Gamo Swarm Magnum Pro Gen3i Reviews

Tell us what you think
Great starter, break barrel rifle. The scope out of the box was spot on after zeroing with about 10 shots. I use this for iguanas and the accuracy is amazing and does a great job for small/medium iguanas. However for larger iguanas this is not ideal, not enough FPE to penetrate the skulls of the larger iguanas. Other than that this gun is a steal if you ask me. The break barrel is a little tough for teens though.
higher power FPE would be nice but for a break barrel this is probably one of the best break barrels out there.
Very accurate when you first start shooting it.
Better rails and hardware. This rifle comes setup with the worst possible mounts and hardware.
I've had this rifle for about a month. I've put about 1k rounds through it. It was very accurate at first, but then it ended up pretty much just blowing my scope apart. Got a new scope... Wouldn't zero. I inspected the whole rifle just to find that both stop pins on the rifle had bent and dented their housing. The jousing on the rail itself and the housing on the receiver. This is not a bad rifle. It just comes equipped with some of the worst parts and hardware. All the hardware for my rails and mounts are bent. Don't be thrown off by this review. This rifle is a great rifle. Just purchase better mounts and rails when you order it.

I’m still in the break in period but I think I’m pleased with the whole package. I really have high hopes for this to be a good rifle.
Excellent rifle

10rd cartridge, scope, accuracy, overall design
Although I am 70 yo, retired Military, decorated marksman, n healthy in general, the break barrel force is practically too much for me. Can anything be done? Don’t won’t gas or Powder assisted guns. This rifle requires two hands, full strength of both arms n the proper positioning of the stock to actuate/cock the piston!!
Pyramyd Air provides excellent communication, website, great deals, and fast delivery service! Highly recommend
Quality build. To Heavy for a average female's or older person. (I had my wife and her friends pick it up.) I lift weights and the break on the barrel is over 45 lbs. Haven't fooled with the trigger yet still getting use to it. Attempted to use the scope but not luck in getting it dialed in. I put a better one on.
Better scope. Or just don't include it.
Still breaking it in and matching pellets to the barrel. So to soon to comment on how accurate it is. And you better work out with lat pull downs to cock the break barrel . Not kidding get strong or you will not be shooting long.
Excellent sound suppression for followup shots
Trigger hype not all that good unless you go but longer screws
Dead after 2 years of Arizona, pistolgrip stock comfy for automatic but not a nitro
Accurate and easy to use

You’ll love it
I only took a handful of shots (without even zeroing in the fine scope sold with it) and it was astonishingly accurate. It looks like a real monster rifle and handles like one (it's heavy). It just looks impressive, and acts like it, too. The new-fangled magazine is pretty impressive, too. Insert, then cock-load-shoot. Ten times.
Add a warning to the verbiage on its web page that you have to be either a bodybuilder, weight lifter, Superman, or person in otherwise extraordinarily good physical shape to even begin to break this barrel. It requires a force I in my elder dotage (=old f*rt) am unable to muster. It was a challenge just shooting those few rounds because the exertion necessary to break the barrel was so extreme I had to sit on my posterior at home for a couple hours in my adjustable sofa after coming home from the range, causing me to bemoan and bewail my decrepit fate. This is not a rifle for a child or even a young adult who lacks olympic-force strength in their arms.
Only buy it if you are in very good condition. It requires a sh*t-ton of strength to cock it. Pyramyd agreed to the return for a refund minus their cut of the take. I instead will be buying the Gamo Swarm Fusion Gen 3i because Airgun Annie says it's easier to cock. But my goodness it looks pretty cool.
Easy to operate plenty of power for hunting all you need is pellets
Excellent design I wouldn’t change a thing, it would be nice if it came with two mags
