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.

Hola a todos, disculpen que escriba en español, soy Roberto de Argentina, el tema es que no hablo ingles y utilizo el traductor para poder leer los hillos que publican. Tengo un Raw Hm 1000 X cal. 5,5 que modifique bastaste y uno de los problemas que he tenido era el de poder comprobar a cuantos bar estaba regulada la valvula, como todos saben y ya lo han comentado este rifle no trae manometro de la reguladora y en las versiones mas modernas la fabrica los hace sin el orificio en donde se puede enroscar el manometro que vende HUMA. Yo he tenido que mandarme hacer un probador de valvula independiente. Regula la valvula fuera del rifle a la cantidad de Bar que deseo y luego se lo instqalo en el rifle, es la única solución que he podido encontrar. Voy a ver si les puedo subir las fotos.
Sin embargo y como el tema es muy complicado elegi, colocarle una valvula reguladora con seteo externo donde tengo los dos manometros uno que indica el aire en el deposito y otro la cantidad de Bar seteados, con la facilidad de apretar y aflojar un tornillo para subir o bajar la presión. espero que sirva de ayuda

I'm working on this transitional martin/airforce gun. I see the ordeal with measuring reg pressure and may need to build a test mule fixture for this regulator setup or a guage adapter.

At first I was frustrated with the layout of the gun and the design principles being rather alien to me being a crosman group, fx, aea guy already. Once I "got in Martin's head" and could see why he designed the way he did it makes a lot more sense to me. My best description was this is a boutique gun. You don't change the oil on your Bugatti in the garage, you send it to Bugatti to be done and that the curated environment/experience vibe I get from this gun. I don't think anything but hammer spring tension was Intended to be touched by the end user.

That said, I may machine something to address the issue. If I do and it works correctly I will post on agn and see if anybody wants one made for them too. I'm leaning towards an off-the-gun sort of deal so you can adjust it.

Good luck everybody else, these guns are very interesting.
