Things I liked:

Much more consistent shooting. Gives a solid TWAP ! instead of the TWANGG! i am used to in my Gamo Whisper. I feel like the torque/twisting/vibration of the springer is gone completely and my accuracy and confidence of hitting small targets has gone up considerably.

Things I would have changed:

Include basic instructions for those not choosing to have this installed by Pyramyd - Possibly a centering socket/bushing to contain the ram ?

What others should know:

I did not find a LOT of information online about how to install the ram - but there is enough out there if you have any experience disassembling your airgun. Use a large clamp or spring compressor for sure. I am a do-it-yourselfer and the cost of shipping/being away from my baby for a week was not worth having Pyramyd do the work. I did not like the fact the smaller 1/4"rod end of the ram directly impinges on the gun piston with no centering washer/bushing or anything between the rod and piston like the old spring had. I suppose it is fairly stable because the gas ram body is centered in the spring tube, but it felt like there was room for improvement in the overall design of this retrofit. I will disassemble at a later date to inspect the gun piston for any damage, so far there is no indication anything is wrong. Overall - I'm extremely happy with the results of the conversion and wish i had done it long ago. As a bonus I still have the old spring if/when the gas ram ever fails !

Things I liked:

I had this installed into my older Gamo Viper. This piston exceeded my expectations. I have another Gamo with their IGT system and the Crossman Nitro blows it away. My rifle sounds like a .22 and has awesome power. I may send my other rifle in and have it changed to the Nitro piston.

Things I would have changed:

Nothing

Things I liked:

No spring rattle when fired, but seemingly sharper report. Maybe because of no rattle.

I'm happy
