Swarm Magnum 10X GEN3i Break Barrel Pellet Air Rifle - IGT Mach 1, Inertia Fed 10-Shot Magazine, High Velocity .177 or .22 Caliber Airgun - Black

Alright, let’s talk about why the Gamo Swarm Magnum 10X GEN3i Inertia Fed .22 Caliber Break Barrel Air Rifle is hands-down one of the most awesome air rifles out there. If you’re into power, precision, and just flat-out fun, this beast delivers in spades. First off, the power—this thing slings .22 caliber pellets at up to 1,300 fps with alloy ammo. That’s serious knockdown force, perfect for small game like rabbits or squirrels, or just obliterating targets in your backyard. The IGT Mach 1 gas piston is the heart of it, a 33mm cylinder that pumps out consistent, jaw-dropping velocity with way less vibration than a traditional springer. Smoother shots, less fatigue, and you can leave it cocked without worrying about wear—try that with a lesser rifle. Then there’s the 10X GEN3i inertia-fed magazine. Ten shots without reloading? Yes, please. The system uses recoil to index the next pellet, so follow-up shots are lightning-fast and seamless. It’s like having a semi-auto feel in a break-barrel package—revolutionary stuff. Load it up, break the barrel, and you’re ready to rock again. No fumbling with single pellets in the cold or heat of the moment. Accuracy? Oh, it’s there. Pair it with the right pellets (Gamo Red Fires or some heavy hitters like H&N Barracudas), and you’re drilling tight groups at 25-50 yards. The two-stage adjustable CAT trigger lets you dial in the perfect pull—crisp, clean, and tailored to you. Add the included 3-9x40 scope, and you’re picking off targets with precision that’ll make your buddies jealous. And let’s not skip the Whisper Fusion tech—dual sound moderators make this one of the quietest in Gamo’s lineup. It’s not silent, but it’s stealthy enough to keep the neighbors from griping while you dispatch pests. The all-weather stock feels solid, with a grippy texture that’s built to handle whatever you throw at it. Cocking takes some muscle (41 lbs of effort), but that’s the trade-off for this kind of power. Once you get the hang of it, it’s a small price to pay for a rifle that hits this hard and shoots this well. Whether you’re hunting, plinking, or just showing off, the Gamo Swarm Magnum 10X GEN3i is a game-changer. Pure, unadulterated airgun awesomeness.

This is a powerful air rifle, probably too powerful for what I need, but my last air rifle was 40 years ago & things have come a long way in the mean time! On reflection I should've bought the less powerful Swarm Whisper, but like I said I wasn't aware of how far these Nitro Piston rifles have come....not that I'm complaining! It handles well, seems robust, trigger is usable (hopefully it improves with use) & yeah, powerful! It is noisier than I expected, but this thing throws pellets HARD. I'm still zeroing in the scope, but accuracy certainly seems to be there with GAMO Red Top pellets. The scope is cheap & basic, but it works fine, being nice & clear, bright, holds zero & has a good zoom range. I see no need to replace it so it's staying on there. I have to say that I'll probably add the Whisper version, too, as I'm using it for rodent control & for smaller vermin like rats that'd be better, with the Swarm Magnum in 22 cal being best for longer ranges & bigger sized targets. But I'm keeping this one, oh yeah I'm impressed.

This pellet rifle is wonderful, especially paired with the Gamo swarm 10x hollow point pellets. I'm hitting targets at 50y no problem. The scope is OK, but I've ordered me an upgrade. The cocking weight is quite stout, so that will be a drawback for some people. You might want to go ahead and clean the bore when you receive it, mine had some residue from factory testing. So far from my testing, I've had great accuracy from the Gamo swarm 10x pellets, and the Gamo match wadcutters. One pellet for plinking and target shooting, and one for hunting. I have to really push the match pellets into the magazine, but they chamber just fine. There may be some sharp edges in the molded stock seams, just take a sharp edge and trim it back. The rifle is quiet for the power it shoots at, but it definitely isn't silent. Be aware of that. All in all, great gun. Super fun to shoot, and worth every penny.

I paired this air rifle with h&n Barracuda Hunter Extreme pellets. Accurate and devastating to squirrels. Makes ethical one shot kills consistently . The break over is a little stiff and the rifle is a little long but, over all it seems to be a really good rifle. The 10 round mag is Awesome !

Picture perfect item with very good packaging and fast shipping

The Gamo Swarm Magnum is an excellent air rifle , an acquaintance has one and it is accurate and powerful. The one star rating is due to the package arriving resealed, missing the 10 shot magazine, missing the 3x9 rifle scope, and a small chip on the rifle itself. To be fair the merchant refunded the full purchase price and advised to keep the damaged rifle.

First of all, wow. This rifle has phenomenal power. I’m new to the world of modern air rifles, and I was quite surprised by just how hard this rifle punches- and kicks for that matter. Not that it kicks as hard as even a .22 powder rifle, but I was still surprised to feel the recoil on my first few shots. So far, I have put 50 H&N Barracuda Hunter Extreme 18.52 grain hollow point pellets through the rifle, and I’ve got it pretty well sighted in. I didn’t want to use a bench since I won’t be using a bench in the real world, and it feels like the recoil might be adding some inconsistency into the equation. But then again, it’s still very accurate and I haven’t gotten it properly broken in yet, much less settled on the most accurate and consistent pellet type. The rifle is much louder than I expected, but I am not experienced enough with modern air rifles to make any determination or comparison as to how loud it “should” be. What I can say is that I bought this for eliminating pigeons in my back yard, and I went WAY overboard. I wanted something that will instantly and ethically dispatch a pigeon, and a well-placed shot with this will more than achieve that goal. But as I am in a neighborhood, this may actually be too much power and also be a bit too loud to just start plinking like I had expected. I feel a bit naive, and that I didn’t do adequate research for my specific purpose, but that should not take away from the quality or amazing-ness of this rifle. I’ve now read reviews of this thing taking out coyotes, and I do not doubt it one bit. Highly recommend for its intended purpose of hunting! Plinking pests in the back yard might warrant further consideration.

Love my Magnum! Very powerful, very accurate. It is a bit stout to cock but the power this thing has is well worth it. I have found that mine likes the Gamo Red Fire, and Gamo Rockets. 1" groups at 35 yards. The scope is nice but after around 250-300 shots ,the cross hairs started to rotate inside the scope. Called customer service and told them and they sent a replacement out same day. Very good customer service! It is a Magnum and you will find out that these high power springers are very hard on scopes, I've researched and found a Zero Recoil scope mount that will save your scope, and you can use any scope with it, not just an airgun scope. Hope this helps if you are deciding to get one, and I highly recommend this gun. It's a blast to shoot!
