Breakbarrels are among the most popular airguns purchased by shooters who are getting serious about airgunning. They're powerful, accurate and consistent right out of the box - but repeating shots? Forget it! Over the years there have been many failed attempts. The last time anyone made a successful go at it was over 10 years ago with the Diana 300R Air Rifle.

The Swarm “breaks” (see what we did there?) into the market with an elegant solution, never before achieved by airgun manufacturers - a breakbarrel with a 10 shot rotary magazine that slaps a round into the chamber every time you cock the barrel. Did we mention this gun is fast? With a mere 30lb cocking effort you’ll quickly find the ability to fire repeating shots without a single shot reload can be pretty addicting! You’ll wonder how you ever managed to keep sane loading one pellet at a time!

The Swarm Maxxim maintains a consistent velocity of 1300 fps in .177 and 975 fps in .22 caliber (yes, yes, using the lead-free light ammo). As a gas-piston, this gun is easier to cock, operates in cold weather and has less recoil - a feature enhanced by the Shock Wave Absorber recoil pad. A 3-9x40 scope is included and mounts onto Gamo's Recoil Reducing Rail (RRR) 11mm Dovetail, built to reduce recoil stress on your new optics. These features combined with the all-weather synthetic stock and Whisper Maxxim sound reduction system, make this airgun ideal for small game hunters and those who want more target practice and less reload time - especially if you grab an extra magazine.

Is a quiet breakbarrel that spits out 10 shots as fast as you can cock it “just another breakbarrel”? You be the judge!

Verified Purchase

Things I liked: 95 rounds fired and I am impresed. Easy to cock ,reloading device worked flawless, and the accuracy was great ,velosity was low may improve as it gets broke in. 15 yard range (indoor ) turned scope down to 5x to clear up focus. And it is lighter than my Benjamans. Scope adjusted easy definent clicks, I was on Bulls Eye the fith shot one half in high. held zero so far. It likes Gamo wad cutters 15.4 gr. Of corse it is early for a review know more later.

Things I would have changed: SCOPE If gamo put a beghter scope in the package the price would go up. so leav it like it is. May find flaws later. Receiver is very short , Replacement scope will need to be short . open the action to get the lense caps on now Are sling swivels needed. could easily damage loading device looks fragile. Picitinny scope rail on top of their system would make scope changing easy. Copy Benjaman and crosman.

What others should know: Single shot Benjamans are FUN . Try A GAMO Swarm MORE FUN and More pratical to hunt with. This is a 22 cal. Review date 12 2 2018

Things I liked: - Easy/automatic reload - Look and light weight - High accuracy (depending from the pellets choice: from my side I for a good accuracy I used FX airguns pellets)

Things I would have changed: - Small scope for long range and precise shooting sessions - Not easy to install bigger scope with the reloading system (not all scopes can be installed)

Things I liked: I like the way the gun feels but it ends their

Things I would have changed: Make the clip mechanism work

What others should know: The gun works ok if you take the whole clip mechanism off and shoot it as a single shot shooting it this way don't waste you money but a better gun I wish I would have

  • Brad from USA asked:

    My son is 8 and has been shooting bb/pellet guns, as well as .22 rifle and .410/20 hunting squirrels. I am going to get him the swarm maxxim and on the fence about .177 or .22. I know both can take down squirrels and rabbits. The .177 shoots flatter. .22 carries a heavier punch. With the right pellet are they equally accurate? What info can you share to help fall to one side of the fence?

    • Tyler from USA:

      The .22 would be the better choice for small game. Hands down

  • Peter from USA asked:

    I have the .177 version of the Swarm and noticed the pin pushing the pellet into the barrel does not push the pellet in all the way. If I dont finish it off with my finger, the rest of the mechanism will deform the pellet skirt when I rejoin the barrel to the rest of the rifle. Are there any mods or upgrades to the push pin that can be done so the ammo will push into the barrel the correct distance? For reference I am cocking the barrel all the way down to the mechanical limit and the scope is not touching the pod at any time. Other than changing out the push pin/rod I dont see any other way to adjust the depth the pellet is loaded. Are there longer pellets that i should be using? I'm currently using Crosman Destroyers .177

    • Tyler from USA:

      I would recommend contacting Gamo (or the retailer you purchased the gun from if still within their return period) as that sounds like a defect. The pellet probe should be seating the pellet all the way into the barrel.

  • Malcolm from Trinidad and Tobago asked:

    Is this rifle smooth bore in the .177 calibre or spiral ....I need to know for my country ?

    • Tyler from USA:

      The barrel is rifled
