Hi everyone. A few days ago, I purchased a HUMA regulator tester to check the pressure setting of the regulator in my RAW HM1000X. This rifle does not have a gauge to determine that pressure.


To my surprise, even though the HUMA website states that the RAW HM1000X regulator is compatible, it does not fit into the tester block. I also bought the HUMA 1174 regulator, and it doesn’t fit the block either.


Since my rifle is new and does not have a port to connect an external gauge, is there any way to calibrate or check the pressure of RAW HM1000X regulators? I’d appreciate it if you could share product links if available. Thanks.
 
A few years ago Air Force built RAWS were looking to extract as much plenum as practical from the design and opened up the lower chamber ( Plenum ) diameter a bit.
It created the need for a larger thread for the Reg attachment.

Marketing data is not wrong as the tester does fit all TM / BM / HM series as well all Tennessee built era "X" actions.
It is these newest AF era receivers where the problem occurs. Those of us tuning or owning these are very aware of the thread sizing issues.
* Too date have not seen a tester or a jumper / adapter to test them that one can purchase on line. ( Tho someone likely does, as this issue is several years old now :mad: )

Do you guys know the thread specs on each end? I'm just wondering if I can have fun and help people with a lathe project and if it's feasible or a bunch of tooling for me.
