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 1300 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.

The gamo mag 10 is fare priced, the scope in the package is poor quality.

By DaimonJanuary 1, 2023 Verified Purchase

If you have lost the edge and love for shooting, this will be the air rifle that makes you fall in love with shooting all over again!

If I had a "dream" air rifle to add to my collection, this Gamo Swarm Magnum 10X is that rifle. And it seems that my time of waiting worked out with regards to owning the "GEN3i. What an amazing machine. Plenty of power and very accurate. The length, weight, feel and balance are in a class of superior competition air rifles. Gamo gave us a "masterpiece in the Swarm Magnum 10X GEN3i, And I look forward to many wonderful experiences shooting this gun.

Nothing so far!

This is the second Gamo Swarm Magnum I have purchased from Airgun Depot. First is a Gen1. Sighted in at 20 yards then switched to the the silhouette targets.

By CooperUSADecember 26, 2022

Basically a Barrett in the air gun world but when breaking the sound barrier with good pellets its like a 22 Lr.

Great scope, very very high power breaks sound barrier first shot overall quiet when going sub sonic.

Grip tape can scratch you up if you don't be careful about how you hold the rifle. And ways a lot for a pellet gun.

By DouglasUSASeptember 5, 2022 Verified Purchase

First - the service here is excellent. My third Gamo rifle, very powerful, 1 inch group right out of the box.

Magazine will not work with all shape pellets. Short skirt pellets fall out when cocking.

By MichaelUSASeptember 4, 2022 Verified Purchase

The magazine is nice your not dropping pellets everywhere and have not had any problems with cocking. The first time was a bit more then expected but after you get a comfortable position to break it you really do not feel the extra 11 lbs of pull.

I really like gamo air rifles this is my second one in .22 cal. The velocity is awesome.

The scope should had been upgraded to 100 yards.

By DouglasUSAAugust 18, 2021 Verified Purchase

Don't try to get away with cheap pellets that have no QC when made. Buy the good stuff and save a lot of time and money.

Overall nice. This will be one year I have owned this rifle. Last fall it was used for squirrel season. You must find the right pellet for the rifle. Like my .22 rimfires, only one type of ammo works. The same with this Gamo, find the pellet that works, than learn about it at the range. This fall I will be out with my Gamo for squirrels.


By TimothyUSAAugust 16, 2021

I have the first generation of this in .22, and it is very close to the favorite rifle in my stable. It hits hard, is accurate, and is also surprisingly friendly to cock and relaxing to shoot an extended session with on the range. Because Gamo kept the weight down, it is also good in the woods, as it is relatively light for something with this quantity of smack. Smack it has. Great whomping beat-down power. Throw a heavy pellet in it, and it will trash your metal targets. For all that, it's quiet, or at least as quiet as you can make artillery. It's long. If you care for a carbine, you won't find it to your taste. I put the $9.95 search it on the internet trigger screw kit in, and spent an afternoon dialing it in. The trigger went from pretty good to outstanding. I have a short plateau followed by a clear wall, with a nice break at under two pounds. For the price on these, you cannot go far wrong. I haven't shot one in .177, but I hope to soon.

My go-to break barrel. They checked all the boxes. Very nice mag system.

Very little. A Picatinny rail as standard would be nice.

By MarkUSAJuly 26, 2021 Verified Purchase

Changing the loading mechanism and magazine were really not necessary since the one i removed was okay. The new magazine Gamo sent in .177 had the word "updated" on the package but I could not see any difference unless the o ring and spring tension have been modified to better hold the pellets and stop the next pellet from jumping up following the recoil of the preceding shot. Be aware that the high 1200 plus fps ability of this rifle will break the sound barrier and cause a loud crack sound and loss of pellet accuracy. Recommend using above 8gr or heavier pellets in .177 to prevent this.

High velocity, comfortable stock, overall quality for price

Magazine and loading mechanism require more work by Gamo or at least better information on loading technique specifically: 1. Caution on inserting pellets in magazine because an o ring is used to hold the pellet in place and certain pellet skirts are held better than others. Pellets will fall out of magazine if pushed in too far. Pellets will raise up in magazine after firing on occasion so prior to breaking the barrel you must ensure next pellet has not jumped from proper seated position. The is a technique required to break the barrel to stop pellets from falling out. I place the end of the stock on my left leg with the rifle at about 45 to 60 degree angle then as I am closing the barrel I start to lower the barrel to nearly level. This method stops the pellet from falling out of the magazine which might happen if you kept the barrel tilted up throughout the process. The problem with the pellets falling out is known by Gamo, I changed the loading mechanism and a new magazine.

By PaulUSAMay 29, 2021

This is an adult level weapon, not suitable for pre-teens. needs swivel mounts and shoulder strap to relieve the weight issue (at ready-position).

Looks; it looks very nice; like the magazine clip feature

Heavy; Difficult to charge the weapon by pre-teens. Muzzle tip is too close to the shooters head when trying to cycle the barrel with the butt on the ground to stabilize the weapon; Scope is difficult to sight in, way off on initial attempts to zero weapon.

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
