Old vs new Matador regulators
Hi,
I noticed there is a new Matador regulator introduced in 2017. According to Huma, their regulator will fit the old version only:
Can someone shed some light on the differences? Can one use the same reg tester to handle both types?
Assuming that I have the old regulator and I fitted Huma reg – won’t the shooting chamber be bigger?
Thanks!

Valve TP:
.22 = 5.2 mm
.25 = 5.8 mm
Valve seat:
22 = 5.5 mm
25 = 6.5mm
Forward breech TP:
22 = 5 mm
25 = 5.5mm
Keyser, would you be that kind and tell me what is the TP’s diameter size in 5.5 and 6.35? I am talking about the hole which is sealed by a brass ring.
Thank you. It’s good to have you in community.
No the only difference is the TP size .
Thanks. How about the difference between .22 and .25? Is there any difference in the regulator region? Bigger plenum in .25 or something like that?
Right. I would call the area in the green square the regulator housing
OK. Thanks.
So the only difference is in the part contained in a green frame, right? Rest is the same.
Yes it does increase the plenum size. They also fill slower than the OEM regulator. This can be adjusted but I have never seen the need to. I usually run the Huma air about 10 BAR lower than the factory. On my 22 Matador I run the regulator at 120 bar and it gives me 920 FPS with 18s . These regulators are the best way to get 34 grain power from your 25 long.
Ok, so it makes a shooting chamber bigger, doesn’t it?
The red square area is all that is replaced when upgrading the Huma . The internals are also removed from the OEM regulator (piston washers)
Thank you for such a great level of details.
So Huma reg replaces a red part or a green one?
Yes your Reg tester will still work because the area that seals the tube is still the same size
Here are the differences with the regulators. I can’t remember why Ed said he changed it. Huub has the measurements for the new regulator if you want to change out the factory one with a Huma-Air (Note the new one was damaged by accident by a customer)
