NEW Design for 2021, no atmosphere hole needs to be drilled in the reservoir. The regulator gets atmosphere pressure from the Bulldog's reciver end cap.
A VERY BIG SHOUT OUT!!!! To Huub at Huma Air for making us this Custom regulator made specifically for us here at Pitbull Airguns.
The regulator is adjustable from 90 to about 175bar and does an excellent job and keep the extreme spread very low. My personal Pitbull gets an average of 8 FPS spread over 2 magazines.
Please note that we do not sell these as just a regulator, they can be purchased as a kit only and even then we recommend that they only be installed by a professional airgun tuner.
We also recommend that these be installed with our longer Extended or Shroud-length reservoirs.
Kit Includes:
