Things I liked: Much improved accuracy, by taking away the recoil characteristics of a metal spring. Able to keep NP powered rifle cocked for extended period of time without possible damage or fatigue of piston. Good power, although possible loss of fps with conversion, but very little at that.

Things I would have changed: The Nitro Piston is not a bad piece of kit. I would like to see if Pyramydair will offer the Hatsan Vortex in the near future. There is really nothing I can think of at the top of my head on what needs changing.

What others should know: I had this installed in my Hatsan 125Th, in .177, and it is like shooting an entirely new beast. The shooting of my rifle took much practice and a consistent hold when the metal spring was installed, but with the NP hold placement is much less sensitive. Accuracy is very much improved.

Things I liked: I replaced the springer in my Walther Falcon Hunter and what a difference it makes. Easer to shoot and more accurate even with open sites. Pyramyd Air made it very easy to get it installed and returned to me. Thank you Pyramyd Air for your great service and technicians.

Things I would have changed: Make them for more air guns.

Things I liked: Nothing! I bought a WFH 22 cal that had this upgrade done to it by PA. These guns are supposed to shoot in the 900 fps range with 14.3 pellets. Mine shoots 750 fps way too slow. This is what my Trail NP shoots and it probably had the same piston installed intop the WFH. Not what it should be. Don't do it.

What others should know: Find some of the new NPistons... by Moller and N Forcer have one of those put in.

  • Wayne from USA asked:

    I recently bought a Benjamin steel Eagle, thinking the advertised under 500 fps was a misprint ,it was a correct assessment!, This rifle couldn't penetrate a couch cushion at 12 ft. Anyways i was wondering if anyone could tell me which gas ram is compatible with this rifle, or if the piston has air holes punched to reduce power?. The rifle is ,22 cal. I would like to keep it if there's a fix

    • Mark from USA:

      We do not have a gas piston that fits the Steel Eagle. For a replacement contact Crosman.

  • Ed from USA asked:

    I was wondering if this crosman spring Piston would work in a Crosman Phantom originally equipped with a steel spring, I'm looking to use it as a conversion, to greatly reduced or eliminate the double recoil effect so commonly known to plague steel springers, and help increase accuracy. If so, what power loss or increase could be expected from this conversion. I'm not certain but I believe this Crosman Phantom was advertised as a 1200 fps .177 cal. I would like to convert the Phantom into a NP powered rifle, because I own the Crosman Titan GP which is NP powered and it's much smoother, more accurate, and is plenty powerful, but with the wooden furniture or (stock) the Titan is not as durable in rough terrain, I enjoy using these air guns for squirrel and rabbit hunting, it's more of challenge to hunt with a rifle than to use a shotgun, using an air rifle makes it that much more difficult which I consider more sporting. Thanks in advance, an avid airgunner.
