Umarex Octane Review 2021: Is it for YOU?

Uncategorized

No one wants to be ripped off.

And everyone’s afraid of trying new things because of this.

Understanding customers’ thinking, many air gun manufacturers offer up to a 1-year warranty for their rifles.

Umarex is one of the few manufacturers that offer a 3 year limited warranty.

giphy Umarex Octane Review

I can confidently say that I have confidence in their products.

The Umarex Octane rifle has more than just the warranty I expected.

In the next 5 minutes, I’m sure you will nod your head and say, “I see what you mean” after reading this detailed review.

Umarex Octane – Guntype

This is a gun with a gas-piston cartridge

(For more information about the 5 types air rifles you must know before buying, please see this post.

It is powered using ReAxis' gas piston technology.

Surprisingly Umarex is actually the first major air gun manufacturer to reverse the direction of the gas-ram.

You will be more powerful and reliable if you do this, they claim.

We will see if it works at the end of the review, but first let's look at how the ReAxis Gas piston operates.

ReAxis simply stands for Reverse Axis.

Umarex claims that the ReAxis piston works in reverse, and is not like the nitrogen-filled gas piston.

This means that the gas rod is pushed against the piston by the larger gas strut.

This means it produces more power, velocity, impact, and force than other gas pistons.

t1 Umarex Octane Review

Now we know what a ReAxis gas ram is, let’s take a look at its benefits over a spring-piston.

First, you have smoother cocking since it doesn’t have spring torque like metal springs.

Second, there is no spring fatigue even if you leave it cocked for hours so you don’t have to worry about the piston wearing out over time.

The weather does not affect the ReAxis gas piston.

The mainspring is greased with oil to make it more difficult and harder when it gets cold.

ReAxis strut doesn’t have this problem and it functions perfectly in different types of weather.

Fourth, the ReAxis Gas Ram allows for smoother shooting and lower recoil when compared to spring-piston.

It lasts longer than any metal spring.

It is not unusual for spring compression to exceed its normal threshold in the world of air guns.

This reduces the life span of springs and weakens their performance.

However, the ReAxis gas piston doesn’t care about compression so you can enjoy long-time shooting with it.

The caliber is available in both .177” (4.5 millimeters) and.22” (5.5 millimeters).

The preferred choice for hunters is.22 caliber.

While the .177 caliber offers more velocity, it usually doesn’t generate enough takedown power to kill an animal in 1 quick, clean shot.

On the other hand, .22 caliber has more knockdown power transferred to the target’s body so it’s the go-to gun for field hunters and pest eliminators.

The Umarex Octane single-shot, break barrel gun is the Umarex Octane.

Break barrel design allows for unlimited capacity

You don’t have to worry about shooting capacity when your air gun runs out of power such as CO2 or PCP air guns.

Besides, single-shot action gives you control over the ammunition you’re going to shoot.

In a matter of minutes, you can find the best pellet for your gun.

In addition, a single-shot rifle hones your marksmanship skills:

Because you only have one shot at hitting the target, aim and shoot carefully before you reload.

(For more information on the top break air rifles available, please see this post.

This rifled-steel barrel air rifle is made.

This post will provide more information about air rifle barrels and how to use them before you buy.

Umarex Octane includes a noise-dampener called SilencAir.

It has five chambers which reduce muzzle noise.

SilencAir is specifically engineered for air guns.

The first pellet that enters SilencAir pushes air into an airport chamber called the anterior tube.

The pellet then pushes air through the ring, through the airport, and out of the second Chamber.

After this, air is forced from the third, fourth and fifth chambers. This lowers the audible signal at the muzzle.

Umarex Octane is a stealthy and secretive hunting drug.

Stock

r1 1 Umarex Octane Review

Umarex Octane 22 air gun features an all-weather synthetic stock.

It’s very suitable for people who live in cold or humid places and for shooters who don’t want to bother with stock preservation.

(For more details on the in-depth comparision between synthetic and wooden stock, please see this post.

Stock is ambidextrous

It offers the same shooting experience for left-handed and right-handed shooters.

It doesn't matter if you are right-handed or left-handed.

You will also notice the nice texture on the forearm, grooves on your grip, and the ability to stop sweat from slipping. This will help you avoid slippage, improve stability, and improve accuracy.

The stock also has a rubber buffer to absorb recoil. Even the ReAxis gas piston reduces recoil by a lot.

Last but not the least, the thumbhole design of the stock allows you to have a more relaxed grip on it by resting it on your wrist rather than with your arm.

A thumbhole stock works best for varmint shotpers and anyone who spends a lot time in shooting positions such as bench rest shooting.

Ammo

Umarex Octane uses both.177 and 0.22 pellets, which correspond to the 2 types of calibers.

You can find hundreds of high quality.177 pellets for just a few dollars.

For plinking and target shooting,.177 is the best option.

A.22 pellet, on the other hand is heavier and has greater knock-down power that a.177 pellet. It is therefore the preferred pellet for small game hunters and pest eliminators.

(For more on the differences between .177 & .22 and which jobs they do best, see this post.)

Cocking and loading

The gun is cocked:

Put the gun “ON SAFE”, hold the rear stock firmly without contacting with the trigger,

Hold the gun close to you and grab the barrel from the front sight.

Pull downward to its limit until it stops and don’t let go of the barrel

Loading the gun

With the breech exposed when you cock the air rifle, insert the pellet into the chamber (with the pellet’s nose lying forward).

Now, you can fire the gun by bringing the barrel back to its original position.

Sight

Umarex Octane has a beautiful open view that I love.

Fiber optic is the front sight, which means it uses optical fiber to place the dots.

The rear sight also has fiber optic.

It’s fully adjustable for windage (allow you to adjust the sight left and right) and for elevation (allow you to adjust up and down).

(For more information on the different types of air gun sights and which one is best for you, please see this post.

As if the full fiber-optic sight is not enough for dead-on accuracy, Umarex adds a 3-9×40 AO scope in the package.

40 is the diameter, in millimeters, of the front lens.

3, 9 and 10 mean that the scope is capable of variable zoom-in power.

It magnifies an image by 3 to 9 times more than the one you see without it.

This scope also features parallax adjustment.

Adjustable objective is a way to adjust the sight according your needs.

The Picatinny rail comes with an integral dovetail and is included in the same air gun.

This rifle is equipped with that feature.

You can either mount whatever scope you want on the Picatinny or take out the Picatinny and use the 11mm Dovetail.

Velocity, power, accuracy and speed

r2 1 Umarex Octane Review

The Umarex Octane is a.177 caliber and delivers speed up to 1450 FPS when using an alloy pellet or 1250 FPS when using a lead pellet.

This rifle can produce 1250 FPS when using alloy pellets and 1050 FPS when using lead pellets.

These velocities have put Umarex Octane within the ultra-magnum range of air rifles.

You can also hear the crackling sound of the pellet breaking sound barriers because it travels at 1100 FPS.

Loudness

Umarex Octane is a supersonic gun that can fire in.177 or.22 calibers. However, it produces very little noise due to its advanced noise suppression technology.

So you can enjoy a successful hunting or fun plinking day without disturbing your neighbors.

Shooting Ability

This gun can shoot up to 100 yards. It can be used for small game hunting, target shooting, plinking and pest control.

Pros and cons

t3 Umarex Octane Review

Prices

Umarex Octane costs just 200 dollars.

It’s a bargain if you consider the innovative ReAxis gas piston, advanced silencer that makes a supersonic sound no more a problem, heavy-duty power, eye-opening velocity, and extreme shooting range that every shooter dreams of.

There are many listings online, with different prices, but the one I found with the lowest cost is the best price from online e-commercial sites such as Amazon, PyramydAir and Walmart.

Customer review

Many customers have left glowing reviews about the Umarex Octane.

It has received positive reviews. People love it for its power, accuracy, speed, silencer, gas piston and state-of the-art technology.

Negative reviews indicate 2 main problems

The first is that the gun is too heavy for them to handle so it’s not for skinny shooters.

Its solid size allows you to control your movement on the bench rest shooting.

The second problem is the noise: they said it’s too loud but the gun will quiet down a lot after the break-in period.

Conclusion

Although I love the Octane, I do have some words of caution:

This is not an easy way to learn.

If you are a fan of magnum power, and believe you can control the beast, then go for it!
