Things I liked: I guess its supposed to keep consist air

Things I would have changed: Make it more powerful I have two air cylinders for my bt65 I'd much rather have it unregulated one in the gun, my unregulated cylinder puts out around 830 fps with 44 grain my regulated one does like 720

What others should know: I love pyramid air but this was a hundred dollars wasted, wish I never bought it, don't do it thing sucks n the only reason I kept it more then 30 days is cause I was told it will kick in after so many shots,I hear air supiriority has the one, if I was pyramid air I'd discontinue

Things I liked: I like the idea.......but it just doesn't seem to be working.

Things I would have changed: size! This thing is extremely large compared to some of the other 3rd party regulators out there. Seems to take up a lot of volume in the cylinder. About 18 shots is all I can get out of a 3000 psi charge. Very difficult to remove once it's installed.

What others should know: I assumed this would deliver a more consistent air volume/pressure, thus resulting in a more reliable velocity thru out the usable range of the air cylinder. I've got over 100 shots in my BT65 with the air regulator in and still receive highly erratic shot groups. 5 Shots will be dead one, with the following 5 shots falling about 6 inches low at 40 yards. The bizarre thing is, the next 5 shots will be back on target (without filling the air cylinder)! I also had trouble initially filling the tank (with a pump) as the main seal seemed to leak air until about 500 psi were in the tank. It doesn't leak over time though. Took everything apart and re-installed. Seems to have helped the initial leak when airing up the cylinder, but still a small leak until I can get 10 or so pumps into it. Going to give it another chance at the range and see if the reliability improves. If not, it's coming out! I'd rather have a slow, steady drop in velocity/range rather than erratic changes.

  • Rune from USA asked:

    Hi. I have a 17 joule Hatsan bt65 . 22 that I would like to restore the full power to. What do I need to do get it restored to full power?

    • Mark from USA:

      You would have to have the gun serviced thru Hatsan USA. They have their own service center and the parts.

  • Roger from USA asked:

    Will this fit a new model gladius. 25? Also how can you tell if you have a new model verses an old model?

    • Mark from USA:

      The Hatsan made regulator has been discontinued. To get a refulator you will have to get an aftermarket model . Huma,Lane,or Altaross.
