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.

FANTASTIC first air rifle- you get as much power as you'd get with most other PCP air rifles in any price category (if not more) and one pump saves time in case you need a second shot, especially with self loading clips. I bought it for squirrels until I could get a PCP, this this is so powerful and accurate, I'll keep using it and just get a proper scope. If you're not hitting the target, fix or replace your scope, the gun itself is fantastic. Once zero'd in, if I put it against something stable, I NEVER miss a squirrel, even the small chipmunks. THIS is the one to start with. You will probably not need anything more. I shoot it nearly every day it's not raining (because squirrels don't usually come out when it's raining) and I don't even think about PCP's anymore.

Powerful AND accurate. Junk scope, but each time I reset it, it was accurate and fun. Eventually I added a $29 laser to the now broken scope, back to being fun again. If you take the time to zero in whatever scope/laser you're using (or just get a great scope) this is a great model air rifle. Pumps hard, but worth it to have rimfire power with one quick pump.

Loud, and the scope is junk. Scope worked great for a while, then went bad. STILL GAVE THIS 5 STARS. VERY SATISFIED with the rifle.

By JesseUSAJune 2, 2024 Verified Purchase

Excellent... except... Scope is such garbage it will make you think the gun isn't accurate. Replaced with a Hawke Vantage IR 3-9x40 AO. Perfect exchange no mods or ring change needed. FAR more consistent groupings. Replaced with longer rear trigger screw for near hair trigger performance. These two mods are a game changer and necessary in my opinion. You'll love the gun this way.

Scope and rear trigger adjustment screw

By BryanMay 29, 2024

Awesome all around

Prob the most powerful and accurate gun I have..keeps up with a 22 magnum..

Louder than I expected

By MikeMarch 1, 2024 Verified Purchase

I wish it wasn't a break barrel ! So it would be more accurate

Love the whole gun

Hard cocking

By Luis B Mas MunizFebruary 12, 2024 Verified Purchase

Very powerful and very usable with the gen3i 10x magazine

By DavidJanuary 13, 2024 Verified Purchase

Used it today in the very rainy woods so hardly a control environment. The rifle held up and worked flawlessly. The cocking is yes stout, but totally doable. The scope is kind of Meh, but sighted in well and worked fairly well in the rainy conditions The inertia loading magazine worked well. I was shooting 18.1 grain pellets at about 35 yard and got reasonable groups off hand. They would likely be much better at a range using a rest. All in all a fun rifle to shoot in the field and should make for a good hunting rifle.

Seems well made, accurate and powerful

adjustable comb

By ChrisUSADecember 4, 2023 Verified Purchase

Chose this swarm after viewing very favorable ytube vids. Vids show fairly effortless cocking and talking in normal tones of voice before and after whisper quite shots. I'm dumbfounded as to how we're miles apart!!!

Seems powerful.

Loud as (if not louder than) my son's Henry AR7. Heavy and extremely hard to cock. Inaccurate at approx. 40yds. out. Groupings sporadic at best

By Albert October 29, 2023 Verified Purchase

Awesome rifle, good power


By Rick Brown June 28, 2023 Verified Purchase

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 .

No, as it exceeds the energy limit.

Adam from USA

Iam a renowned shooter from India. Is GST exempted for renowned shooter?

asked M Tiatemjen from India

Not to our knowledge.

Adam from USA

In the .22 cal, can you use rocket pellets in the mag?

asked David from USA

Yes. Absolutely and the rifle just loves the rocket pallets.

Javier from USA

Is this smoothbore so I can shoot darts out of it?

asked Jim from USA

This rifle has a rifled barrel.

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
