GAMO Whisper Fusion Mach 1 .22 Caliber Air Rifle


By: Dr. Jim and Mary Clary


This is the most robust air rifle that we have ever tested.  The weight and balance are perfect, making it easy to get on target for a shot.  The following are some of the unique features of the Mach 1 that we liked:

First up is the Recoil Reducing Rail system (RRR™).  Most airguns have grooves for mounting the scope rings, similar to a lot of conventional rimfire firearms.  A common problem has been the inability to tighten the rings down to prevent slipping due to the intense recoil of high-power airguns.  That problem has been eliminated with a very secure 5-screw mounted rail (RRR™).  This "picatinny style" rail consists of two pieces that are separated by polymer struts.  The unique design of this patent-pending design virtually eliminates the recoil-stress on the internal components of the riflescope. 

And, speaking of recoil, the Shock Wave Absorber (SWA™) recoil pad is just as effective as the Limbsaver™ pads on our high-power hunting rifles.  There are very few airguns that bother putting effective recoil pads on their guns.  Most simply use a piece of molded rubber to cover the butt stock and call it a "recoil pad." 

GAMO's Whisper Fusion™ technology was designed to quiet down their spring-powered airguns and mitigate the "twang."  That technology was also applied in the Mach 1.  Without it, the sound of this airgun would rival .22 caliber rimfire rifles. 

The conventional spring power plant found on GAMO (and other) airguns has been replaced with a new 33-millimeter pneumatic cylinder.  This is called the Inert Gas Cylinder (Inert Gas Technology - IGT™).  When cocked, it compresses the air to deliver a consistent pressure which propels a .177 PBA pellet to a velocity up to 1,420 fps and a .22 PBS pellet to a velocity up to 1,020 fps.  We confirmed the latter velocity with our Caldwell Premium Chronograph. 

And finally, the folks at GAMO have given us what we have been asking for:  An adjustable trigger.  The Custom Action Trigger (CAT™) allows the shooter to independently adjust both the first and second stage of the trigger.  It is great, and out of the box, the trigger pull was set at 2.25 lbs... incredible for a "standard" airgun.


All that remained for us to do was to shoot the Mach 1 for accuracy.  For that, we selected GAMO Red Fire pellets.  We have used these pellets before, and they are not only lethal but very accurate.  

After "dialing in" the rifle at 25 yards, we shot for accuracy with our Caldwell Lead Sled.  To state that this gun is a "tack driver" would be an understatement.  We consistently shot groups of ten pellets that measured under one inch in diameter (center to center).  

Having hunted squirrels in the deep woods of Alabama, Mary can tell you that when the bushy tails are high in the canopy, it is not uncommon to require two pellets to bring them down.  A friend of hers, Fedor Palacios, was at the GAMO Squirrel Master Classic in February and brought down two squirrels with one shot each using Red Fire pellets and his Mach 1.  Ok, we'll admit that Fedor is a good shot... but, if the Mach 1 and Red Fire hadn't been such a lethal combination, he might still be shooting at those squirrels.

**Note: Some break barrel action guns may be harder to initially cock then others.  It may take added force to break open the barrel for the first few uses.  We recommend that you break it open, not fully cock the gun, 10-15 times to loosen the barrel and make it easier for future use. 

Before we close out this article we would like to mention the new GAMO ProShot ID System.  This reference system was devised by GAMO and is unique to the airgun field. .  It labels the best application for each rifle in their line AND it matches the various GAMO pellets to those applications.  The system involves three color codings: Red, Green & Blue.


Provides accuracy and high velocity - ideal for nuisance animals such as mice,rats, birds, and snakes.  Also perfect for recreational shooting.


Delivers accuracy with higher energy downrange for ultimate impact and             penetration -- ideal for small game such as rabbits, squirrels, Racoons, and crows.



Offers the ultimate in accuracy and consistent performance -- ideal for both training and competitive shooting.

The ProShot ID System by no means indicates that a particular gun can't be used for one of the other applications.  It is a recommendation to help the consumer decide which gun is right for them.  And, since the GAMO pellets are also color-banded, we no longer have to guess which pellet is best for our shooting.   We just look for the appropriate color marking on the package and pay the clerk at checkout.

About the only thing that GAMO can't do for you is shoot the gun.
