The Whisper is a wonderful, lightweight, powerful air rifle. Adding the Crosman Nitro Piston conversion delivers more benefits.

You'll be ready to hunt small and medium-sized game and vermin with the Whisper + Crosman Nitro Piston. The non-removable noise dampener reduces the noise up to 52%, which means you won't spook game while hunting. Just because the Whisper is modestly priced doesn't mean you give up anything in the accuracy department! You'll be hitting your targets and making one-shot kills time after time. This just might be the ideal hunting gun!

We measured the cocking effort with the metal spring, and it was 35 lbs. (Gamo lists it at 30 lbs.). The Crosman Nitro Piston cocks with 34 lbs. of effort.

Here are the benefits of getting a Whisper with a Crosman Nitro Piston conversion:
  • Smoother cocking
  • Smoother shooting
  • No spring torque
  • No spring fatigue, even if you leave it cocked for hours
  • Functions perfectly in cold weather
  • Lasts longer than a metal spring
  • Installed by our expert gunsmiths!
  • NOTE: Installation of the Crosman Nitro Piston will delay shipment by 24 hours (or one business day)
We tested the .22 caliber Whisper with both the metal & gas springs:
Metal spring: 880 fps/PBA pellet; 739 fps/14-grain pellet
Gas spring: 960 fps/PBA pellet; 740 fps/14-grain pellet

Installation of the Crosman Nitro Piston has a 1-year warranty.

Things I liked:

Powerful, accurate, good scope.

Things I would have changed:

Shape of suppressor. The taper of the suppressor allows the cocking hand to easily slip off under cocking effort. Absolutely horrible trigger.

What others should know:

The most hideous trigger I have ever experienced on an air rifle. Spongy, with a 12 to 15 pound (measured with scale)pull, and mushy break.

Things I liked:

Lightweight, short break-in period, less hold-sensitive than my Silent Cat, quiet. Was forming 1" groups at 25 yards after only ~10 rounds with H&N Barracuda Match 5.53mm head size pellets. Pyramyd air also includes the original steel spring in the package, with is pretty cool.

Things I would have changed:

As always, ditch the Gamo scope... I guess the scope is useful as a spotter at 25 yards though.

What others should know:

Rifle actually weighs in at about 5.5 pounds, rather than the listed 5.28, probably because of the replaced spring. This most be noticeable for most people, but it can make a difference on a multi-day backpacking trip. I put a Williams 5D-GR peepsight on the rifle for maximum weight savings. I suspect the 5D-AG ( ) might fit too, since my 5D-GR is adjusted to almost its maximum height to hit the bullseye at 25 yards. Although this rifle is less hold sensitive than some other springers, it is still hold sensitive. I get best results resting the rifle in my open palm and resting my elbow on the bench, using sandbags to immobilize my elbow. I also get good results in a sitting position. I get crappy results if I rest the rifle directly on the sandbag, or even if I rest my hand on the sandbag and the rifle in my hand.

Things I liked:

I am very disappointed with the Gamo Whisper. I was unable to get a consistant shot group within 2 inches at 20 meters even afer 200 rounds. The rifle was anchored in shooting bags. I cleaned the barrel and still could not get an tight shot group. Seems as if rivets that hold the barrel in the stock might be moving providing an inconsistant aiming point. I fired expert in the US Army and have many years experience with rifles. I would not recommend the rifle to others based on my experience. I suspect I cannot return the rifle because my 30 days has elapsed.

    I purchased one 2-18-14 and it has lost nearly all of it's power. I can't dent a plastic bucket. What can I do? I only fired it maybe two dozen times.

      Is this sold with the new Gamo trigger?

      I have a Whisper that I purchased 3 or 4 years ago. Can it be fitted with the Crosman Nitro piston?

      • Val from USA answered:

        yes, pyramyd air would do it. just call them or order this crosman nitro piston and then send your rifle to them.
