These popular pellet guns are a lot of fun.

Maybe your pumper needs a Pump RP valve, a more powerful hammer spring and a larger transfer port bushing to wake it up a bit.

  • This listing is for one (1) of our Pump RP performance valves, one (1) Power Hammer Spring AND one (1) of our Boss +25% transfer port bushings... allfor the Crosman pumper guns listed above
  • Our very popular and proven Pump RP valve will allow for more power at pumps beyond 10. It is \"plug and play\" so does not require a flat top or adjustable piston.
  • This hammer spring will drive the hammer harder into the valve to help keep it open longer for an increased blast of air.
  • The Boss +25% will give that larger blast more of a highway from the valve to the barrel port.
  • These proven performance parts are freshly new (not old stock) and have never been used.
  • These parts are completely ready for you to install into your Crosman pump air gun (see above).

With every order, I will ship same day or the next business day.

Your order will have a tracking number as well.

Feel free to email me any questions you may have.

Please offer confidently.

Excellent customer service has always been my most important goal.

My response backs that up (and will continue to).
