We all hate stalkers.
Those who eat our food, live in our houses and leave trails that they were there for us to know.
Or those who sneak in our instagrams to see our photo, dig in our facebook profile and read every line of our tweets.
But in the hunting field, we want to be a stalker.
We want silence and stealth.
Because the worst thing is your prey run off right after you miss the first shot with the more-than-necessary sound.
And there is the gun named silent stalker.
Join me in this special review to see if this gun deserves that catchy name that sparks lots of curiosity (and excitement, too!)
The Gamo Silent Stalker Bull Whisper is powered by Inert Gas Technology (IGT). Gamo, not to be outdone by other air gun manufacturers, has made their own gas piston technology – IGT. While a spring-piston gun has tar and lube on the metal spring, the grease thickens when the temperature goes really low, a gas piston, on the other hand, needs no lube. Therefore, it won’t have any of the problems experienced by springers. Moreover, IGT gun has no spring torque, no spring fatigue even when you left it cocked for hours, and gives you smoother cocking . Finally, since there is no spring vibration when shooting, IGT rifle gives you smoother shooting and last longer than spring gun.
This gun is a single-shot break barrel rifle so it means that you can only shoot 1 shot at a time. After that, you have to reload the pellet manually for the next shot. Single-shot gun teaches you how to become better shooter: you know you have to make your first shot count because you have only one chance to hit the target before reloading for the second shot.
The barrel is rifled with helical grooves inside the bore to make a pellet spin. Spin makes pellet stable, improves accuracy and enhances shooting range. Moreover, Gamo Silent Stalker features ND52 – noise dampener technology that permanently fits on the muzzle and decreases the audible sound by 52% over the standard spring rifle. Having this amazing silencer on your rifle gives you lots of benefits: First, your hunting dog is less likely affected by noise. Second, it reduces recoil and muzzle blast. Third, it protects shooter hearing ability. And finally, it keeps sensitive neighbors happy while plinking in the backyard and will not disturb your shooting fellows in the range.
The Gamo Silent Stalker is available in both .177 and .22 caliber so you can choose which kind of gun you like most.
The stock is tactical, all-weather molded synthetic. Unlike woodstock which is heavy and easily affected by moisture and temperature, synthetic stock is much lighter and provides you stable performance in any weather condition. Besides, it’s virtually maintenance free so it is the top choice for shooters who don’t want to bother with stock preservation.
The stock is ambidextrous so the left-handed shooter can share the same joy as right-handed shooter when shooting. In addition, it has dual raised cheekpieces on both left side and right side to help your eyes line up faster with the sight. The stock is designed with thumbhole style: it provides more relaxed grip on your wrist by resting the stock on your wrist as opposing to holding the stock up with your hands. Thumbhole grip is best for varmint shooter and for anyone who spends lots of time on shooting position such as benchrest shooting.
With this rifle, Gamo has installed a new technology in the stock called SWA- Shock Wave Absorber. It’s adjustable buttpad with three removable absorption cells so you can customize it according to your own need. It provides up to 74% more recoil absorption than standard rubber buttplate. Now you can shoot comfortably and enjoy long-hours shooting without pain on your shoulders.
Since this IGT air rifle available in both .177 and .22, it uses .177 or .22 pellets depend on which caliber you choose. .177 pellets are cheap, lightweight and give you higher velocity so it’s great for plinking and target shooting. On the other hands, .22 pellets is heavier, more stable on its trajectory and has more than enough knockdown power for dealing with different critters so it’s perfect choice if you want to bring it to hunting field or get rid of pesky pests in your property.
If you prefer your gun with open sight, then you must be very happy: Gamo Silent Stalker Whisper’s iron sight is fiber optic sight with the use of optical fiber for the dot so it gathers and channels ambient light to the rear sight in the way that it’s brighter than dark surrounding. As a result, you could align the sight faster and hit more accurate, even in low-light condition like dusk. The front sight is fixed fiber optic, while the rear sight is fiber optic adjustable for windage (allow you to adjust the sight left and right) and for elevation (allow you to adjust the sight up and down)
In case you are not the fan of traditional iron sight, Gamo has installed 3-9x 40 scopes for dead-on accuracy. 40 is the diameter of the front lens, measured in millimeter. 3-9 is the magnification ability of the scope: it means that the picture you see through the scope is 3 to 9 times bigger than the picture you see without it. This variable power scope gives you confidence in long-range shooting, although the fiber optic sight is more than enough in my opinion.
In the past, Gamo customers have swapped out their triggers with after-market ones. No need to do that anymore. The Smoothe Action Trigger (SAT), is light years better than the previous version. It’s smooth and predictable. What will that do for you? It’ll improve your grouping because heavy, unpredictable trigger is responsible for delivering large group. You’ll be amazed at how good a shot you are when you shoot the Silent Stalker with the brand-new SAT trigger.
Gamo Silent Stalker Bull Whisper generates velocity up to 1300 FPS with .177 pellets and 975 FPS with .22 pellets. These are outstanding velocities compared to other air rifle on the market and it makes this rifle belong to the magnum class in the air gun world. Additionally, since the speed of sound is 1100 FPS (vary with altitude and temperature), you may hear the loud crack if you buy .177 caliber because the lightweight pellet breaks the sound barriers. If you buy .22 one then this is not an issue at all.
Does this IGT rifle meet the advertised velocity? Chrony tests have given us the results as follows: With .177 cal, Gamo Silent Stalker produces 630 FPS with JSB Exact Monster, 975 FPS with Gamo Magnum pellet and 955 FPS with Gamo Pro Magnum .

There are lots of customer reviews for this Gamo rifle. Positive reviews show that people love its IGT technology, smooth trigger, amazing accuracy, awesome power and relatively quietness (although not as quiet as “whisper”). Negatives reviews show 2 prominent issues with this gun. The first is the loud noise out of the box: but the sound level will decrease after the break-in period so be patient if you just shoot couples of pellets with this rifle. The second problem is the scope: They said it’s hard to achieve desired accuracy with the manufacturer’s scope. The solution is simple: Simple use the great fiber optic open sight or you can put your own scope on this gun.
The price for Gamo Silent Stalker is about 200 dollars.Considering its advanced technology, superb power and accuracy, and lots of awesome features like fiber optic sights, variable zoom scope, it’s very reasonable price in my opinion. At this price level, you’’ll have a lifetime gun that shoots as good as new for years.
There are a couple of different listings online with different prices but the listing I found with the lowest price is the cheapest price among online e-commercial sites like Amazon, PyramydAir, Walmart,etc.
This air rifle incorporates many Gamo’s new features into one lightweight package. It is powerful, accurate and the all-new SAT trigger is a huge improvement that Gamo’s customers have begging for a long time. The Silent Stalker is best suit for picky shooters who want to own an excellent gun with a stunning power and for hunters who want a trusted companion to go into the field.
