This report covers:
• Summary of the AirForce Escape report up to this point.
• There are three different air rifles.
• EscapeSS is quieter.
• EscapeSS description.
• How does the EscapeSS differ from the TalonP pistol?
• What comes next?
It’s been a while since we last looked at the AirForce Escape air rifles. To date, we’ve seen the power, accuracy and general characteristics of the AirForce Escape and the EscapeUL, which is the ultra-light version. Today, we’ll start looking at the EscapeSS, which is the version of the rifle with some sound muting.
We’ve seen that the Escape rifles can generate tremendous power — up to 97.88 foot-pounds of muzzle energy from the Escape rifle when the heaviest .25-caliber pellets are used. We’ve also learned that the Escape rifles are at their most accurate when the fill pressure is lowered and the power is dialed back. That held true for both the Escape and the EscapeUL, so it seems to be a trend; and I’ll use that experience when testing the EscapeSS.
There are three rifles!
Before moving on, I want to emphasize there are three different air rifles. The Escape, EscapeUL and EscapeSS all have different specifications and deliver different performance. I’m telling you this because customers are starting to run the model names together and getting confused over which rifle does what.
Each of these air rifles is unique and different from the others. The Escape is the most powerful of the bunch. The EscapeUL is the smallest and lightest, and the EscapeSS that we’re looking at today is the quietest of the three.
If you forget how the first two rifles performed, I urge you to go back to the reports linked above and catch up. I intend reporting on just one rifle in this report — the EscapeSS.
To achieve this quieter report, the EscapeSS has three baffles ahead of its muzzle. They’re held tight in the frame by a Belleville washer ahead of the last baffle and behind the end cap.
I’ve already been to the range and can report that the EscapeSS really is quieter than either the Escape or the EscapeUL. It has the same recoil of the other two, which is greater than the recoil of a medium-weight .22 rimfire rifle, but the sound is greatly reduced.
However — just because the muzzle report is greatly reduced from the Escape does not mean the EscapeSS is a quiet rifle. While it’s much quieter outdoors than a .22 rimfire, it’s also louder than a Benjamin 392 pumped 8 times. The EscapeSS is not for suburban backyards! It’s more of a quieter hunting air rifle for public lands. I doubt it would be noticed beyond a half-mile away.
The EscapeSS description
The EscapeSS is a precharged pneumatic air rifle that comes in both .22 and .25 calibers. It has a 12-inch Lothar Walther barrel; but like all AirForce sporting rifles, it can accept barrels of any length. It can also accept other calibers, but I don’t believe I’d try one in .177 caliber because this powerplant is so overwhelmingly powerful that it would be hamstrung by such a small bore size.
The rifle weighs 4.3 lbs., and its length varies from 27.75-inches to 32.25-inches — depending on how the shoulder stock is adjusted.
The rifle is made on an aircraft aluminum frame that houses all the parts, including the barrel. The 213cc air reservoir can be filled to 3,000 psi, nominally giving about 10 powerful shots. Like all AirForce sporting air rifles, the EscapeSS has adjustable power via an adjustment wheel located on the left side of the frame.
How does the EscapeSS differ from the TalonP pistol?
I have to address this issue before the questions start flooding in. Sharp observation will notice that both the EscapeSS and the TalonP have the same 12-inch barrel (that comes in both .22 and .25 calibers), and they share the identical powerplants. So, what makes them different?
First, the TalonP frame is shorter. This makes the gun smaller, but it also means there’s no room for the baffles. The TalonP is louder than the EscapeSS at the same power.
Next, the TalonP comes without the extendable shoulder stock. You can purchase one as an accessory if you like, but the basic pistol comes without it. The EscapeSS is a rifle that comes standard with the shoulder stock.
The EscapeSS and TalonP should both develop comparable power when they’re set up the same way. But the TalonP is more compact, and the EscapeSS is more of a carbine-length rifle. You have to decide which is best for you. You can always add the shoulder stock to a TalonP, but you cannot make it as quiet as an EscapeSS.
As I said, I’ve already been to the range with the EscapeSS. I used the experience obtained when testing both the Escape and EscapeUL rifles instead of testing every pellet in the rifle. And I knew beforehand that the fill pressure and power settings needed to be lowered, so I started low and worked around until I found the best combination.
We know that the EscapeSS has a 12-inch barrel. Knowing how barrel length affects velocity, we know that the velocities for this rifle are going to be lower than for either of the other 2 rifles. But when I tested the rifle, I discovered something I didn’t expect.
All these tests used the 43.3-grain Eun Jin pointed pellet. On high power with a 3,000 psi fill, the first 5 shots gave the following results.
This gives an average of 763 f.p.s for the first 5 shots. At the end of the shooting, the tank pressure still read 2,500 psi. At the top velocity (shot 1), this pellet produces 59.26 foot-pounds of muzzle energy. At the average velocity, this pellet produces 55.99 foot-pounds.
I then dialed the power setting to 8 and refilled the tank to 3,000 psi. That gave the following results.
That gives us an average velocity of 756 f.p.s. Not very different, is it? The tank pressure after these 5 shots read 2,400 psi. At the top velocity, the muzzle energy was 59.11 foot-pounds. At the average velocity, the energy was 54.97 foot-pounds.
Then, I dialed down the power to 4 and got a huge surprise. That gave the following results.
The average velocity for this string was 769 f.p.s. — the highest in the test! At the top velocity, this pellet produced 61.70 foot-pounds of muzzle energy. At the average velocity, it made 56.87 foot-pounds! So, the rifle was more powerful on power setting 4 than it was with the power wheel dialed up as high as it will go. The rifle’s ending tank pressure read 2,500 psi.
The 12-inch barrel is showing up in these results. Clearly the rifle is wasting air with this pellet when the power is set above a certain low number. I think the number is around 4, but it would take more testing to know for sure.
That’s as much velocity testing as I’m going to do now because it isn’t helpful. I’ll come back and do a more thorough velocity test when I know which pellets this gun likes. With this gun, it isn’t just about power. Accuracy is also very important. The best combination of both is what we’re looking for.
In my next report, I’ll show you the results of the first accuracy test, which are very encouraging.
The next step in testing the Escape rifles
After we complete testing the EscapeSS rifle for accuracy, we’ll start the next phase of testing for all 3 rifles. That will be testing their velocity at the most accurate setting with the most accurate pellet or pellets.
Following that, I’ll install a .22-caliber barrel in the Escape and test that. If I see enough difference between the Escape and the Condor, we may do more testing in that caliber, but I don’t know yet. It’s too far into the future to know for sure.

Today will be a very interesting report, in my opinion. The Gamo Whisper Fusion IGT air rifle I’m testing turns out to be a fascinating airgun in many ways. Let’s get right to the report.
Today we will look at accuracy at 25 yards with the scoped rifle. The first thing I had to do, therefore, was mount the scope. The rifle came with a scope installed in a one-piece scope mount. Its vertical scope stop pin was already correctly adjusted to fit the stop pin hole in the raised mount on top of the rifle’s spring tube. That is rare, in my experience. Normally, the scope will be installed correctly in the mount but has to be taken out of the mount to sufficiently adjust the height of the stop pin.
I’d used this mount for my report on shimming scope rings, so I did remove the scope from the rings after all. Following that report, I left in the one shim that was shown in the report. The mount Gamo included with the test rifle has four screws per cap and seems to be a good one. It’s a one-piece design that does limit the positioning of the scope, but I was able to locate it fine for my use.
The adjustable cheekpiece helped a lot. I had it adjusted up to almost the top position, and my eye lined up with the rear of the scope with no unnatural repositioning of my head.
Surprise No. 2 was the scope. I initially sight-in at 12 feet to get the shots safely on paper, and inexpensive scopes are usually very blurry this close to the target — even if they’re set on low power. This rifle comes with a very nice Gamo 3-9X40 scope that was quite clear on 3x at 12 feet. Back up to 25 yards and boost the power to 9x, and the glass remains very clear. It’s been a long time since I liked a scope that came bundled with a gun as much as this.
The Smooth Action Trigger (SAT)
Next, I must comment on Gamo’s new SAT. It’s a 2-stage unit that has a light first stage and a second stage that you can feel as you continue to pull. The trigger blade moves through stage 2 smoothly and breaks cleanly, but not with the sudden glass-rod crispness we talk about all the time. Instead, the feel is one of movement that is predictable and can be controlled. It isn’t bad — it’s just different from other triggers.
I reported in Part 2 that the trigger breaks at 3 lbs., 12 oz. That may sound high if you read about PCP triggers breaking at less than a pound, but it really isn’t that bad. The thing to do is experience it for yourself before you judge it. I find it to be manageable and not at all troublesome to the best accuracy.
The light weight of the rifle, on the other hand, does present something of a problem. This rifle is so light that even when the off hand touches the triggerguard, the rifle still has neutral balance. It floats in your hand. That makes it difficult to hold on the target because the crosshairs want to dance around. The solution is a very light artillery hold that does benefit the rifle’s accuracy, and I’ll address that in a moment.
Normally, this is where I launch into the accuracy test and start making comments about the groups. This time, I have more to say, and it isn’t just about the groups — except how they helped my understand the rifle in a diagnostic way.
JSB Exact RS
The first pellet tested was the JSB Exact RS that did so well in the 10-meter accuracy test with open sights. I knew from that test that these pellets like to be seated flush with the breech for best results.
As I shot these pellets, I saw a strange phenomenon unfold. The first 3 shots were out of the bull at 5 o’clock. Then, I relaxed very consciously and allowed the rifle to float on my off hand. The next several shots went into the black. On shot 8, I didn’t relax like I should have, and I threw 1 more shot out of the bull at 5 o’clock with the first 3. How interesting!
It was so interesting, in fact, that I shot a 14-shot group, so that 10 of the shots could be fired with me being very relaxed. When you look at where they landed, you can see that the hold was all-important to where this rifle grouped.
Now that I knew something about how the rifle performed, I figured I could do a lot better. And the very next group confirmed that.
H&N Barcuda Match
Next up were the H&N Baracuda Match pellets that shot second-best in the 10-meter accuracy test. Now that I knew how to hold the rifle, I expected to see a better group. And that’s exactly what happened.
I adjusted the scope after finishing the first group, moving it a few clicks to the left. The first Baracuda Match landed at 11 o’clock, just outside the bull. Shot No. 2 hit at 8 o’clock outside the bull. I was obviously holding the rifle too tight, so I made a conscious effort to hold it looser and shots 3 through 7 hit inside the black. Then, I tensed up again, sending shot No. 8 into the same hole as shot 2. The final 2 shots were fired with complete relaxation, and I had a respectable group inside the bull to the left of center.
This time, there were only 3 shots that missed the main group, and all of them were fired with some tension in the hold. When I relaxed, I was able to put 7 shots into 0.789 inches. I think this represents the true accuracy potential of the rifle. Total group measures 1.995 inches.
Altering the hold
Now that I understood the rifle better, I decided to move my open palm out farther so I could feel the cocking slot. Sometimes, resting the rifle this far forward is better. It certainly makes it more stable.
This time, however, there was no improvement. The group opened up, and I could see no way of controlling where the shots went. The total group measures 1.754 inches between centers, which is tighter than the previous group overall; but there’s no tighter group within this group that tells me the rifle wanted to do any better. Although this is a smaller group, I think the previous group that was shot with the off hand touching the triggerguard shows more promise. So, I went back to the other hold for the next group.
Two pellets I didn’t try were RWS Superdomes and Gamo Raptor PBA. Both had done so poorly in the 10-meter test that I felt it wasn’t worth the time to try them again at 25 yards. That’s one of the benefits of 10-meter testing — it eliminates some pellets.
But I wanted to try at least one more pellet, so I selected 7.9-grain Crosman Premier domes, simply because they’re often very accurate in spring guns.
I now knew the best hold for the rifle, so all I had to do was hold it as loosely as possible and let the pellets do the rest. Nine of the 10 pellets went into a nice group measuring 0.845 inches between centers. It was the first shot that opened it up to 1.596 inches.
I find it interesting that the early shots were always thrown wide of the main group. By the time I arrived at the third pellet, I managed to keep the wide shots to 1 in 10. That tells me something. It tells me that the Gamo Whisper Fusion IGT is a rifle that has to be learned. Once you’ve done so, I believe that your groups will be about the same size as the smaller groups seen here.
I’m going to say something that may surprise some of you. I really like this air rifle a lot. I think it is too light and the trigger takes some getting used to, but in the end this is a great budget air rifle. It really isn’t that fussy, once you learn how to hold it the right way.
For some of you, even a used Beeman R9 is too expensive. I think you may want to look at the Whisper Fusion IGT. This is a gas-spring air rifle that has not gone overboard in the power department. It has a usable trigger, and it’s reasonably quiet and accurate. No, it isn’t as accurate as an R9, nor is the SAT as nice as a Rekord trigger; but for those who want to cap their outlay for an air rifle at $260 with a scope included, I think this is the one.

This is the first accuracy report for the .177-caliber Gamo Whisper Fusion IGT air rifle. I shot this test using the open sights at 10 meters from a rest. I did that because I usually don’t have much luck with powerful gas-spring air rifles. They tend to spray their pellets all over the place. And getting a scope mounted and stable can also be a problem, so I wanted a track record for the rifle before I got to any of that.
Smooth Action Trigger
I usually wait until the accuracy test to report on how well the trigger, which in this instance is the Smooth Action Trigger (SAT), performs. The pull weight, measured in part 2, releases at 3 lbs., 12 oz. It’s a 2-stage trigger with a second stage that needs some explanation. Instead of pausing at stage 2 and then breaking cleanly, the trigger on the test rifle — and I must assume on all SAT — pulls through stage 2. You can feel the trigger move, yet there’s no creep. The pull is — well — smooth! And it’s predictable. It’s a different sort of feel from other triggers but not different in a bad way. I don’t think anyone will need to buy an aftermarket trigger when they have a rifle with the SAT installed. Well done, Gamo!
I also thank Gamo for making the safety manual. It does not come on when the rifle is cocked. That makes the shooting progress that much faster and with less for the shooter to do. It’s a small thing, but one that I noticed and must comment on it.
Feel of the rifle
This is a very light air rifle, yet the stock is shaped so your off hand goes to a spot immediately in front of the triggerguard. The rifle is so light that this still gives it a neutral balance, but it hangs right in the hands and feels good on the shoulder. The more-vertical pistol grip has something to do with the good feel, as well.
I did find the stock stinging my cheek with each shot, however. It served as a reminder to hold the rifle even lighter than I was, which is a good thing. Once I did that, there was no more stinging.
I sighted-in the rifle with JSB Exact RS pellets and discovered that the front sight was too high for a 6 o’clock hold on the 10-meter pistol bullseye target I was using. So, I did something I’ve never before tried. I’ll illustrate the sight picture I used.
As you can see, I placed the front bead at the top inside of the bullseye. The bull was so well lit that the bead showed up as black on gray. Maybe this isn’t the best open sight picture, but it seemed to work well enough for this test.
JSB Exact RS
The first pellet I tried was the JSB Exact RS dome. We know it’s often a good pellet — especially in lower-powered air rifles, which the Fusion IGT certainly is not. In this gun, the RS develops 14.32 foot-pounds, which puts it into the medium power group. If you’re a hunter, that’s where you want to be, so long as the rifle is also accurate.
The RS pellet put 10 shots into a nice round group that measured 0.591 inches between centers. While that isn’t a spectacular 10-meter group, it’s good when you consider the novel sight picture I was using. I’ll keep the RS in mind when I back up to 25 yards and mount a scope.
The next pellet I tried was the RWS Superdome. This pellet generates 15.43 foot-pounds of muzzle energy. Ten shots made a group measuring 1.332 inches. But it’s the shape of the group that’s really interesting! Five of the pellets landed in a very vertical group, while the other 5 made a beautiful small round group of their own. This target demonstrates why 10-shot groups are better than 5-shot groups because many shooters would just accept those 5 close shots and be done with it. I don’t think the Superdomes are right for this rifle based on all 10 shots.
H&N Baracuda Match
Many shooters think that heavy pellets are bad for spring guns. They’re supposed to damage the coiled steel mainspring. I wonder what they do to a gas spring like this IGT? That’s my way of saying I don’t think pellet weight is that much of a problem in a springer. Baracuda Match pellets average 824 f.p.s., for 16.06 foot-pounds of muzzle energy. Impressive power. If they’re also accurate, this will be a good pellet for the rifle.
And, accurate they are! Ten H&N Baracuda Match pellets went into 0.625 inches at 10 meters. That’s a pretty impressive group, considering the strange sight picture I’m using. It’s only slightly larger than the JSB Exact RS group, and I think these pellets have earned a spot in the 25-yard test, as well. I have no idea of why they’re spread out horizontally. When I checked the stock screws, all were tight.
Gamo Raptor PBA
The last pellet I tested was the Gamo Raptor PBA that Gamo uses to get the velocity out of this powerplant. Raptors go an average 1,232 f.p.s. and produce 18.2 foot-pounds of muzzle energy. That’s the best performance I saw from this rifle…alas, they aren’t accurate. Ten made a groups measuring 1.118 inches at 10 meters.
PBA pellets also cracked like .22 long rifle rounds because they broke the sound barrier. The noise, alone, would keep me from shooting them.
Evaluation so far
This rifle has plenty of good in its favor. The hold is good, the cocking is light for the power and the trigger is very nice. I’ll withhold my final opinion until I see how it does at 25 yards; but if this was any indication, this could be a best buy.
