Description

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.

Everything.

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.

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.

Nothing.

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.

Love the gun

too hard to cock

no

John May 25, 2018

That too hard to cock, after you break the barrel, is a testament to its power. Its a beast, big, heavy, and powerful, just like its cousin, the Ruger Air Magnum. I have both of them. I call my Umarex Octane .22 caliber, Godzilla. I call my Ruger Air Magnum .22 caliber, King Kong. My Umarex Octane is the non-Stop Shox. No stop-shox needed for me, I love it like it is. I have tamed the recoil of both. Take your time, do not hurry the shot. Think about what you see thru the scope, then calm down, hold your breath, and gently pull the trigger without blinking. I prefer 14.3 Premiers, any one of them. Also pellets no heavier than 17.0 grain. And, oh yeah, get a Chronograph. Woodys World.
