On Gun Unireg Question

[Alan Smith]

Hi,

Thanks for the messages! This has moved along as I’ve found an on gun Unireg (pictured). The raptor manual suggested above is a good reference, the main difference between it and the Unireg looks to be the gas distribution body, the reg components look the same (3k version not the Rex) and also look to be the same as the mag AIR valve.

Can anyone confirm the mag AIR valve, Unireg and Raptor 3k share springpack, piston, reg seat and reg pin?

This would also mean the raptor manual quoted output range of 200-1000 psi would apply to each reg?

The reg distribution body on the "on gun Unireg" has two threaded inputs one from the bottom line asa and the other was used for a fill nipple. So the original setup was an air bottle with brass on/off valve feeding 3k bottle pressure through to the Unireg grip and filling was done from the reg. The one I have pictured came like that and I’ve found a friend has two set up like this with hard lines (3k rated?) running between the reg and bottom line. Any advice on 3K rated hard lines would be appreciated?

From the feedback above I think it may be possible to source a new brass valve with 5k burst disk suitable to go on a modern 3k hpa bottle. The system wouldn't have a 1.8k burst disk but I was thinking this could be fitted to the vertical asa above the reg?

Last question the reg pictured has two outside orings on the distribution body, I read this was for a tournament lock cover, does anyone have a picture of one of these?

Thanks again,

I remember a couple of them would fill their tanks partially with compressed air (by plugging into the input of the on gun reg)... then they would unscrew their tank and put some CO2 in it (which to me was silly)... they would do it to get more shots...

Yeah, the old CO2/HPA cocktail.

For those that don't know the reason. As long as the compressed air pressure in the tank remained above 850psi due to volume, the CO2 remained in a liquid state and the gun would run on compressed air. As the air pressure fell below the pressure required to keep the CO2 liquid, the CO2 would release to a gas state at about 850psi until the liquid was gone. This allowed the user to essentially utilize the entire volume of compressed air at a pressure of at least 850psi and then the gas would gradually become CO2, instead of losing pressure once 70% of the 3000psi tank was used.
