The Gamo Swarm Magnum 10X GEN3i gives you a faster and easier way to shoot a multi shot breakbarrel compared to the previous version. You get a lighter and lower profile 10X GEN3i quick shot magazine that gets 10 shots before reloading and uses a system that uses the inertia of recoil to load pellets, giving you speeds up to 1650 fps with alloy pellets.

This rifle features an IGT Mach 1 gas piston, so you get the benefits of an inert gas technology powerplant instead of a typical spring piston. That means smoother cocking and shooting with less vibration, better cold weather performance, more longevity, and the ability to leave the rifle cocked for long periods without spring fatigue.

The Swarm Magnum lets you separately adjust the amount of travel for each of the stages of the 2 stage Custom Action Trigger to get the crisp break just right for accurate shots. Also, the rifle gives you the comfort you're looking for with the Shock Wave Absorber recoil pad that cuts down on recoil you experience by up to 74%.

With double chamber integrated Whisper Fusion noise suppression technology, Gamo gives you their highest level of noise reduction for a quieter shot that's less likely to scare away game. The all weather thumbhole stock is glass filled and made with automotive grade nylon, and it has checkering on the forearm and grip, so you get a firm grip even in wet conditions.

The included Gamo 3-9x40 scope with rings is fogproof, waterproof, and shockproof. If you're ready for a smooth shooting multi shot rifle with scope for pesting or small game hunting, get the Gamo Swarm Magnum 10X GEN3i at Airgun Depot.

Nothing to add

I cannot get it to accept the magazine so I can use it, so I can write my review.

By raymondUSAJune 22, 2023 Verified Purchase

Pellet loader, extra magazines, a big plus. After using one all others are a toy.

Lots of power, speaks with authority, it is louder, lighter than a Benjamin. Will need a pellet loader & extra magazines 3 or 4. Looking to add additional ones. 25cal definitely has my attention. .177 & .25 would make pair. 1 for practice and the other for when hard punch needed

It is harder to cock, loading magazine by fingers can be a bit of tricky pellet loader a big plus .

By RonMay 27, 2023 Verified Purchase

With majority of online reviews and reviewers touting this is one of the best break barrels since the dawn of time. For the money I am searching for the positives. I found only one. The auto loading feature. That was all I can find. I would not recommend for an average person. Be sure to keep some money above and beyond to get a descent scope.

Not much. I like the auto loading feature

Was not impressed enough to have positives. Scope sucks. Magnum means difficult to cock. Reportedly quiet NOT Really that quiet. If you do not use the artillery hold DO NOT SHOOT THIS AIR GUN.

By JuanUSAMay 20, 2023 Verified Purchase

Buy it if power is needed

Accurate and precise

Hard to cock

By KevinMay 13, 2023 Verified Purchase

The cocking effort is significant. Pellet weight selection for this rifle is key. Anything below 8-9 gr. tends to break the sound barrier resulting in much higher noise and decreased accuracy. Ideal pellet weight for the .177 rifle seems to be about 10-11 gr. Very pellet picky in my experience if you want reasonable accuracy.

When it shoots, the rifle is quite powerful for a break barrel. The included scope is of decent quality for the price. The synthetic stock seems to be a better quality than some budget priced rifles. When you find a pellet it likes, the gun is reasonably accurate for back yard plinking and small pest control. The whisper sound suppression seems to work well when shooting pellets that do not break the sound barrier.

My rifle already requires warranty service. The magazine loading system does not reliably feed pellets, resulting in the pellets falling out or getting smashed/destroyed. I have tried multiple pellet brands, weights, and shapes to no avail. To their credit, the Gamo customer service people were responsive and are mailing out replacement parts. The scope only mounts in one specific spot on the rail due to a metal detent that fits in the receiver requiring you to adjust your eye placement instead of adjusting the scope distance from your natural shooting position. Replacing the rings/scope mount would remedy this issue.

If you want shoot only few, I think is Ok, for mi if you are a very heavy and strong guy. I'm very sure is nothing wrong with the gun, only, is intend it to use for only determinate people. (need correct that)

I don't have nothing to say about it.

After I have this gun from Air Gun Depot, try to cocking the gun, I found this gun is not for me, because the real hard cocking force, every round. The idea to have this gun is for plinking in the backyard, and, have fun, no torment.

By KennethApril 25, 2023 Verified Purchase

The delivery time was exceptionally fast.

I have all 3 versions of this rifle and each one was better than the previous version. All were great!

By GregApril 10, 2023

I have two of these, one with no scope as it has open sights. But my second one had no open sights and I have to use the scope, which is a good quality scope. But when you are hunting small rodents an open sight is quicker to acquire the target.

This Gun is Accurate! better than a 22 long rifle at 150 yards. I love the ten shot cartridge, just pump and shoot.

You need to be a MAN to pump this gun! which is funny when you hand it to a boy and watch them try to pump it.

By Jesus USAMarch 20, 2023 Verified Purchase

The scope is ok in my opinion and or my use but others may want to get something a bit more features and sharpness.

For a .22 break barrel I love the power it has.

Cocking is pretty heavy but you get used to it. Look at the brightside you get a nice little bit of strength training.

Adam from USA

Hi I live in the UK and I would like to purchase Gamo Swarm Magnum Igt Gen3i Caliber 5.5 but I would like to know if you ship to the UK and how much does it cost to ship here?

asked Marcio from United Kingdom

How do I know if I will receive an upgraded mag if I buy the gun and additional mag today? Where can I buy the upgraded trigger kit?

asked Michael from USA

Does a anyone know why we're still using Dovetail mounts on such a powerful Rifle? With and at this kind of recoil and being a springer type Rifle, you would think the Weaver Rail being a wider base and each segment with a stop would be Gamo's first choice, but I'm definitely not a engineer. Does anyone know?

asked Rudy from USA

Gamo Swarm Magnum 10X GEN 2 .22 can be delivered to Canada

asked JEAN-GUY from Canada

The Info. State's "having ability to leave the rifle cocked for long periods of Time" with out any kind of loss! My Q. Has anyone chked. how "Long of period of time" that actually is ? (1min,5min.20min.45min) ? any input would be much appreciative!

asked Mark S from USA

Left mine cocked for a day or two a couple times and no issues so far

Clayton from USA

Does this come with the magazine or is that a separate purchase?

asked Bradley from USA

Comes with one magazine . Extras can be found at Gamo's website .

Stanley from USA

Is this barrel choked?

asked Logan from USA

Yes it is a choked barrel.

kyle from USA

Is it possible to remove the Whisper Fusion noise suppression either by unscrewing it or otherwise. Thank you for the answer.

asked JEAN-GUY from Canada

What is the max energy of this. In .22 cal

asked Brian from USA

Has anyone shot past 75 Yards? it seems like a powerhouse. I have a Hatsan 125sniper in .22 and .25 on a good day I can hit about 90 yards consistently. I don't hunt I just like the challenge

asked Greg from USA

Can I use quick cleaning pellets in this gun? If yes do you load them in the Gamo Swarm Fusion G2 10X GEN2 Quick-Shot mag .177 like you would a lead pellet?

asked David from USA

Doubtful since you need to load 3 in a regular break barrel to create enough back pressure.

Jason from USA

What is the twist in a rifle barrel?

asked Thomas from USA

Most airguns if rifled are a 1 in 16 twist.

kyle from USA

Are you asking for the angle of the twist? Or why there is one? If the later it spins the pellet making it more accurate. Think throwing a spiral pass with a football. Never put a BB in a break barrel

Jason from USA

Can I use a bipod with this air rifle? If so, which one would recommend?

asked Artillon from St. Vincent and the Grenadines

Side mount bipods are available . Try airgun .

Stanley from USA

Any yall know were exactly this riffle is made?

asked Mark S from USA

barcelona,spain. If your worried about quality,dont be. they feel like real guns. hope that helped.

neme from USA

Spain I thought
