Things I liked: I had Pyramyd install the nitro piston in my Gamo Silent Cat. I like that it's easier to cock and there is still some recoil but not as bad as the mainspring. The power on my my shots seems to be slightly less but the accuracy of the rifle has improved due to the consistency of power using the nitro piston!
Things I would have changed: Absolutely nothing!
What others should know: The rifle seems to warm up around the area where the piston is installed;however, this non issue has not affected the performance of my rifle. I wish I had it installed sooner it's worth it!
Things I liked: At the moment there isn't anything I like, as mine practically exploded on me.
Things I would have changed: Specific fitment charts for gamos so you know you aren't going to have issues.
What others should know: Be as sure as possible that this will fit and do as I did and have some test fires with the gun securely strapped down and pull the trigger from a distant with a rope or string. I am glad I did this, even though it did bust through the outer shell of the air rifle, it did fail on me internally and then when my gunsmith was disassembling the air rifle it exploded out the back.
Things I liked: Repeatable power. Reliable. No spring variables or noises.
Things I would have changed: Nothing
What others should know: Service was excellent. I purchased the item through the website, included a comment stating that I would be sending in my gun for free installation and it was a same day turnaround when they received the gun.
Will it work with the Gamo Shadow Express?
Can this be used to replace the piston in a Crossman NPSS ?
