Things I liked:This is the best thing that has ever happened to my gun. I got the nitro piston in my Gamo cfr and I am not regretting it. The accuracy, the cocking and the shooting have all changed dramatically in a very positive way. Things I would have changed:Nothing. What others should know:If you are wondering whether or not to buy the nitro piston buy it!! It will change everything about your gun. Things I liked:Very fast turnaround from Pyramyd. I shipped my Gamo Silent Cat on a Tuesday and received it back the following Tuesday. Kudos to them!
The gun finally feels the way that I wish it had right out of the box with this mod. Cocking is smooth and linear. Recoil is a short, not too heavy backwards push. The gun now doesnt vibrate all over the place after you pull the trigger. Also, loving the fact that I can cock and load it then leave it sitting until those pesky squirrels decide to show up to eat in my wifes garden. Things I would have changed:Not sure...yet. I've got maybe 50 pellets through it so far. As of yet, I can say that it is just as loud as it was when the spring was in place just a different sound now. If it doesn't quite down more after another 200 pellets or so then I'm going to try a recommendation to put some sound deadner in the stock. By the way, I'm not saying it is loud just not as quiet as I would ultimately like it. I can still shoot and plink in the back yard without my neighbors knowing that I am doing so. What others should know:Overall, it is a great conversion. With that said, I am a little on the fence about one aspect of the conversion though. I cannot tell if FPS has dropped or increased after the conversion. I didn't chrono the gun before I had it converted which I should have. What I am also wondering is that Gamo and Crosman are advertising guns with the Nitro Piston conversion with many different FPS ratings for guns that are shooting the same caliber. So now I'm wondering where the piston that I received falls in the FPS pecking order. With all that said, I would still do it again I think.

Things I would have changed:I wish Pyramid would allow people to do the conversion. I'm very mechanically adept with the proper tools and sending the gun away for a (admittedly brief) 10 days, killed me. I was literally tracking it twice a day. Wish the price were less overall. I hope it lasts. Pyramid should replace the plastic linkage spacer that sits on the cocking mechanism. It was worn and cocking the gun really was grinding metal until I hand fashioned a piece out of (delrin) plastic.
What others should know:If you're buying a Whisper, save the time and effort and buy a nitro-piston straight away. With shipping, etc, this upgrade cost me over 200 bucks -- 2/3 the cost of buying a NITROPISTON Whisper outright. With this piston, a GRT trigger, replaced linkage spacer, and good scope (I put a HAWKE Airmax scope on the gun) the WHISPER becomes seriously good gun. However, you COULD save money by getting the new IGT Whisper straight away. Supposedly, it has a new improved trigger and the gas ram. WIN WIN. If you already own a Whisper and are thinking about upgrading - do it, you won't be disappointed. Accurate shooting is still very determined by the hold on the gun and how you squeeze the trigger - I'm noticing that I have a tendency to pull the gun to the right slightly as I squeeze the trigger. Working on correcting that. Check shipping - UPS GROUND cost over 100 bucks from CA.!! I think USPS would be cheaper. Buy a cheap (25.00) hard plastic gun-case at a local sporting goods store for shipping. It's cheaper than paying to have it boxed and then you'll have an extra case.
