    Umarex Octane Overview

    ReAxis Gas Piston System

    SilencAir Silencing System

    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:This is a powerful accurate airgun for a great price. The open site is a nice feature and works well.
    Things I would have changed:It would be nice of it was a little lighter. Scope is adequate but mildot scope would have been nicer.
    What others should know:Change the o-ring as it gets flattened by the warning card (#9 o-ring at your local hardware store). Also be sure to loktite the screws as they were not all done by the factory.

    Things I liked:Heavy, sure feel; xlnt shooter, no qualifications there; EXTREMELY Hard Hitting for a .177"-Caliber rifle, even harder hitting than my Air Arms 510S FAC Superlite custom made English rifle, which does 1168FPS average over 10 shots through the Pyramyd Air Service Dept's chronograph, after break-in it's also more than 1200FPS on my club's certified (CHP and POA approved) chronograph with Crosman Premiere 10.5gr 177"-pellets, from the 1250-count Big Box...which this gun loves to death! A bit hard to cock, but then the power it has demands some strength anyway. Thee reverse-design gas piston driver succeeds in its objectives of calming down the recoil of shots; the piston is stronger than any of my Crosman rifles other than my two Marauders, a 22-Cal pistol, and a .25"-Caliber rifle which are PCP anyway, so they really don't count. Trigger is GREAT, and all the complainers heed to re-think what they wrote. I adjusted mine 1/2 clockwise turn on the adjustment tool=pull now = 2.5-lbs.
    Things I would have changed:Some how improve the stock quality, it's simply too austere for such a high quality rifle; I mean you look at it, and think this: "Man, that looks cheapo!" Really now Umarex, we know you spent a ton of R&D on this rifle, but paalllleeeezzzee give us a stock that looks better than this one does! I also have a Benjamin .177"-Cal signature NPS direct from Crosman factory outlet, and that rifle also has a synthetic stock, but looks 10X more professional than the Umarex Octane's stock. No.2; make the stock Picatinny rail easier to REMOVE!! It took me a careful 20 minutes to finally drive it off the Umarex rails with a padded large shot-peened wedge, and my best carpenter's hammer. Some of us want to run better optics than the OEM mount provides for, you understand? I mounted a BSA Huntsman 30mm RBG laser DOT scope on BKL Dovetail to Weaver 1" forged alloy riser mounts, and the gun loves it! In 20 mins, WITHOUT cleaning the barrel a stitch, I installed the BSA scope, sighted it-ready!
    What others should know:Don't believe the "trigger haters" here, it's a fantastic rifle all-steel trigger assembly, easily adjustable to your liking! Be prepared for the air gun "shock of your life" first time you shoot the thing, it hits SOOOOO HARD it's almost scary, Hah! I used a Gamo pellet trap target, the one with the heavy steel back plate/rear door (replaceable), and after 10 shots the Octane almost put holes in the plate to where I had to replace it before continuing! Sights work great, you don't have to replace or add anything sight-wise, just use the standard Fiber Optic Sights and be happy. For the $$$, this if THE ONE TO BUY! Shoots so dang hard, if you use alloy pellets you're NUTZ! The scope is OK, but forgettable...need a scope? Try my favorite "Hawke Eclipse 30" 4 x 24 x 50mm job, and get shocked again! Great value; the BEST shooter with gas piston that exists today; buy it, don't think twice just do it!

    • Brunon from USA asked:

      Is the silencer legal in Massachusetts ?

      • Val from USA:

        This "silencer" is an integral part of the rifle and cannot be removed from it. As such it's not considered a silencer by ATF.

    • Frank A from USA asked:

      Many reviewers have mentioned they had to buy a new O-ring for the breech. Mine was alright, but can anyone tell me what size O-ring it is? Just in case I end up needing one.

      • Ray from USA:

        My breech seal was flattened to , Evan with this issue this gun hits harder than my diana 460 , this rifle has a ton of power and very accurate rate out of the box .the two don't usually go hand in hand !

      • jose from USA:

        Is the same breech seal that the ruger air hawk and the blackhawk air rifle use.

    • Phillip from USA asked:

      What lubricant is recommended for the reaxis and the breech seal?

      • Scott from USA:

        Umarex recommends "RWS air chamber lube" for the reaxis piston and the breech seal.
