Gamo has done an overhaul on their repeating breakbarrel and it's better than ever! The redesigned, horizontal magazine orientation, Gamo achieves a rapid-reload break-barrel design without the prominent hump that housed the magazine in the previous version. By employing a system of springs and levers, the mag flips up as the breech is open to load the next pellet, then lays back down in its lower-profile, horizontal resting place until cycled again. Add this revolutionary new reloading system to the Swarm's already lengthy list of features, and you've got an ideal, budget-friendly airgun that shoots at velocities at the very top level of breakbarrel abilities, Gamo contends, reporting .177-caliber muzzle velocities of up to 1300 FPS. Plus, with its Whisper Fusion sound-dampening system keeping the gun's report to a minimum, the Gamo Swarm Fusion 10X Gen 3i is also a backyard-friendly shooter.

This rifle is amazing. If you want something that you can play with or do serious hunting with this is the rifle for you. It’s easy to load and then it’s fast follow up shots. It likes pellets and heavy. Mine shoots well with H&M 10.3 grains that is give me Size groups at 20 yards it took close to 500 shots to get it all dialed in. If it first year you can’t get any type of accuracy go through check all your screws and make sure they’re tight then if you still can’t get good groups after a bit. Change your scope and try for a new scope. I guarantee it’s probably not the rifle .

Very well-built rifle shoots great it’s quiet. It’ll take out small game environments. It’s easy to talk well built stock. The thumb hole is great. The trigger is amazing.

I would like to see a extra clip and possibly a sling

By ShannonAugust 5, 2023 Verified Purchase

Either improve the scope or get rid of it, price should be adjusted accordingly

Quiet, fairly accurate

Scope is junk, repeater does not work reliably, takes a couple of hundred rounds to settle in and pattern

By BillMarch 21, 2023 Verified Purchase

I really wanted to like this rifle, and as I stated, it has some nice features that I liked. However, the bottom line is what good is it if it won't shoot accurately and consistently. I am not a novice, and I am shooting off a rest at 25 to 35 yds. I don't know if I just got a bad one, but I guess it goes in the closet . If anything changes in the future, I will try to update this review accordingly.

Things I liked are 10 shot magazine. It worked flawlessly. The stock had a good feel to it, and while the scope was not much, it had a nice base that I transferred to a better scope (RWS 300S) for the trial .

It simply won't group. I have run over 200+ rounds through it, tried a dozen different brands, weights, and types of pellets, and haven't yet had a consistent grouping.

By CarlUSAJune 17, 2022

Think about the caliber before purchase. What are you actually going to use this rifle for? I picked the 177 because I was buying this rifle for pest pigeons and I wanted to safely shoot in my back yard. The 22 version would certainly be better for small game i.e. Rabbit, squirrel etc. After I adjusted the sights (no scope yet) and had a few days of target practice in the back yard, I was shooting cans at 25 yards. My wife and son were sitting next to me enjoying the beautiful day. I was 3 shots in to the second magazine shooting five shot 1/2" to 3/4" groups in and my wife said "pigeons" I turned toward the house and 2 pigeons were standing near the gutter about 20 yards out. I aimed pulled the trigger and and got a clean shot Clean through the lungs of the further of the pair. The other of course flew off. I haven't owned an airgun since I was a kid and that was a Winchester multi pump. At 63 this gun has amazed me and I'm having more fun with it than I ever did with the Winchester.

Easy to load 10 shot magazine


By pbUSAJuly 16, 2021

I put a few pellets down the barrel but considering the barrel orientation error accuracy was poor. AirGunDepot issued me an RMA and now am waiting for my return to reach them so they will ship a new gun.

Great 10 shot magazine system. Gun is quieter than I expected.

Mount the rifle barrel properly. The one I received was mounted with ends swapped. Chamber was at the muzzle and crown was at the breech.

By IssacUSAJune 27, 2021

Accuracy trick. Take the stock screws out and put lock tight on them . Screw them in to 15 inch pounds . No more . Put locktight on the scope mount and rings . Also on the recoil reducing rail. It took around 800 pellets for my fusion to break in fully . Shoots crossman hollow points very well . Quit putting it off , buy this airgun !

Affordable, lightweight and powerful .

The scope isn't the greatest . But it's free.

By BuddyUSAApril 28, 2021

As a kid growing up in the 80’s, this is the air rifle I wished for. The magazine works great for me. You do have to pay attention but the tradeoff is well worth it. Cocking takes a little effort but not bad at all. Had a hard time deciding whether to go PCP or give this a try. Glad I did. Very accurate with open sights. Wouldn’t hesitate taking small game out to 40 yards. I have the .22

Not really a con but buy pellets and extra mags if you can get them. Go thru a lot more ammo now that follow up shots are quick.

By K BMarch 4, 2021

I learned from a youtube video that you do not have to remove the magazine to load it and I just leave it in the rifle now. I also attempted to wash a tin of Benjamin pellets and they oxidized right away. That made them difficult to load in the magazine. Spread them out on some paper towel, spray with WD40 and roll around in a clean paper towel. Now they load just fine.

The 10 shot magazine is really nice. You do need to pay attention a little bit. I really like the open sights. That was the driving factor in ordering this rifle over the Gamo Maxxim. Using Gamo rocket pellets - 14.5 g with steel dome/bb tips - I have 6 shots touching each other and 4 more in an inch and half shooting open sights at 25 yards. I am not that good of a shot and this really impresses me! Overall I am very happy with this rifle in the first week that I have had it. I hope it stays as good as it is right now!

A few issues with the pellet feed from the magazine. But that is 4 or 5 in 200 to 300 shots. I think my paying more attention and maybe sorting some pellets will almost eliminate that entirely. I have had some weird misfeeds and pellets falling out. But that has been when I am not paying attention and probably breaking the barrel too quickly.

By Rod DavisUSAFebruary 3, 2021

I love this airgun. It's looks are awesome. Great trigger and outstanding accuracy. My home range is 40 yards and I am getting a quarter size 10 shot grouping with the. 177-Caliber. I put on a BSA 4x12 airgun scope and wow!

Great accuracy

Scope sucks

By JoseUSANovember 19, 2020

Should this rifle/mag feed and load most pellets? I've got several tins of various pellets and two different mags that won't load/feed.

asked Scott from USA

gamo swarm magnum 10 gen 2,how to refill air from the gamo.please answer

asked Marlon from Philippines


Robert from USA

Its a gas piston break barrel rifle, you don't have to refill air.

David from USA


Guy from USA

Can you put the Gamo Swarm Magnum 10x Gen 2 Magazine into the Gamo Swarm Fusion 10x Gen2 ?

asked Mike from USA

No. Different way the mag works.

James from USA

Yes you can actually. As long as its a Gen2 magazine and the same caliber.

Gregory from USA


Mark from USA

Does the Gamo Swarm Fusion 10x Gen 2 have the feature that prevents double load like the Gamo Swarm Magnum 10x Gen 2?

asked Mike from USA

Yes it does, that is actually one of the features that was added to ALL Swarm models that carry the “Gen 2” designation.

David from USA


Mark from USA

Will the RRR RAIL fit a reflex sight, like a weaver rail will?

asked Stephen from USA

the Swarm scope rail is 11mm dovetail scope rail. You would need an 11 mm to weaver adapter for most red dots.

Mark from USA

at what distance is this rifle on target

asked william georges


Ed from USA

The product owner's manual does not describe how to get around the magazine enclosure to clean the barrel. Do not want to damage this mechanism.

asked Larry Codner


asked thomas

I really like this rifle.I hade put about fifteen hundred pellets thru this rifle and it has preformed really well. I have had minimal problems with the magazine and have never had a jam. w however, it is pellet picky and not all gamos will shoot the same pellet well, but with the right pellet it is an accurate rifle. fairly light to carry and easy to cock. over all, I give this rifle a five rating.

Ed from USA

It looks like you have to remove the scope to shoot with fiber optic sights is that correct? If you remove scope after it’s been dialed in do you need to do that again or does scope go back on in exactly the same position? Thanks

asked Michael

Hi. Can the rifle be used without the scope? Just aiming with the front and rear sight

asked Mileidys


Guy from USA

How come nobody talks about the mach.1 any more ?

asked Mach a raynah

I am a little leery of the mechanism that flips the cylinder and loads the pellet. Has anyone had any problem with it being out of sync, damaging the skirt of the pellets or other issues?

asked Bob Cowgill

I am a novice at this, will I need to also carry a large airtank to replenish or does it operate on little CO2 cannisters? I just want to know what the cost is after I buy the rifle.
