Umarex Octane Air Rifle Combo, Gas Piston
Here are the benefits of the Umarex ReAxis gas-piston:
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 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: Everything.
What others should know: The below review, that was submitted before this addendum, is from Woodys World. I do recommend this air rifle in either caliber. Get a chronograph. Woodys World.
Things I liked: Power, price, size, and everything about it. This .177 arrived yesterday, 6/20/2018. I also have the .22 version, which I bought two and a half years ago. Shooting this one, I am already acclimated, just a different caliber. I did not opt for the Stop-Shox version, even though I thought about it. I was sold on this version, if it aint broke, it doesnt need fixing. The scope is good, I know eventually the shock may cause a need to upgrade. I already have two CenterPoints. I will change when that time come. It took me 8 shots with the Crosman Ultra Magnum 10.5 grains to zero the scope on the 2 inch target at 80 feet.
Things I would have changed: Nothing.
What others should know: The only modification to this is the breech seal and two shims. My opinion, all reviews should be conducted on all air rifles as they were purchased, shipped, and received, as is. After mounting the scope yesterday, I did take about 15 test shots, after cleaning the barrel, from 3 different pellets: the 10.5 grain Crosman Ultra Magnum, the 9.26 grain H&N Crow Magnum HP, and the 11.57 grain Beeman/H&N Sport Silver Arrow. I chronographed 5 shots from each. The 10.5 grn.Crosman Ultra Magnum results were: 918, 938, 929, 930, 926 fps, averaging 928 fps. The 9.26 grn H&N Crow Magnum: 1040, 1046, 1028, 1048, 1024 fps, averaging 1037 fps. The 11.57 grn Beeman/H&N Silver Arrow: 880, 887, 868, 877, 878 fps, averaging 878 fps. For accuracy, 5 shots each at a 2 inch target at 80 feet, in 79 degree weather. The Ultra Magnum and the Crow Magnum both put 3 hits in the 1 inch inner circle with the other two hitting the 2 inch target. Silver Arrow 5 shots hit together, less than a quarter inch below.
Things I liked: Love the gun
Things I would have changed: too hard to cock
What others should know: no

Is the front sight easy to break and is there a cover you can get to cover it ? Thank you
Yes, it is easy to break, be careful. I have owned .22 caliber Octane for 3 1/2 Years, broke mine in the 1st 6 months. The rifle fell over ono the floor. You can buy replacements, I never bothered because I never shot it without using the scope. No, there is no cover for it.
Help! I have a RWS 48 .177 with X6 scope, shooting 10.6 Piranhas. Out to 50 yards is a pass through on small game, I want to increase grains to 11 - 14, but afraid of blowing gasket, can anyone recommend a heavy pellet that acceptable for my rifle? Thanks
My personal advice, for accuracy shoot 10.00 grain and heavier pellets. Do not shoot super light weight PBA pellets, you will be asking for trouble or maybe piston problems. Do not Dry Fire without a pellet in the breech or shoot only felt cleaning pellets. Get a chronograph. Woodys World.
You will not blow gasket using 11-14 grain pellets. Never shoot your rifle with no load/pellets in the breech. The lighter the load/pellet or intentional deiseling could result in that type of damage.
Any pellet 10.5 grains and heavier will do. You have to be able to tame the recoil and weight of this beast. It wont be the rifle, it will be you. The Crosman 4.00 grain and Gamo Air Star 4.20 grain will exceed that 1450 fps depending on the weather temperature. Buy a chronograph, then you will know.
If it really does 1450 fps then a heavier pellet will help tame it some . Rifles with that much power like heavier pellets . JSB makes some really good heavy pellets for magnum airguns.
Is this air rifle more accurate than the gamo hornet maxxim .22 or should i go with the gamo hornet maxxim.22 instead? By the way i will be shooting squirrels out to about 25 yards
The only person that could answer that are those that have the Umarex Octane .22 and Gamo Hornet Maxxim .22 cal., otherwise they would be speculating. I have the Umarex Octane .22 and the Ruger Air Magnum .22, I CAN tell you, without speculation, how they compare. Why not get both of them, they are different, plus you would have two good magnum powered air rifles in your air gun arsenal. I shoot my Octane and Ruger Air Magnum equally. I have complete confidence in both of them when shooting at a 30 yard target. They both blast 14.30 grain Premiers clean thru squirrels at 30+ yards. GET A CHRONOGRAPH. Woodys World.
A squirrel is toast at 40 yards, one shot kills with the Octane and Crosman 14.30 grain dome or destroyer pellets.
A squirrel is toast at 25 yards with an Octane. I've shot right through one with 15.3 grain Exacts.One shot kills. Head shots preferred.
