This Huma-Air regulator is placed inside the pressure tube and stands on the valve house body. The original regulator is bridged so it had no more influence on the shooting behaviour.
It 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.
The benefits of the Huma-Air,Artemis PP700 tuning regulator are:
Higher accuracy of your pisTol due to the elimination of the pelletspeed fluctuations
A constant pellet speed over the full working pressure range.
Designed for a wide pressure range 85-150 bar
Easy to adjust without the need of a regulator tester because of the clear pressure scale on the regulator
