Gamo intended the Mach 1 rifle to be the standard for stealthy hunting and accurate shot placement, the Gamo Whisper Fusion Mach 1 air rifle is a leader in quiet shooting. Outfitted with a 3-9x40 scope, it's a hunter's dream when it comes to quiet, precise shooting. The Whisper Fusion Mach 1 air rifle combines some of the most advanced technologies Gamo has to offer. Whisper Fusion double-integrated noise dampener reduces report by 89.5%, and the IGT Mach 1 power plant delivers more velocity and terminal strength. The Gamo Whisper Fusion Mach 1 features the Whisper Fusion sound moderator, which allows pellets to travel through two different chambers that combine to compress and prevent noise expansion, resulting in the quietest Gamo power plant available. With all of the technologies that Gamo utilizes during the manufacturing process, this is one of their most effective break barrel rifles to date, which makes it perfect for pest control to target shooting and everything in between.

I just received my new rifle yesterday and, while I'm very happy with the overall quality of workmanship, the fit, and look of the gun, it won't shoot an accurate group at 20 yds. I began firing JSB Diabolo Exact Jumbo Beast .22 Cal, 33.96 grain pellets with the scope mounted. The gun was well supported with Caldwell DeadShot shooting bags. Wind was very light and downrange. The first group was over 8 inches! Firing several more groups yielded similar results. I also tried firing H&N Baracuda Match (5.51mm) .22 Cal, 21.14 grain with no change in accuracy. I checked and tightened all of the scope mounting screws and the picatinny rail. The tightest group achieved was just over 4 inches. I decided to remove the scope and see what the iron sights could do. The results were the same-very random. I began wondering if I just needed to fire a bunch of rounds through it and see if it "settled in". After around 100 rounds the results were only slightly better.

What can I say? A gun that won't shoot straight isn't much good. When I failed to get an acceptable group, I really began to focus on gun support, site alignment, site picture, breathing, trigger squeeze, and gun tilt. I'm willing to admit I may fire a bad shot once in a while, but I'm confident I was making very good shots here.

This gun is an excellent buy. Just beware that alloy pellets will go supersonic even in the .22 caliber so stick with lead.

Scope is actually very good and well matched to this gun. The gun is very accurate once you master the correct hold and find the right pellet and allow the piston to break in. Excellent groups at 25 yards always quarter size with very few flyers.

Just make sure to use heavier pellets. I have had the PBA pellets go supersonic and I own the .22 caliber version and it’s extremely loud when this happens. Not at all neighborhood friendly if you use alloy pellets. The groups aren’t as tight anyways when they go supersonic. I’m assuming it messes with the stability or something. I found that most leadpellets stay subsonic. The Ruger pointed pellets are very accurate as are the raptor pellets in my gun.

Best break barrel I’ve owned. I bought this for the silencer, very nice open sights, and lightweight. Dime sized groups at 25 yards WITH IRON SIGHTS! None of my Benjamin’s have iron sights- so they are useless once that recoil destroys the factory scope.

Lightweight, very accurate, ergonomics looks cool! Love the fiber optics easy to see open sights.

It is quiet, the only loud part is the action-that gas ram. And if your shooting wood expect a big loud WHOMP

By matthew t.June 27, 2018

Could be quieter, I have a Benjamin Rogue Which is rated at 87 level of two rather than a one as a gammo is And they both sound the same and I pretty much interchangeable. I honestly think that both a bit overpriced and is going to go for about 180 at the most. So you might want to buy them when they�re on sale. Additionally it�s a shame they don�t come with scopes which are already sighted And lock into place with accuracy already determined by the factory. In a time when we have self driving cars It�s a shame scope accuracy technology is still in its infancy Which shows a lack of an initiative to spend money on the manufacturers

Picked up one over the weekend and thought the gun was broke. Had a very hard time keeping ant type of a group with flyers high , Low, Left ? Took back and picked up a 2nd and just about the same as the first. Figured I'm just going to shoot about 1000 and see if it breaks in a bit. Trigger is a little stiffer then my old whisper turbo but I can live with it. Just too good of a deal at $199 plus a 5 year warranty to at least give it a chance. Seems to be shooting a bit better after about 400 shots. mine is also the .22 cal. Used the gamo pointed, some dome shaped, and also crossman dome pellets and all about the same with the flyers.


Hard time keeping a nice group at 17 yards from a rest.

By SaromUSAOctober 3, 2016

Shot about 700 pallets with gun so far and love it. It is accurate, light, good trigger. The scope that came with gun is ok. There is no automatic safety lock and it is loud. I would rated at medium high. That is why a 4 stars. I don't recommend shooting it in the back yard. I've shot all the rounds at 20-22 yards and haven't test farther out yet. It is very picky about pallet. I found the premier hollow point 14.3 grain work best, Benjamin destroyer 14.3 gr came in second. For the price, I think there no other gun can beat it. I paid 220 at cabelas.

Accurate, ligh weight, optic sight is great, scope, good price, great trigger

Little loud, I don't know why they put the word Whisper on it.

This is a great air rifle check out my shooting review on YouTube along with my other content!

Pros is the place to go for all things airgun!

By gwJuly 9, 2016

Very accurate and lightweight. Does not have 'Automatic cocking safety system'.

By BillJune 26, 2016

Took a while to sight in, but once I did, it is deadly at 25 yards and packs a punch A little finicky with pellets, but I found the red tipped Gamo hunting pellets to work the best, along with H & N ballistic.
