Mystery Edgun regulator

[JakeRico]

Can anyone confirm if this is a Edgun brand regulator and Plenum? Have any of you seen this in your R5M?
Maybe Ed will chime in.
Here’s a Photo comparison of the Edgun and the Huma below , also the valve housing doesn’t have a bleed screw

Here's what the factory valve block, regulator, and plenum spacer look like in my 2019 R5M. Neither of the regulators in your photo look like mine. I'm fairly sure that the bottom one in your photo is a Huma, having the tape scale with pressure markings. The upper one may be an older or newer design. The plenum spacers are very different. Your bottom one matches my factory spacer.

The bleed screw in the valve block is on the bottom surface that faces down when it's installed. It takes a tiny two or 2.5 mm hex. Attached is a diagram from the schematic for the valve block showing the bleed screw (item 5) and ball (item 4).

That is either a HUMA or a Robert Lane regulator

Thank You Feinwerk and Woogie man
You’re both correct the bottom one is a Huma and the top one is from what I’m told is Edgun‘s last version for the R5M.

@JakeRico ,
Interesting. If that is a new regulator and plenum design for the R5M (newer than my 2019 version), then the plenum volume has been significantly increased since I bought mine. Also I notice that the newer regulator is no longer threaded to the plenum spacer.

I have the same problem as you !
But you already know that
