Things I liked: Great item ahipping fasr came on time wrks great with my hun which is a crosman thrasher 22 it more powerful will recommend to buy and will buy again for sure
Things I would have changed: Non
What others should know: Non
Things I liked: Installed this on an original Benjamin nitro piston synthetic stock air rifle along with a new seal. Used super lube 100% silicone lube for the seal. Great improvement over the stock gas spring. I baked on a Teflon/moly epoxy coat on the piston that the seal is installed on. This coating is self lubricating due to the Teflon moly. Super lube worked well with the seal, although it is thick like honey (doesn't take much). Rifle absolutely loves the H & N copper spitzkugel very accurate out to 50 yards if the wind isn't blowing. Overall very satisfied with pyramid air. Had only 1 complaint.
Things I would have changed: None
What others should know: If you buy the cr piston for the plain Benjamin nitro trail. The piston rod is larger than the original and will not fit in the machined recess for the piston. (Original was machined to a smaller diameter to mate in the piston recess). My solution was to grind down the 1st 3/8" to more of a point to fit in the machined recess. My piston rod fits tight in the recess and I haven't had any problems. One thing I did to accurize my Benjamin was to recrown the barrel with a brass screw and automotive valve grinding compound. Made big difference in accuracy, factory crown wasn't done well.
Things I liked: Easy to change and seems better than the original. Will be interesting to see how long it last (the factory one did not last very well). Price is a little steep.
Things I would have changed: Lower the cost

Hi does it work in a crosman shockwave nitro piston and does it have all the seals
Yes It will work.We do not have any instructions.
On the shaft (the black part) of the original BT5M22-00-1A, there is a metal o-ring which I guess is necessary in order to maintain a constant gap between the piston and the gas spring. However, this o-ring is not apparent in the picture of the advertised CR Nitro Piston. Any explanation for that?
For that information ciontact Crosman.
I do have the Crosman F11 in .22, canadian 495 fps max version. The rifle comes with the BT5M22-00-1A gaz spring and a 190 mm piston (there is no hole in it). If I ONLY replace the gas spring, what can I realistically expect in terms of fps with standard 14gr pellets?
If the upgraded piston fits, You will get 750-800 FPS.
