Gamo Swarm Magnum Gen3i Reviews

The rifle is well made and the noise moderator does quiet it down some, it is still loud though. I got the.22 cal which is very accurate. I'm nearly 80 years old and though it's a beast to cock I can still shoot 1/2 inch groups at 25 meters.

I would like a picatinny rail option. The scope it comes is cheap and doesn't have a mil dot reticle. By the way I have had 3 scopes replaced under warranty because the reticle shifted due to recoil. I don't like the plastic magazines, metal would be better. The plastic trigger is functional but metal is better and a better trigger is desirable. I cannot adjust the trigger to break to my satisfaction, it just isn't smooth. I have an old (45 years) Feinwerkbau that has a smooth clean breaking trigger, Gamo can do better than this trigger.

The quoted .22 cal 1300 feet per second muzzle velocity is with PBA ammo. I found this ammo is junk, not very accurate at longer distances at only achieves at best 1178 fps in my rifle according to my chronograph. PBA ammo is expensive and shouldn't be used because it can possibly damage the piston seal.

I like everything about this rifle. Powerful.

Better scope with objective magnification

Excellent break barrel rifle. Very powerful. I love it. Definitely not for the weak!! This rifle gets a 100 from me

Rifle fits me great, is very accurate, has the power to kill rodents and more at seventy five yards, even farther if you're a good shot.

Wouldn't change a thing.

Powerful, 22, H&N Hornets, deadly.

Drop scope and deduct from price. Give customers an option here. Smooth out or omit oval, sharp burred hole under the trigger shroud. Very irritating on a firm grip. Would be nice to see an optional metal mag. Hornets need some coaxing into mag. Picatinny rail - my scope has already jumped back. So a dab of gorilla glue in the rail should lock it.

Yes, this is a BEAST to cock. Loud. But getting smoother after 40 shots or so. You can feel the damping effect on recoil - it does not jump back like my 177 Gamo Whisper - retired with barrel droop after three years of “fun” with that gun. But not for the varmints! Enjoying this 22 with three chipmunks from 30 Yards (Leapers UTG True Hunter 3x9x40) after I zeroed it in. Headshot was very impressive. WATCH after removing the mag - ALWAYS safe release another shot - I had one in chamber, so be sure you are not cocked.

First day and owning and put 20 pellets through it so still sighting it. Powerful, nice grip, loading cartridge so far is smooth operation, a BEAST. Extension of rail is helpful for eye relief back on rifle.

Lose the Gamo scope it comes with, directions could be more clear as it covers other models, it is heavy and LOUD. Add a Picatinny rail!

Cocking it takes two hands, I have a 70 pound test bow and this gun is a BEAST to cock, 22 is LOUD. Says medium noise level (?). Just sighting it with my Leapers UTG 3x9x40 True Hunter scope, breaking it in and so we shall see how accurate for varmints. Does have a recoil as expected.

Overall, it’s a great gun. I’ve only had it a few days, but I’m pretty impressed. It should come with two magazines.

Seems to be pretty loud and to cock it that 40 pounds is a lot when you have arthritis. Maybe it’s just me, but I’m having a hard time adjusting that trigger. You need a certain type Phillips head to get in there and not strip the head of the screw out. I wish it had an adjustable cheek piece.

Buy it it’s a great gun. Have fun.

This is a very accurate rifle. Light and easy to carry. The longest shot I made was a head shot on a rabbit at 76 yards. Nice small game air rifle. I have found the H&N hornet very accurate out of this rifle.

The trigger is too heavy and needs to be adjustable. More than one clip would be nice. The magazine needs to be adjusted so it takes various pellets.

I went with a Hammers Scope 3-9x40AO built for springer air rifles and it has been excellent. You will need something to lightly press the pellets the rest of the way in the magazine. The Gamo pellets go in the magazine the best but I got tighter groups with the
H&N Hornet and the H&N Terminator Hollowpoint.

I liked the balance and weight of this Gamo 10X Gen 3. The 10 shot mag is a great idea and a really helps to load the next shot quickly especially if you use it for small game hunting .

Dump the non adjusting parallax scope and add a better quality scope with parallax adjustment. This Gamo Swarm Magnum 10X Gen 3 deserves a scope than what it came with. The scope that came with my Gen 3 Eyepiece would not focus and the AO adjustment was not easy to set it was very tight even still without being able to focus it was a no starter to try and sight in. These problems were not worth time or effort to send back for a replacement. I bought a new scope with parallax adjustment smoother eyepiece adjustment and AO setting from 5 yards to infinity. 6 shots and I was hitting groups inside at 46 yards.

This is a quite a hefty rifle to cock and will give you a work out for a morning of 50 shots. Do yourself a favor and upgrade the scope you will enjoy this Gamo a lot more the one it comes with is not worth the time to mount.

This my first purchase of an air rifle. Love the quality and weight. Easy to shoot and very quiet. Very accurate.

Nothing!

On my first order the was rifle was delivered damaged. Contacted support and they provided me a return shipping label to return the product. Received the replacement within 6 days. Great support!

I like the style and feel of the gun. It is however my first purchase of an air rifle. I purchased the Gamo Swarm Magnum 10x Gen 3 Mult-shot Air Rifle.

I would definately change the plastic trigger to a Metal trigger and better trigger screw.

An overall great rifle and for me at 5' 6" 138 lbs and 70 yrs old was not difficult to cock. I purchased the .177 model and love it. Ready to get rid of the many squirels that keep trespassing in my yard.

I have the gamo swarm magnum 10x gen2 22 cal and all I can say is to all gamo fans or trying this air rifle for the first time give yhe rifle a chance to go threw the break in period once broke in you will luv it

Metal trigger and better trigger screw

Once it's broken in it will not jump so bad when shooting

Nothing

Should have bought a PCP rifle.

It has a trigger pull compared to a lanyard firing Heavy Artillery. Even using my shooting bench - a comfortable shooting position is hard to find. The reticle went sideways after about 100 shots. The tool to tighten the reticle lock ring should be shipped with the gun. Using a blade screwdriver gives me low confidence the reticle will not stay put. I should have saved the money I spent on this to buy a PCP rifle.

Fast and accurate

None

It’s not a toy.

I have a Gamo Swarm Mag Gen 2 in .22. Identical to Gen 3 other than a slight tweak to the actual Swarm unit. First off...absolutely tremendous power. Mine gets 830 fps with FX Heavy (18 grain) for 28 fpe. This tops my Diana 350 .22 by a few fpe. It is highly accurate as well. And at just under 7 pounds it is the lightest mag springer made, great if you are hiking/hunting.

Metal trigger that is a bit 'crisper'. It has a very functional trigger as is but could be improved. Certainly doesn't break like my TX200, my HWs, or any of my Dianas.

Be VERY aware this gun is hard to shoot accurately. My personal Gamo Mag is topped with a Hawke Endurance and total weight is 8 pounds 10 ounces. A super mag springer this light 'jumps' a lot on firing. Once you learn how to shoot it the gun will flat perform. A golf ball at 50 yards is a piece of cake for me with the rifle rested.

Power, one shot kills on ground squirrels . This rifle is very accurate. At 20 yards I can keep most shots within the size if a quarter. Being able to simply cock the rifle 10 times without touching a pellet is a great accomplishment.

I don’t believe there is an easy way to reduce cocking effort. No “free lunch”.

The $20 service only provides chronograph speeds of 20 shots. I was under the impression that the scope would be sighted in.
At 20 yards the pellets were hitting 2 inches to the right and 2 inches low.

Accuracy, velocity, nice scope

I like that I'm the only person in the house that can cock it. I like that it's fast and powerful enough to explode the Firebird targets. It's has more of a kick than my PCP rifles.

I wouldn't change a thing

I was surprised that it shoots faster than a .22.

Well made and accurate

Would like a better trigger

Some pellets don’t work

Very nice rifle with 1650 fps/ fast as 22 LR / most power for the price/ looked at lots of details and reviews and nothing can outdo this product for this price / Thank You !!!

Put some gold bands on it because it's golden!!!

can't go wrong for the power / price and quality.

Accurate, light, powerful, 10 shot mag.

Scope is ok but with the rifles longer stock i cant get a good site picture through it.

A little difficult to cock but ill take it for the power.
