Gamo's original Whisper air rifle was an incredible rifle that just about took over the spring gun market. It's hard to believe they could improve it, but they did!

The Gamo Silent Stalker Whisper is an engineering wonder because of Gamo's IGT gas spring. The Inert Gas Technology makes the Silent Stalker Whisper a superior hunting machine that performs reliably in any weather, under any condition and for years without any maintenance. Spring guns are notorious for not performing well in very cold weather. Guns with metal mainsprings have tar and lube on the springs. Tthe greases thicken when the temperature goes real low. A gas spring, on the other hand, needs no lube. Therefore, it won't have any of the problems experienced by springers.

Besides the gas spring, Gamo's Silent Stalker Whisper has the same ND52 technology found in the rest of the Whisper series. ND52 is a noise dampening system that permanently fits on the muzzle and decreases the report (noise) by 52% over springers without the system.

Excellent Rifle
February 11, 2012
I chose this rifle primarily for muzzle velocity and advertised noise reduction. I do not have the instuments for meeasuring the pellet speed, but if penetration depth into a pine 2 x 6 is any indicater the muzzle velocity with PBA pellets is probably accurate. Gamo also maufactures a PBA "armor piercing" pellet that will hole thin sheet metal. The scope is of average quality, but is good enough for my needs at the moment. I checked the open sights after removing the scope. They adjust easily and are as accurate as the shooter. I've read some reviews that have complained that this model is louder than their old rifles. This is probably true if one is shooting PBA pellets. Keep in mind the high velocity of the pellet as it leaves the barrel. At 1300 fps that pellet is going to be loud. I use a lead domed pellet instead of PBA for target practice and it fires quieter than any air rifle I have ever owned. I have found the Gamo Silent Stalker IGT to be an excellent air rifle.
Light weight and accurate. High muzzle velocity.
Mediocre scope.

Can`t miss with this one!!
February 18, 2016
I thought my GAMO Silent Cat was the "cat`s meow" but this airgun, with the exact same synthetic stock is even better! Super accurate if you can work with its mediocre scope. Quiet and plenty of power! The IGT piston works great and there`s really nothing to complain about with this airgun. Get it refurbished (Sportsmans Guide, or try Pyramid), for under $140, its better than new!
Power, accuracy. Price(providing you get it refurbished/reconditioned)
Scope could be better, but is perfectly adequate. You`d really have to nitpick to find anything wrong with this airgun, given its price

Scope issues
September 27, 2015
Purchased new. Scope wouldn't stay on target. When I removed the scope I found that the rails were damaged because the scope moved, even though the screws were tight, because I'd checked several times. Rifle also damaged under rail. Appears that scope is fine, but mount is definately inferior. Pics to follow. Your web site will not let me send Pics.

Problem is the free scope, quick fix
February 26, 2015
The rifle is very powerful and accurate but the scope needs to be hard set set for each distance you want to be dialed in at. For example I dialed in the scope for appx 25 yards by shooting and then adjusting based on the grouping. This isn't rocket science and most people know how to sight the scope. Where I and most people get frustrated is the scope loses accuracy on it's own in a bad way. I was mortified when the lens cap nearest my eye popped off after a shot. Upon investigation I leaned that by adjusting the distance in the scope so many clicks downward, closing the distance between the lenses inside the scope, they became loose with play inside the scope housing. That is why it is zeroed in for one grouping and off the next. The gun is actually very accurate. I could see where they used threadlock to secure the locking ring but it had broke loose. You have to unscrew the lens cap, remove the locking ring, clean the threads, reinsert the lenses and then use threadlock again to keep it at the distance you are zeroed in at. I tried it without the threadlock and only a few shots later the lenses had shifted, the cap popped off again and I was off target again. I realize now that if I want to change distances I will have to readjust the lenses and threadlock the ring and cap again. The only cool thing is what was almost unless has now become deadly accurate. At 25 yards each shot is touching another. You could save the hassle by buying a new scope but if you understand what I just explained then you could save money.
High power, low weight, as quiet as you can find. Accurate when dialed in.
Scope is a pain to work with but salvageable and accurate if you threadlock the lens ring inside the scope body. Inconsistent ammo, if the lead pellet has to be forced into the barrel then don't use it (at least 1 in 10 are not a good fit), the shots will be off anyway. I am still testing out the best ammo for target shooting.

Best Gun Ever
June 7, 2013
At first the gun didn't seem to be so quiet, after about 10 rounds went through the barrel the sound dropped dramatically. Now all you can hear is the thud of the pellet hitting the target. :) IT is a Silent Stalker...... After getting it sighted in I was able to hit a dime sized target 4/5 times, however I do recommend purchasing a new scope. The scope that comes with the gun doesn't have a distance dial. As a result, the cross hairs are hard to see when fully zoomed in. The Fps is dang near what it claims to be and comes to about 1250 with supersonic ammo and 1050 with lead pellets. The gun itself has very little recoil, a SAT trigger, and is very silent using lead ammo. It is a very consistent rifle when sighted in and doesn't weigh as much as you might expect.

I want to love it.
March 18, 2013
This is a nice shooting, fairly powerful gun that I want to love, but I can't. Others talk about good accuracy but I don't see it. Maybe I'm expecting to much but at 25 yards, I expect groups to be mostly touching shots on the target. Can't quite get there with this gun. The scope is trash so I had to put more money into a new one. The trigger is not that great, but a better one can be purchased. I would rather buy quality to start with than have to fix it up after I get it.
IGT is a great improvement over springers. Shoots good, most of the time.
Bad scope. Bad trigger. Not a tack driver.

Had Accuracy Issues and Returned it
March 11, 2013
I really liked the fiber optics and the way this gun felt. It was accurate after the initial sighting in and I enjoyed shooting it for about 2 weeks. Then I couldn't hit anything I was aiming at. I actually hit the tin can next to the can I was aiming for. Re-sighted the gun, it was 6" off the target's bullseye. Thought maybe I accidentally moved the sights, so was real careful with how I handled it. Was shooting tin cans fine again, within another day or so I couldn't hit what I was aiming at. Re-sighted the gun, now 4" off the target bullseye. Took a lot of adjustment each time, was not 1 click per inch away from the bullseye, would have to move the sights 12-15 clicks. Was able to hit targets again, within another day or so could not hit the targets so I returned the gun. Airgun Depot was very good to deal with, the return was hassle free and I appreciate it.
The way it felt and the way it shot when it was on target.
Could not keep it on target. I was always re-sighting it. I could not feel the barrel moving, though it must have been.

Not bad but disappointed at first.
January 28, 2013
I couldn't wait to shoot it so I ran down to Walmart and bought a variety pack of Daisy pellets (don't laugh). I rushed home and got ready to site it in. I could not even hit the 6x6 target. I got a piece of plywood so I could tell where I was missing. My shots were all over the board. I did some research and found that the pellets make a big difference. I bought some high end Gamo pellets. Wow! The gun sounded like a 22 it was so loud. I guess the pellets were faster than sound. Finally, my pellets were grouped. I started working the site in and got to where I had a 1 inch group at about 20 yards. Finally, I have something I can work with. So there is hope and I will not return it now. Hopefully I can get good groups at 30 yards since that is about what I need for squirrels. The gun is comfortable but takes a while to zero in the technique. I could not slowly pull the trigger and found the trigger adjustment not very workable. The manual is terrible. A quick punch of the trigger was far more accurate even though this goes against the way I shoot. It is heavier than I thought it would be. There is some wobble in the hinge where it breaks and that concerns me but it does seem to center when it returns to shooting position. I am going to be careful to break it carefully to not wear the hinges out more. The scope is OK but I am sure there are better ones. I guess I am glad I got it but I wish it had a better manual. OH! It did not come with pellets even though it said they were included on the box. That would have likely increased my satisfaction because I am sure they would include pellets that shoot well in this gun.
Shoots well with quality pellets. Site works OK.
Did not come with pellets. Wobbles in the hinge where it breaks. Terrible with cheaper pellets.

Extremely happy with this rifle!
January 27, 2013
Prior to buying this rifle, I did a lot of research. Quite honestly, I got tired of hearing people complain about misc. issues with the rifle. My rifle arrived quickly and within no time at all. I had it zeroed in. For what you pay for the gun, the scope is more than adequate. It is a step up from the basic Gamo scope. My son in law has a Gamo Big Cat 1250 with a high end scope. We were target shooting side by side and my rifle was quieter and more accurate than his. I shoot JSB Diabolo Exact 8.44 domed pellets and I am very happy with them. For the money, you can't go wrong with this rifle. Especially with the IGT powerplant. Sure, you can upgrade the scope but this one is more than adequate and gets the job done. Buy this rifle!
Quiet, powerful, nice trigger pull, and accurate. Nice looking!
The thumb hole could be a challenge for people with big hands.

Not as quiet as I thought. More powerful than I expected.
January 23, 2013
Sorry that is subjective. The sound with PBA pellets are supersonic (like a small 22). If you need it to be quiet enough to keep you neighbors from being alarmed then you might look around more. Also, my thumb is almost to fat to fit through the whole in the stock. If you have fat hands check first. In spite of those points, this gun is fun!

Good looking and well balanced
December 10, 2012
Let me start by saying I have only just received it and have not yet fired it. I will update after a week or so of shooting. Out of the box it is a good looking gun. The weight and balance is excellent. The grip is really good. The sights are really nice on this and I will shoot for a while with just the sights before I try the included scope. The negative so far is that it is supposed to include some PBA platinum ammo and there was none in the box so I will need to get to my local sporting goods store and see what their selection is.

Gamo Silent Stalker Whisper IGT .177
September 2, 2012
I really like this gun. Powerful, accurate, quiet, lightweight and is easy to handle. I am right-handed, but left eye dominant, so the ambidextrous stock is a big plus. This is my second air rifle, first was a Crosman Phantom .177 break barrel that broke after a little over a year. I then bought a Remington Model 597 .22 LR to help get rid of prairie dogs in the horse pasture. But it is too noisy and the neighbors complained. So I wanted a quiet gun with a powerful kick. Using the Gamo PBA pellets lets me knock down the dogs at long range. It is quieter with heavier pellets. I look forward to getting many good years out of this rifle. I have had no issues with the rifle or stock scope. The scope is mounted tight and does not move on me. Glad I bought it.
Stock is ambidextrous large 40mm scope quality built accurate and powerful quiet with heavier pellets
Bought a Gamo Gun Buddy sling, wish it was included with the rifle

Good Rifle...Junk Scope
July 5, 2012
I shot this side by side with my older Whisper...and this rifle completely surpasses the old. Not any more accurate but the recoil pulse is super nice, and the trigger is 10 times better then the old one. Very good rifle with above average accuracy. Chronographed FPS is close to rated speed. Over 1200fps with PBA pellets, so a little loud when they break the sound barrier. Mine shoots heavy 10+gr pellets the best. A great buy for a rifle only. I had to put my own scope on it. With my 4x scope sub 2" five shot groups at 50yds is common. Easily will shoot .75" groups at 25yds. The scope is absolutely garbage so save your money on the package. Scope sucks in so many ways I could not describe them all. Buy the rifle for sure, and without the junk scope I would have rated it at a 3.5-4.
Recoil, Trigger, and FPS are superior. Rifle only recommended.

Surprising well made
March 26, 2012
This thing is NOT a toy. Haven't had it in the field but did sight it in my garage with 4 1" X 6" planks set up in layers 2 deep at just under 10 yards. Cheap pellets go through the 1st layer like it is not there and bury into the 2nd layer. My previous airgun experience is with 2 Sheridan Blue Streaks and a Crossman 22 cal target pistol. One Sheridan shot very well and the other didn't. The pistol was accurate from the git go and, after 42 years still is. My Stalker Whisperer comes up with the heft of a centerfire rifle and the scope is surprisingly nice. After I realized the recoil was moving the scope, I re-tightened the mount and it grouped of 5 that could be covered with a quarter. I shot 3 PBA platinums and grouped an inch or so higher with no other change. Waiting on the specialty pellets. When it stops raining, I'll take it outside.
Accuracy, power, economical shooting.

Great Air Rifle ever
June 29, 2011
Got mine last week, and so far about 250 rounds have been shot, excellent smoth operation, and deadly accurate on paper target 20, 40, yrds. I don't see any reason why it would'n be accurate at 50 to 100 yrds. The scope came with my machine is not 4x32 as listed on this website, it is actually the scope listed on Gomo website that actually come with the rifle and is a better scope, but I am installing a fancy scope on it anyway, to help long range target shooting, and small game later. I have used other Air rifles before, and I think this one is the most impressive is my collection machine. The stalker design is the most sharp and pretty looking concept for a modern style air rifle, but the finish costmatic on the stalker is a little too simple. The 2 stages stalk trigger is too long to pull is a known issue, so I am installing the GRT-4G trigger to make this rifle even more deadly accurate and more enjoyable to shoot. I am also dreaming about the same stalk design with C02 other power plan that strong enought for .25 - .40 cal for big game. Don't know when such a machine will be available? if Gamo take special order I will order one one now.

Great gun
May 5, 2011
The IGT system on this gun is great. I have had it for 5 months and still its delivering unbelievable power. The IGT system keeps the spring from wearing out. I bought a scope at the same time as the gun because I thought that the scope that came with the rifle would not be very good. I wasted my money on that, the scope it comes with is great. I went ahead and put on the 6-24X50 scope that i bought on it, this made the gun even better. One shot one kills on squirrels up to 70 yards. Love the gun nothing wrong with it.

Gamo Silent Stalker
November 30, -0001
I was pleased with the power and ease of operation of this air rifle. Unfortunately, I found it to be the loudest air gun I've ever owned, contrary to the advertising and the model name (Whisperer it isn't, unless you whisper like a hammer dropped on a tin roof). I also found the rear sights too small for my aging eyes and hard to get used to, though I'm now able to stay on target in the brightest light after some practice.

How heavy of pellets do you recommend for this gun, and how does the seal get ruined?

By Travis from roodhouse, Illinois on December 6, 2011
I have bought about 5 different rounds and am not really sure what i should use to hunt with. I saw where charliedatuna reccomends a pellet between 6 and 9 grains. I havent put a lot of rounds through it. I live in town and would like to have an idea of what pellet to start with so i don't run everyone out of town if I shoot a coon
By George from Stamford, CT on December 7, 2011

I just got mine about 2 days ago. So far I have used the lead superdomes which are about 8.3 grains. I like these the most compared to pointed or hollow point. The superdomes seem to have alot of stopping power. I also used the platinum pba's that came with the gun. They do travel at a faster velocity and are pretty accurate but are lighter around 6-7 grain I believe. If your hunting coons I would go with a superdome or pba for long distance or a hollowpoint for close range. The hollow points are not that accurate for long range. Good luck !!
By Conor from Sunnyside, WA on February 8, 2012

For this gun, use something between 8-11 grain light of pellets, and you will damage your piston seal.
By Carter from Washington on February 11, 2012

Try using Barracudas, Polymags, etc.
By Carter from Washington on February 15, 2012

It is better to use the heavier of the pellets, so you don't ruin your seal.

By josh from MI on June 27, 2012
What would you recommend for varmint hunting, the silent stalker whisper or the bone collector bull whisper? Also, does the silent stalker whisper .177 really shoot 1100 fps with lead pellets because found a website that said with lead pellets it really shoots at about 823 fps average.
