For the Kral Arms Puncher Mega airrifle we have a pressure regulator available that can be pushed into the pressure tube.

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.

This  model is not suitable for the Puncher NP3.

Note: No returns will be excepted on this item as it is factory set and tampering will void the warranty

The benefits of the Huma-Air, Kral Arms Puncher Mega tuning regulator are:

1.  Higher accuracy of your rifle due to the elimination of the pelletspeed fluctuations
2. A constant pellet speed over the full working pressure range.
3. It will give you a better shotcount and a full flat shotstring immediately.
4. Adding a regulator to your airrifle will probably give you the biggest benefit in the tuning process.
5. Often the rifle will make less noise due to better balance in air usage
