The Umarex Octane has a ReAxis gas-piston- SilencAIR integral silencer and a 3-year warranty. If you like to hunt- then the gas-piston will go a long way toward making your hunting trips more enjoyable. 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. If you're concerned about the integrity and the life of a gas spring- know that Umarex is there to support you.

Good hunting rifle.
July 1, 2016
I bought this rifle as a refurbished item and I couldn't be more pleased. Not only did AGD knock of a few bucks but the scope was already mounted, so there was nothing left to do after unpacking but shoot. This rifle is very well made - I will continue to purchase Umarex products, as this was my first. The gas spring is very smooth and the power is awesome! I tried four different pellets and was getting over 20 fpe. The best fpe at 22.225 and also producing the best groups were from RWS Superdomes averaging 1098 fps. The best noise reduction comes from using heavier pellets and getting below the sound barrier. With the CP heavies it becomes one of my quietest guns. Oh yeah. The scope supplied was quite surprising. This is the first time I don't feel like I have to replace the scope that came with the rifle.
Good power for taking small game. Also, quieter in the field with the heavier pellets.
Not for plinking unless you are Superman.

Can't beat it it for the money
August 1, 2015
I used a laser bore sighter and dialed it in right out of the box .Took it outside shot 5 crosman premier thru it had 3 rounds touching and the other 2 less than a 1/4 " from the 3. Switched to some Gamo alloy and fine tuned it. Rifle shoots great. Scope is not bad,but I'm going to switch it with a stronger mil dot scope. Trigger is surprisingly good. It could use a little work. Definitely an adult air rifle mainly because cocking it is a beast. Very accurate. Actually it's probably the most accurate rifle under $500 I've ever shot. I own 2 Anschutz rifles and a Feinwerkbau. So I know the difference between high end rifles and the Octane performs as close as you can get without spending a lot of money. That's why I bought one. Also read many reviews and never read a bad one.something I always do before purchasing a new rifle or pistol.
Price definately can't be beat. Overall great performance. Good scope. Decent trigger
Cockiing is a bit stout. My 12 year old grandson had trouble with it. Trigger not bad but can be improved with a little work. The safety I don't like. It's backwards. Otherwise it's one of the best rifles out of a box I've ever had the pleasure to shoot.

Reserach led me to Umerex Airgun depot
July 18, 2015
After spending mos. researching affordable air rifles to take small game with . The Umerex Octane kept popping up . This is a fairly new gun ,but the recoil seems like a 22 cal without the noise. The 1200 fps velocity has good punch with pb pellets. The scope is fair for this level of gun . No problem hitting squirrels and chips at 20 yrds. after its sighted in. Refurbished is the way to go apx. half price of new.Of coarse Airgun Depot had the best price . And after 3 weeks the gun went on Lightining Sale the credited me the difference. The gun is a bit heavy but it adds to the stable feel of this it . Very pleased with this purchase .
Accuracy at this price level Airgun Depot for customer satisfaction

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.

Overall - Very Good Value.
August 26, 2014
Overall Im 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.

No disappointments
August 25, 2014
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,

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
