Things I liked:

This piston fits many different rifles . It is quieter than a metal spring , and generates way less recoil . It' also less damaging to scopes .

Things I would have changed:

The only change is this - Quit producing "springer" air guns and make only "gasser" air guns (nitro piston) .

What others should know:

I own two air rifles with this piston already installed . Crossman F4 .177 ,and a Benjamin prowler .22 . I can't believe the difference in noise and recoil compared to my Gamo shadow whisper . I plan on buying one of these pistons and installing it in my Gamo . There are many tutorials on Youtube showing step by step how to install these pistons . The only special tools needed is a bar clamp to compress the spring or piston assembly to remove or replace the pin during disassembly and assembly .

Things I liked:

I ordered the nitro piston on 03/21/2017 and received it on 03/27/2017, Great FREE Shipping! I installed it the same day, and ran into a problem, my trigger would not fire ! I thought I had the wrong piston for my rifle, so i called PyramydAir, unfortunately i had to leave a message, but they did call back the next day to let me know that i had the right piston. I fixed the problem { i had put too much pressure on the piston with a washer causing the trigger group to lockup}. After removing the washer the rifle shoots GREAT!!! Much more power and accuracy, and i thought the spring unit was good, WOW !!! Thanks PyramydAir ,

Things I would have changed:

Nothing !

What others should know:

Watch the instructional videos and follow them to the T. Trying to re-invent the wheel can cause catastrophic problems.
