Things I liked: I have had my Falcon Hunter for about two years and I like the power that it has. I have dropped crows @ 100yds with it. I decided to go have the Nitro Piston installed because it was supposed to be easier pull and smoother action. It is all true the gun acts more like a regular rifle now with the recoil going straight back as apossed to pulling. I will admit after using this rifle with the spring for so long it takes a little getting used to. It is quieter, smoother, and hits just as hard as the spring in my opinion.
Things I would have changed: So far it works well. I wouldn't change anything
