AEA Aftermarket regulator options for AEA standard Challenger .25 cal?

[OC_]

The factory AEA regulator on my .25 challenger has stopped regulating and I was wondering if there is any options from 3rd parties. Its really disappointing since the one in the gun now is already a replacement. I figure that these AEA regulators are just garbage.

I have been in contact with Huma, but their regulator says its only for the Bullpup, not the Standard model. I find this confusing because both of the guns are essentially the same and have the same tube. I emailed Huma, Met Vriendelijk Groet responded and the response didnt make sense. Clearly, English is his second language so im wondering if he meant something else. He said that the Plenum size on the standard model is too large, and thats why the reg wont work. But neither the bullpup or the standard have plenums to begin with - just a tube.

I then asked him what the OD of the regulator was. He said it was 29mm... This sounds like it will work since my airtube is 36mm. But im not sure. I'll take an ID measurement when i get home.
I know that bullpups from 2021 and older have the 36mm air tubes, after that, they went to a 41mm.

Anyhow, is there anyone else in the market that makes a reg that will fit my gun?

Huma is based out of the Netherlands, so your right.....English is probably not their first language.
Have you attempted to use Google to translate the e-mail?
Huma knows exactly what they are doing, so if they say it will not work, I would not second guess them.

Did you try to call them? When buying from Krale I found that it's much easier to just call their customer support and get all my questions resolved at once instead of mailing back and forth for days one email a day. And their English was fine . Though there is a time difference, I had to call at 1am at night .

I would check with Bintac. Those folks mod AEA products.

I did talk to Bin at Bintac, I got the gun through him originally. I also got my first replacement reg through him as well.
I did hear back from Huma over email. It looks like the bullpup reg will work. I was hoping i could get a reg without a plenum built in because I already have a plenum for the AEA reg.

The ID of my tube looks to be about 29mm, which is what i measured. If i understand Humas email correctly, their bullpup reg is for 29mm ID tubes.

I ended up getting the Huma regulator even though they didn't have the words to explain why it might not work. Well, it does work, but there is a caveat.
It turns out that there is a step inside the air tube that increases the ID. I'm not sure why its like this, but I know a little bit of a relief is needed to fit over the long valve. I think this is what Huma was trying to say. But it turns out, all i had to do was take off the mano/fill probe end and install it on the other side, flipping the tube around. That side still has a step, but it doesn't go very far into the tube and the reg fits properly. So, the "bullpup" Huma regulator does work. The only downside being that the tube does not screw all the way down because there is no clearance for the main valve. But the gap is minor and the threads are still fully engaged. Huma also says not to screw it all the way down because it needs to vent there. So, everything is looking good! Can't wait to go shooting!

Not much to take a picture of since it’s all internal. But here is a pic of the gap where the air tube meets the body. I got the regulator directly from Huma. It came in less than a week.
