The Air-powered Kinetic Canine


The Pitbull AKC was created in response to Bulldog owners that wanted a regulated rifle with a larger capacity reservoir and the option of using cylindrical moderators such as the DonnyFL. 

The length of the Bulldog remains the same as stock, with the addition our 4500 psi "BlueTick" shroud-length HUMA regulated reservoir. The HUMA regulator is set to 2700 psi, and with a 4500 psi fill, you can expect  up to 6 regulated shots ( MORE IN 257 CALIBER) for super accurate big game and varmint hunting.  The average muzzle energy is 220 Ft/Lbs (357 CALIBER)  with 160 grain ammo and 215 Ft/Lbs with 142 grain ammo. The installed HUMA Regulator removes the nasty Bulldog "banjo ping" so there's no need for a DePinger. 


The front of the reservoir has the Airbow end cap and a 5000 psi gauge. a Fill Probe is included. The original Bulldog gauge on the side of the rifle becomes the regulated pressure indicator.

Triggers Explained:


  • Hunter Style:
    Slightly heavier first stage, super smooth but slightly longer second stage travel and a very crisp let off (or break). Accuracy and hunter safety in the field are top priorities.


  • Competition Trigger:
    Shorter and lighter first stage travel with a smooth Sear Link roll-off to the shorter second stage combined with a very crisp let-off from the Sear Hammer. Careful adjustments to the Sear Spring make for a light trigger weight.
  • Sportsman:
    Split the difference between the Hunter Style and Competition Trigger, and you have the Sportsman. Adjustments are made to the Sear Spring, Lower Sear and Sear Hammer giving you the best combination of both, whether in the field or at the bench.
