I'm waiting for O-rings to rebuild my leaking .25 regulator. I want to measure the reg before disassembly so I can set it back to the same pressure after the rebuild. It shoots very well at whatever it's currentIy set to. I see Huma offers a test gauge for the blank plug but it's listed for HM1000, not specifically mentioning whether it can be used for an "X" version or not.

Wika Regulator Test Gauge For RAW HM1000

Rapid Air Weapons RAW HM1000 regulator pressure test gauge Wika

I've not been able to find the exact answer with a search. Waiting on a response from Huma as well.

Anyone here know for sure? Thanks.

I inquired about the same thing. Here is the response and product I received (I haven't used it yet)

You can use the gauge on your tester, but with an adapter what needs to be modified a bit, (easy to do), and with an bonded seal it can be screwed into the action of the raw

and you need 1 oring about 9x1,5 to close the connection from the gauge to the adapter.

I can confirm this combo works in the HM1000x models (WITH the blanking plugs)

Awesome, thanks for confirming it. I've got the goods on order from Huma. Picked up one of their aftermarket regulators to play with as well.

With the HUMA reg, you don't actually need the bonded washer. That reg is shorter and the reg tester will clear it without the bonded washer. You CAN still use it, it's just not necessary as with the RAW reg.

Ah, okay. Well, I do want to measure and record the original reg pressure before I yank it out. I plan to set either it or the Huma to the same pressure when putting it back together. It is such an accurate and smooth shooting rifle, I don't feel the need to deviate. At 35 yds it flings original Heavies and the Mk II's @ 920fps in one ragged hole.

The gauge setup worked well, thanks guys.

RAW regulator was at 152b. I ended up stuffing a Huma regulator in my rifle, which was set to 141b and verified with the gauge. Fps with Heavy MkIIs was originally 920 stock. Went up to an average of 930 with the Huma. Still accurate and quiet with a Sarissa hanging off the end.

Such a great rifle to shoot!

The Huma reg is a bit smaller and allows for a slight plenum increase which is why you are seeing an increase in FPS. I had to turn my Huma down to 110bar to get my .22 18gr pellets to shoot around 920-930fps.

Okay, that makes sense. I did notice the Huma's front end does not protrude into the blanking plug area like the original reg did. Did you have to back off the hammer spring in conjustion with decreasing the regulator's pressure? I'm toying with the idea of backing off my hammer spring a tad bit to bring the fps back down to 915-920 where it was before. Just a little bit....

Degas the rifle completely. Remove the blanking plug from the bottom of the receiver block. Screw the gauge assembly into the blanking plug hole. Reinstall the bottle and read the regulator pressure.

I would recommend having at least 200b in the bottle to ensure an accurate reading of the regulator if set on the high side. I did fire several shots while observing the gauge to see how consistent the regulator was at returning to the set pressure.

Hope this helps. I'm a noob at this stuff and it was pretty easy to perform this task after researching the forum and getting the right gauge setup.

How are the Huma's adjusted.? I just pulled one out of my RAW. I seen nothing on the web site or any were else for that matter.

Mine is a HM1000x, made in USA. Plug thread is 1/4 BSP.

To be completely accurate, the thread is 1/4 BSPP (British Standard Parallel Pipe). It is not tapered as National Pipe Thread standard is in the US. I see BSP listed for fittings that are Parallel and Tapered online, so be precise on which one you choose.

On mine in the bottle end of the Huma, there is a gold or brass colored fitting, with a post and multiple air holes, that actuates the bottle valve. The fitting needs to be removed by unscrewing it with needle nose or pins etc.. Under that fitting is the regulator adjustment screw. Uses a flat tip screwdriver. Clockwise to decrease, CCW to increase.
