The Umarex Octane has a lot of things going for it: Reaxis gas piston, SilencAIR integral noise dampener and a 3-year warranty. If you like to hunt, then the gas piston and the integral silencer will go a long way toward making your hunting trips more enjoyable and less disturbing if you're shooting it in urban or suburban areas. Plus, the reduced sound also let's you take game or eliminate pests without warning other animals in the area that you also want to dispatch. Leaving your air rifle cocked a bit longer while you wait for your prey to become available won't hurt your gun at all since it has no metal mainspring. Lastly, the 3-year warranty is 3x longer than what most other manufacturers offer. So, if you're concerned about the integrity and the life of a gas spring, know that Umarex is there to support you.

SilencAir Technology is a 5-chamber noise dampener that’s permanently affixed to the muzzle of an air rifle and is intended to reduce down-range muzzle noise. One of the most common questions asked about an air rifle is, “how loud is it.” The technology behind SilencAir is an answer to that question—reducing the decibel reading of the muzzle noise generated by the exiting of a pellet from an air rifle.

Reaxis Gas Piston
Many of today’s modern single-strong pellet rifles use a sturdy spring that’s compressed when the barrel is broken over and released when the trigger is squeezed. Umarex’s new rifle houses what’s called a ReAxis Gas Piston. Think of a gas strut or something that looks similar to the shock on a car. When the barrel is broken over, the gas piston is compressed and locked in place. When the trigger is depressed the piston rushes forward shoving the air that occupies the receiver through the breech hole, behind the pellet, and down the barrel.

Umarex octane and pellet review.
October 10, 2014
When I went to sight in the Octane, I used some cheap 177 pellets that I've had for some time to use them up. At 50 ft, with a gun rest, it sprayed the pellets inside a one foot circle. Hard to believe any pellet could be that inaccurate. I then tried some copper plated H&N field target trophy power ( 8.8gr ) and accuracy greatly improved. I then shot some Gamo Armor piercing PBA pellets ( 6.8gr) and at 30yds they are very accurate. Now to experiment with other pellets.
Very well made. Very accurate. Good scope. Great price.
Rather heavy. Shooting PBA pellets it is as loud as a 22 rimfire. Lead pellets are much quieter. Cooking effort is high but is to expected for the fast FPS.

Great rifle overall - Excellent Deal
September 6, 2014
Ordered the refurbished .177 Octane, and am very happy with it, overall. Rifle has great balance, sleek great stock feel and design, feels lightweight and smaller than advertised (especially without the scope.) Moderator works well-with the right pellets. Gas piston is a plus. about 50 shots thru it so far... Had to tighten down stock and barrel-pivot screws. Have only taken out once so far, but look forward to more shooting soon. Did not bother to mount the included scope. Will use it on something else... I doubt if it will withstand the power of the Octane for long. These springers work best with open sights IMO.
Rifle is powerful, but velocities are quite over-exaggerated by Umarex. It is maybe a bit stronger than most "1000fps" springers. heavier weights were not shooting too flat @ close ranges (~20m). Im glad i got the .177 over the .22 because of this. .177's about 10-12 grain will stay subsonic to keep quiet and accuracy as well. Cannot beat this deal at this price. octane is quite accurate, rather smooth, and fun to shoot. open sights are great so far, and within the proper range of adjustability. very nice look and feel. accurate (tight touching groups with the right pellet) Baracudas worked well, didnt seem too fussy re: pellet choice.
Trigger needs a little work. There are lots of tutorials on how to improve the trigger. i will try the adjustment-screw-smoothing mod first, then, if needed, polish the trigger surfaces. It is not too bad, but some pretty rough spots, but it should be fine with minimal-moderate attention.. Trigger feels a bit heavy and rough. just needs a small adjust or might break in over time...

Very good and powerful rifle. Scope is good too. I use 7.56gr "Gamo Hunter" pellets, I think It's normal for plinking and hunting birds about 25-30 yards.
Heavy weight.

Love It!
August 27, 2014
This is my 4th air rifle in a week. I returned the other 3 as I was not happy with them. The gas piston is awesome it is quiet and smooth. So far It is dead on at 20yrds not getting consistent groups at 40yds yet but I will have to experiment with other pellets I expect to have this rifle punching bullseyes at 50yds. The rifle takes a lot of energy to cock but that isn't a problem also it is quite heavy but since I will mainly target shoot with it that is of no concern.
Excellent scope and mounts for an airgun.The stock is great..177 cal.
No place to attach sling.

Overall - Very Good Value.
August 26, 2014
Overall I’m very pleased with purchasing a refurbished Octane .177 Opened the box – and all was in order – nothing missing. You should clean the barrel as mine was very oily and dirty. Once the cleaning patches came out clean I sent 50 or so pellets down the barrel to do a slight break in. Mounted the scope – and with-in twenty or so shots – it was shooting half dollar sized groupings at 25 yards. I have not tried any longer shots. Heavy pellets work best I think. Crossman Premier – domed – 10.5 grams is what I used.
Price, Accuracy, Scope. The scope is very impressive and seems to be very well built.
On the negative side: the trigger gave out after 200 shots or so. As I live in the UK (Having purchased the gun while on vacation in the States) sending it back was not an option. So I took the gun apart to get at the trigger assembly. A pin had fell out - but not lost thankfully. Using a picture of the trigger assemble found here: - and putting a piece of duct tape on one side of the plate (piercing all the pins through the tape to hold them in place) all is well. My barn pigeons are on the decline and squirrels are in a stew.

The gun has been great and was like new. The scope was way off but easily brought on target. Great shooting gun powerful and smooth.
Strong shooter
The safety needs to work the other way. I know that going in from other reviews I had seen.

After reviewing and researching different makes and models, I chose the umarex octane .177. I hit it right on the head, this gun is great !!!!! Been a hunter and shooter all my life, out of the box 15yds open sights 3-4 for adjustments, bam 1/4" groups all day long. Put scope on gun,( love the rail mount and weaver style rings) another 8-10 shots had it zeroed in at 15yds. First shot on garden pest apprx 18yds, let's just say Alvin no longer heads the band, second at 30yds and Theodore joined his brother. Gun is great. As for my responses to some of the cons that I have read, noise is not as loud as some would suggest, gun has a little recoil, will have to wait and see how the scope holds up, right now the scope is excellent for this gun, have apprx 100 rds through the gun and still holding zero. If you are looking for a high quality rifle at good price the Umarex Octane is for you, and buying refurbished will save you even more $$$ and the gun looks new and shoots great, no issues with mine so far. Buying from Airgun Depot has been a pleasure.
Power, accuracy and price,
Haven't found any yet, if I do I will post immediately.

Refurbished Umarex Octane Air Rifle- .177 Cal
July 24, 2014
This is my first pellet rifle after reviewing all the info. I could find comparing some what like models. It seems this Umarex Octane was scored higher in quality and power, accuracy then a lot of the others. When I received it I was impressed whit the quality and features it came with and the accuracy of the rifle after taking time to zero it properly. I was happy I bought this rifle. It was shipped out from Air gun depot the next day, but the shipping carrier Fed-ex smart post was very slow.
Material used and quility of workman ship. accuracy and power of rifle.
weight, it has a little weight to it, not a child's gun

Powerful Gun
July 24, 2014
This is a great bargain on a powerful gun. You cannot tell this is a refurb as it is like new. The scope is excellent! Far better than you would expect for a combo deal.
Well made! Powerful! Great optics! Accurate right out of the box, Can't wait to see how it improves with time. Women and children won't be cocking this gun as it required signifiocant effort. Not a con just a fact. I thought with the supressor I could use it for pests in the city. It is very loud but to be expected with a gun that has this much power.
noise and cocking effort but no deal breakers

great gun
February 16, 2014
I'm still sighting it in, but right now I'm hitting bottle tops from about 25-30 yards. I'm using Gamo hunter lead pellets, not to loud, but the Raptor power pellets are significantly louder! both are to loud for my suburban neighborhood. the only way I can shoot without disturbing my next door neighbor is by shooting across my bedroom through my doorway and across the yard. I've placed a sheet of two inch thick insulation foam in the doorway and cut out a 3.5" - 4" hole I shoot through. It works well.
seems well made for being made in China. smooth break barrel action. the weight helps with the kick. I also like the scope that came with it.
nothing so far other.

Hits the Nail on the Head!!
February 15, 2014
I bought this gun for a good price here at Airgun Depot and it is some kind of accurate. I can hit a 16 penny nail head at 25 yds and a 2 in circle at 50 yds every shot no problem. This gun is very balanced and it is very quite for the velocity that it is shooting. The scope is extremely clear and crisp with very fine tune adjustments. The trigger was terrible when I got it but I found a little screw that need to be tighten and now it is just perfect. Airgun Depot has terrific service and wonderful products. If you want to buy an air-gun for cheap and something worth paying for buy it here at Airgun Depot. Thanks a lot Airgun Depot!!!!!
Incredible Scope Very Balanced Quite Shooting Nice Trigger Adjustments
Not one thing is wrong with this great airgun.

Just as advertised.
November 13, 2013
If you are looking for some backyard target fun or even small game hunting, the Umarex Octane .177 is the ticket. Out of the box as well as 500 pellets later, the power and accuracy is consistent. We are talking groups within 1" at 30 yards with Crosman Destroyer pellets. The noise level with standard pellets is certainly tolerable for In-town back yard use. However, using the high velocity alloy pellets where super sonic FPS levels are obtained, breaking the proverbial sound barrier may be too loud for most inner City back yards. Overall satisfaction Is such that I have already recommended this very rifle to my brother and many friends.

Wow, Don't Forget the Ear Protection
November 12, 2013
This rifle delivers a fast and accurate shot. The trigger has a light pull. The rifle sites well. The pellet velocity is very high, and went through my targets and backstop like a bullet. I had not used a gas-piston before and was surprised at the noise at firing and the smell after the first shot. It felt and sounded like I had fired off a shell. My ears rang for about 5 minutes. Don't forget the hearing protection. Oh yes, and read the instructions.

Excellent Air Rifle
October 19, 2013
Purchased the rifle, received excellent service from Airgun Depot. The gun shoots with plenty of power and is very accurate. I bought it in 22 cal and find it will do the job on small game, I feel the rifle is mainly suited for hunting, due to the fact that it is quiet, and that it is very hard to pump. You would not want to pump this one just for plinking.
Plenty of power. Quiet and very accurate. Inexpensive. Pellets are relatively cheap. Well made and very sturdy. Made in Japan.
Would like a softer butt plate, not for recoil but when cocking. Takes a lot of power to cock.
