Kral Arms Puncher NP-03 Huma-Air Tuning Regulator
For the Kral Puncher NP-03 we have a tuning regulator available that will boost your air rifle's performance to the highest shot consistency and best accuracy.
This regulator is vented to the atmosphere without any modification to your pressure tube. So no drilling in the tube and also no creeping up in power during time.
It will only fit the NP-03 versions.
