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!

Things I liked: I paid for the scope mounting and PA did a great job, great accuracy right out of the box! the gun itself will stack them all in one hole at 20 yards if I do my part.

Things I would have changed: Not really impressed with the repeater/ loader right out of the box, failed to load 4 out of 10 pellets on every attempt. It actually seems to dump some of them out before the breach is aligned, but I will clean and oil the gun before I make final judgement. I was surprised that there was no literature with the rifle, maybe when PA installed the scope and put it in their case they neglected to include the documentation. (The rifle wont fit in the original box with the scope mounted.) Considering how new the idea of a repeating break barrel is, I would think there would be some literature to guide the consumer in proper care, cleaning and possible adjustments of the magazine and loader attachment.

What others should know: I love the way this gun shoots, quiet and accurate, I couldn't ask for more in this department! That being said, beware that this repeater is new and may need to be revisited by the manufacturer to get the bugs worked out. the scope is actually pretty decent considering the fact that its included in the bundle, in the past bundled scopes have been pretty dismal. I really don't want to come across like a jerk but some literature would be nice, I will try the Gamo USA sight and see if I can get a PDF.

Things I liked: Great weight, minimal cocking effort , great loading mechanism.

Things I would have changed: More power, compared to trail np2 . Other than that great gun.

What others should know: Be aware when the magazine is empty, since it is so easy you can dry fire it.

Things I liked: 10 shot magazine.Light weight.Accuracy.

Things I would have changed: Better scope.Extra magazine.Make the rifle body longer so a better scope(longer than 12.75 in.) can fit.

What others should know: Even though it said in the description in this page that the scope length is 13.5 in.,it is really 12.5 in.The max. length for another scope to fit in is 12.75 in.There are few scopes that will fit, and only one I had found with 12x magnification and A.O.(Bushnel Banner 12x40.without mildot reticle)After changing the scope and zeroed it, work fine.(the scope cover will not fit unless you cut the inferior part )For me the best pellet tested from 7 options was the Hatsan Vortex Express 13.12 gr.Give an avg.786 f/s( 18 pounds/feet2) and 1/2 in. group at 20 yards, 3/4 in. at 30 yards and 1 in. at 40 yards.2nd best the Hatsan Vortex Supreme 14.66gr (just like the H&N FFT) and 3d the Crosman premier domed 14.3gr. It is fairly quiet and very accurate.This rifle tends to work better with lighter pellets so the wind will be your limiting factor at longer distances.And not having mildot reticle is also limiting at long distance.I had shoot 350 rounds without any problem with the mechanism.

  • Bong from USA asked:

    Hi, I've read somewhere in the Web that some Gamo break-barrel's breech blocks can easily get broke, made from some kind of soft metal (pewter perhaps? If u may call it that). Would like to know if the breech block on Swarm is already made of steel (hardened steel will be most welcome :)), this is only thing left that hesitates me to buy, the rest of the features I'm already ok with.

    • Alvin from USA asked:

      I just got this rifle yesterday. Is there a instructional manual for it? I couldn't find one in the box. And also, there is a small 1/16" allen wrench attached to the side of the box. What is used for?

      • Stanley from USA:

        The 1/16" allen wrench is for the first stage trigger adjustment. Second stage adjustment is a small phillips head screw .
