at least rings for a sling as this rifle is just under 10 lbs and could be a load in the field. Umarex should also include a sampler pack of pellets including some clean out pellets...would be shipped and ready to shoot and would allow consumers to test a pellet of their choosing.
What others should know:The first 5 shots are rather loud....I shot mine and immediately looked around to see if neighbors or police were curious in the neighborhood. After these gun gets much quieter and the cocking gets a bit easier also.

  • 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
