Gamo Swarm Maxxim Scope Combo
A lot of air gunners love their break barrels, whether it's nostalgia, power or accuracy - break barrel airguns have won the hearts of many over the years. But one thing has almost always remained the same with a break barrel, you can only load one shot.

The Gamo Swarm Maxxim air rifle builds upon previous attempts to create a multi-shot break barrel rifle that lives up to its promise.

Customary with many Gamo rifles, the Swarm Maxxim is has a gas-piston powerplant featuring Inert Gas Technology (IGT). This technology will give airgunners up to 1300 fps with only 30 lbs of cocking effort, but the real excitement is in the 10 round Quick Shot rotary-style magazine.

So if you're looking for a break barrel that gives you more shots with less hassle, check out the Gamo Swarm Maxxim air rifle!

Gamo Swam Maxxim Air Rifle Features
  • Gas-piston powerplant (IGT--Inert Gas Technology)
  • Breakbarrel
  • Single-shot
  • Rifled steel barrel
  • 11mm scope rail with scope stop
  • SWA (Shock Wave Absorber) recoil pad reduces felt recoil by up to 74%

Better than I thought
I bought this gun to replace a PCP that quit working after 5.5 years.... And I like it way more! No more pumping air into a PCP. One pump and shoot. Other reviews mentioned the scope was an issue. It did take a while to site in but I'm plinking accurately at 25-30yds. I've also knocked out a few chipmunks burrowing in my landscape. I really like this gun and would highly recommend it.
ProsAccurate, easy to pump, multi shot.
ConsTook some time to site in.
Best UsesRodent control.

Not happy with the scope .
Got my gun on Monday 4th June ,Got the scope on bore sighted it that night .Grandson and I went to the range Tuesday at noon.Got set up to shoot ,and shot three times and the cross hairs rolled to a X no fixing .Man we where pissed only three shots !!!!!! We had read the reviews on the gun and scope new the scope was cheep most people changed them out , But my god man three shots !!!! Called Airgun Depot yesterday Tuesday 5 .Explained what happened there response was pack it up send it back we will send you another in a couple weeks. I explained it was not the gun because we went ahead and shot 30 times just pointed and shot at target to make the trip worth wild gun shot great .I said want you just send a replacement scope Her reply was no can do . I spent 179 dollars you would think they would have said here a cheap replacement.If the scope would have lasted at least 50 shots and then quit I would have said read reviews scopes cheap but only three shots come on !! Called Gamo same thing send the hole unit back makes me wonder about there 3 year warranty . At no given time did ether company say heres a cheap 10 dollar replacement even .
ProsGun works as advertised shoots great .
ConsYou are only paying for the gun scope is junk !!

Very pleased - first air rifle since I was a child.
So far I am very pleased with my Gamo Swarm Maxxim. I made sure I cleaned it very well before shooting it. Took about 20 shots to get the scope zeroed at 25 yards. I know from researching it takes 150+ rounds to really season the bore and bed in everything for best accuracy. So far no complaints very happy with my new rifle. Certainly considering adding a .22 Gamo to my collection. Possibly another swarm Maxxim or the Swarm Magnum. The light weight RWS 6.9grn seem only ok accuracy. However the H & N Baracuda Hunter Extreme in 9,26 grn this thing really likes.
ProsGreat value for money. Great inexpensive plinking fun.
ConsNone so far.

Its a all around gun hunting small game, pest control, plinking, ......did i mention pest to shoot...has hitting power with the right size pellet . Gun excels in every situation with the right pellet....
Pros10 round clip, good power and grouping is tight.
ConsBefore you buy one, do your homework.....after i bought my Swam Maxxim..a days later while im still waitn for it to come in the mail they announce the ''New And Improved Gamo Swarm Magnum"....Didnt even shoot my Gun yet and theres a improved one just around the corner.....But the Maxxim is still a awwwwsome gun...
Best UsesWith the right pellet? Everything you can do in the back yard..

Great air rifle
Gamo swarm maxxim has done it this time. When I received this rifle, I was amazed by the power. After dialing in scope and experimenting with various weights and brands of pellets. My gamo .177 rifle was dialed in at 20 yds. Purchased a couple extra 10x cartridges and a gamo maintenance kit. To keep this air gun in top performance. Takes around 50 to a 100 shots to get good groupings, but with patience and focus this rifle will perform. Be sure to get some ply board for your targets, as the swarm will eat holes through the fence.

This is my favorite air rifle so far and I have several . I have.been shooting air guns for 50 years. Modern computer design systems and just air gun evolution in general have changed and improved these tools through the years. The Swarm is light , powerful and accurate as others have noted . I enjoy my modern break barrels because of their simplicity and RECOIL ... I just love that kick ... PCP guns do not provide that .
Pros All of the above ... of course the repeater function is revolutionary and has worked well so far for me ... too cool ...
Cons Funky scope but I put a Center Point 4X from my Benji collection on it ... SWEET ...

Repeat Shot Break Barrel Rifle
This is my first Gamo Rifle. The reason I buy it, is just to see how really works. The rotary magazine works just fine and hope some other brands come up with something like that. The other plus reason to get it was because is lightweight and will work batter for my old age. I got the ,22 cal. and after I try many types of Pellets from my Pellet tool box (I have 18 Air Rifles), I found out this Rifle like's the H&N Baraguda Match 21.14 gr. on the 50' about one quarter group. I hope Gamo learn how to make a batter Barrels!! But for $200, not much to say...Forget about the Gamo Scope, you are wasting your time. I hope was with a wood stock and look much batter. I had to buy extra Magazine. He could give us one and he could keep the Scope.
ProsRepeat shot and Lightweight.

Great gun
My first break barrel and I can't say enough good things about it. Purchased in .22 and it is more than powerful enough for the local small game. Had it sighted in within 6 shots. The gun is accurate and a pleasure to shoot. More fun than some of my powder guns.
Pros10 shot capacity. Good weight for stabilized shooting

All pellet rifles should be repeaters!
Having 10 shots is game changing. Sure there are PCPs that do this, but you literally need to carry a life-support with you if you want to shoot. That defeats the whole advantage of Air guns for me. I have lots of air rifles, pistols, and this is just a much better experience. It’s still a break-barrel, so it’s hold-sensitive and the scope is just alright. But it’s surprisingly easy to cock (because of the long barrel, once you figure out how to shoot it. Breaking it in is quick since you can shoot a ton of shots quickly. I didn’t clean mine before I used it and it was very backyard friendly. The main downside is that it feels a bit plasticky (because it is) and he stock is kind of ugly and boring. Hopefully Gamo will start putting this repeater system on all their guns so you’ll be able to choose a wooden stock model and other calibers. I saw a wooden version of this on YouTube for the European market, so AirgunDepot needs to convince Gamo to ship them a few 😄
Pros- Repeater works flawlessly. I’ve shot 400 pellets, at least, and not a single malfunction. - Backyard friendly, - Powerful, LOADS of fun, - Easy to cock (for a magnum gas piston).
Cons- Only one stock choice in the US and it’s kind of ugly and boring. - Very long

Nice Gun for 200.00
fun to shot with good groupings after you replace the scope that it comes with. I put on a Walther 4 power scope and the groupings went from 5 inch to 1 inch @ 25 yards
ProsSelf loading is great, fun to shoot
Consscope is junk, do yourself a favor when you get the gun and open the box grab the scope and chunk it in the trash, this will save you a lot of headache.

Very good
I bought this cause we have a raccoon problem, they get into our sheds destroy every thing and then get into our garbage cans, they even have chewed holes thru the thick plastic so they can pull it out and make a mess. Since shooting a few in the butt's they havent come back, so i am hoping they got the hint.

Multi-Shot Pest Control
One of my first air rifles was a Gamo Whisper break barrel. I bought it new for $81 but quickly discovered it had been used and returned and was missing the scope. Nevertheless, it quickly grew on me as one of my favorite rifles. It was a pleasure to shoulder, light, easy to cock and a relatively decent trigger. Now I have 11 air rifles, but no Pre-Charged Pneumatics. Recently, I have had some woodpeckers driving me crazy. and when they started pecking holes in my expensive, ornamental trees, I was bothered. Now they think they are musicians as they peck on my rain gutters creating a stupid one note symphony. So I grabbed my 177 Maxim and hit him with my first shot and he fluttered/fell to the ground. I was very glad to have the multi-shot capability so I could quickly cock and shot him in the head to minimize any suffering and ensure his demise. Obviously, it would have taken many extra seconds to manually reload a single shot rifle potentially prolonging a pest's suffering. Although I don't hunt, I would highly recommend this (or any other) multi-shot weapon for hunting.
ProsMulti-shot No air tanks or compressor needed Well balanced and shoulders well Composite stock, does not feel hollow Decent trigger Accurate Relatively low cocking effort
ConsCan shoot with an empty magazine, possibly damaging the weapon.

Excellent accuracy.
No problems with delivery services as the product was delivered ahead of schedule. Installing the scope was easy. It took me about 5-6 shots at 24 yards to get it on target. After about 30 shots over the course of several days, this air rifle was grouping 1-2 in. shots groups consistently. I noticed it took around 10-15 shots for the barrel to "break in". After that the groups became more consistent. I would grade the loudness as medium low. It is quieter than my first air rifle, a Gamo Shadow Sport, and definitely back yard friendly. The scope is sharp and is performing well. The ten shot rotary clip is easy to use and load. No jams so far.
ProsAll of the above. Mainly the accuracy so far.
ConsGetting used to using the rotary clip to make sure you don't double load a pellet. Just pay attention to the rotary clips shot numbering system which tells you how many pellets remain in the clip. Also, it is best to just not cock the barrel until you are ready to make a shot.

Great Rifle but Bad Scope
This is a great rifle. The quick loading system works great, and when the scope is working it is quite accurate. The scope will not hold sight. I adjusted the scope to hit the target dead center fired the rifle 10 times and hit right on target every time, then put the rifle away in a padded case, closed it up and left it over night without a bit if movement to case or rifle. Next day fired the rifle 10 more times and it shot low and to the left all ten times. Readjusted it and next day again low and to the left. Can no longer adjust the cross hairs. Will have to upgrade to another scope.
ProsGreat to have a break barrel rifle that loads more then one pellet at a time and works so well.
ConsReally bad scope!!!

after putting about 150 shots thru it and cleaning it 4 or 5 times she is now shooting at 30yrds. 5 shots can be covered by a quarter. That seems good enough to do a little hunti

Great Rifle!!!
Great idea and I can only hope more manufacturers come up with something similar. I own 10 Gamo rifles and like them all, but this one has the edge simply because of the magazine. it is amazing how fast you can go through a 10 shot cycle. I purchased mine in .22 cal. The CAT trigger is fantastic on these. I change out the rear trigger adjustment screw (Be careful if you don't know what you are doing) with a slightly longer, M socket set screw. On all the CAT triggers I set them at about 1.5-2 lbs max. The key is on all the GAMO's you have to find the right pellet. You wont hear this to often, by the best .22 Cal pellet for all the Gamo is the RWS SHP 14.2 grain. I have tried almost every pellet made and these simply work the best and still provide a good velocity. BTW the best .177 pellets are the JSB Diablo 10.34 grains. Amazing groups in my Maxxim (Non-Swarm) Under 1/4" CTC at 20 yards
ProsThe #1 Pro is obvious!!!.You have a 10 shot magazine on a break barrel! Doesn't get much better than that. It is very easy to cock.
ConsThe scope is junk. Upgrade it! You just can't put too long of a scope because the Swarm magazine limits your distance

Gamo Swarm Maxxim .22
It came with a bad scope. I could see target better with out the scope. You can not upgrade scope either because it is custom super short. The high tech loading device worked perfectly. It will not allow you to load gun with out magazine. It is accurate for $199. I sighted it in with out scope and it is fun shooting 10 shots so quickly and easily.
ProsLoading device delivers the goods
ConsCheap garbage scope No single loading

shot thru a steel can just like a 22/lr rifle would at 25 yds. very quite and very little recoil for the power. would have given it a 5-star rating except the scope has a lot to be desired (junk)

Works Wonderful!!
I'm new to air gunning. When I saw the Swarm, I knew this was the gun to get started on. I didn't like the idea of loading a pellet one at a time, no need to now. The magazine loader works great, had small problem,and Airgun Depot go that straiten out, Thanks. Sighted the scope easily and started to pink away.. My son is very knowledgeable about guns and he was impressed with the swarm. If you are just starting out or have a number of air guns, you should get this one also. For the price and all of the feature, you can't go wrong. Also Airgun Depot are the best to deal with. The info they offer through their videos and help, is outstanding.
ProsThe reviews on the Swarm are right. pop in the magazine and off you go.

gun is fantastic
had the gun for a week now, its a lot of fun with the 10 shot magazine. on problem I have is I never could get the scope I receive zeroed in. T adjustment didn't seem to move the scope to a position where I could hit a bullseye at 20 yard. even with the gun in a vice. I had to purchase a different scope. I am waiting for it now. with the right scope I believe it will be a great gun for all uses. definitely get a couple of extra magazines, they are really convenient.
Prosmagazine, light weight easy to operate breakbarrel
Consthe scope I received could not be adjusted

Best thing since sliced bread
The title is not far out, as the gap between a $1k at least outlay for a pcp (why does the p have to be silent as in swimming?), and a $200 break barrel? Hey presto, a $200 ten shot break barrel! I think it's brilliant, we are plagued by a plague of Iguanas in South Florida - thanks pet lovers! who release all manner of species for the rest of mankind to clean up!! Retards!! I regularly knock off ten at a time thanks to the rotary pellet holder. Need help though as these pests breed 40 young a year!! Yes, 40 each year......awaiting a Gatling version....

Game Changing Breakbarrel
This is one of those weapons that just got it all right! It just works. For the price it is unbeatable. A must have for anyone who enjoys airguns. If you take the time to learn how to hold it ( or let it float in your grip ) it is a reliable, accurate shooter.
ProsEase of operation. Reliable, Light weight. Great Value.

Reliable and accurate
The Gamo Swarm is now my preferred go to air gun. It has been extremely accurate and easy to reload and shoot. I bought extra clips and can got through a lot of pellets , so stock up. The cock and shoot made it a lot easier to dial in the scope as well , very little delay between shoots.

Got this gun a few days ago. Took 10 minutes to sight in the scope and then it was on. Have a major squirrel issue and this gun has served me very well. The 10 shot mag and quick reload are what makes it. Plus the weight is great not heavy gun is balanced well. So far I love this thing. Was looking at PVP guns but when I saw this for the price I was sold.

Best Choice
This Gamo Swarm is my first air rifle, and I believe I made the right choice. The rifle arrived earlier than the estimated delivery date. The packaging was perfect, no visible damage to the box and of course to the rifle. Thank you airgun depot. I knew that I must sight the scope as soon as I made my first ten shots to a target tin can about seven yards away, because I did not make a hit. I went to youtube to learn how to sight air rifle scopes. When I set a target with a cross mark 20 yards away, I found that shots were about 8 inches low. I then turned the elevation up by 180 degrees and made another shot. My hit was still about 4 inches down. Then I made another 180 degrees adjustment to the elevation, and made another shot. I hit the bulls-eye. I made more shots and they were all bulls eyes. Grouping within a penny. I did not have to make any adjustment to the windage. Long story short, sighting of the scope was a breeze. I am a small person and the rifle being 7 pounds is heavy for me. To break the barrel, I must put the butt on the floor and use my weight to bend it. The problem is not the rifle but me. Still I am a happy person for choosing the Gamo Swarm. It is very accurate and the noise is silent enough for the neighbors to hear. I plan to use the rifle for target shooting only. I cannot bear to use it to shoot or kill any creature, pest or pet. I wish I had bought more magazines when I bought the rifle to save on shipping. I go through one load of the magazine very fast. Ten shots is not that much. If I have five magazines, I think I will enjoy the rifle five times more.
ProsRifle arrived early and in good condition. Very accurate.
ConsOnly one magazine. It should come with at least two magazines.

I got fast service from airgundepot. .The new Gamo Swarm was in good shape , no damage to shipping box. I cleaned the barrel, installed the scope and in 30 shots , was hitting a quarter sized circle. I love how you can shoot 10 shots and all you have to do is cock the break barrel and you are ready to make a follow up shot.I have a squirrel problem and so far, the Gamo Swarm is doing a real good job on the tree rats. What more can I say!!! THANKS AIRGUNDEPOT.

Gamo Swarm Maxxim .177 caliber
At just under 7 pounds with a scope this rifle is very hold sensitive making it sometimes difficult to shoot accurately . I use Crosman Premiers 10.5 grain ultra magnum to tame the power output with good results, My scope had a reticle that would rotate so i replaced it with a 4x16x40mm side focus that is the same basic size and weight and it works very well . Like most break barrels it takes a great deal of practice to hold it the same way every shot , and it just makes you a more accurate shooter and makes you earn every bit of knowledge possible .Pcp's are so easy to shoot because theres just no recoil to deal with unlike break barrels . Because of bad weather and time constraints i have less than a hundred rounds through it so far but i plan to fix that soon , can't wait to her out hunting to see what she can do . So far the ten round rotary magazine hasn't missed a beat and it is so smooth. Im liking the overall light weight of the rifle since my Gamo Hunter Extreme .177 is at least 4 pounds heavier than the swarm , but a little easier to be accurate with because of the extra weight but harder to carry in the field . I use the same pellets in my Extreme also .
ProsLight weight . ten round magazine , fast follow-up shots .
ConsCheap scope mine had a reticle that rotated .If you prefer the wood / metal look this isn't it . At least 65% percent plastic this accounts for the the light weight . Practice up on the artiiery hold .
