Things I liked:Had my Gamo Whisper Cat converted to the Nitro Piston. Dramatically reduced the noise from the original spring, the spring was painful to the ears without ear protection, still wear ear protection when shooting with the NP installed. Operation is smoother, seems to have more power and accuracy is up with various bullet weights.
Things I would have changed:Nothing
What others should know:If you have a spring powered air rifle this will fit, get it converted, it is worth it.

Things I liked:everything! i had the conversion done to my gamo whisper dx after the spring broke and i am so happy i did. Not only did it make my gun a true whisper it increased power, fps, and overall performance of my gun.
Things I would have changed:nothing!
What others should know:it made my gun so quiet that i can shoot it and a person on the other side of a wall will have no idea i shot. If u shoot and hunt with your airgun a lot like me then this is a must have for you!
