Micro Huma Regulator for Edgun Veles and Lelya
So I had a day of and got playing with the .177 Veles pistol. I got thinking, If I could get 20% more air volume in the Leshiy by making this micro reg what would one do in my Veles.
I got to work and cut another O ring groove in a Huma micro reg and made a small plenum spacer to align the breather hole in the Veles tube.
The result again is a slightly larger plenum volume to work better with lower reg pressures and the new reg almost doubles the usable cylinder volume in the .177 tube!
The larger plenum volume let me turn the reg pressure down to 95 bar from the factory set 130bar of the Edgun reg which got the same velocity without touching the HST as the Edgun reg at 130bar.
After a little fine tuning check out this shot string!
Start pressure 250bar: FPS= 734, 730, 731, 732, 731, 729, 730, 729, 730,729, 730, 730, 728, 731, 728, 728, 728, 728, 729, 730, 727, 731, 729, 729, 727, 708fps end pressure 80bar
So 25 usable shots in the .177 at a slightly higher velocity than before (680fps).
This reg will fit the Veles .177 and .22cal pistols and also Lelya bulpups in .177, .20 .22 and .25 cals.
I have sent all the data and dimensions to Huma Air and they have made these regs available to everyone.
Give Brian at Edgun West a shout if you want to order them in the USA.

Just a quick note for anyone getting one of these for a Matador.
I have an early Matador R3 .25 long. I picked up the Huma reg, but when I tired to replace the edgun reg., it doesn’t quite fit. I think that the problem is that the OD of the body of the Huma reg is 1.195 inches, and the body of the edgun reg is 1.175. There is a very slight restriction in the air tube, and the bigger OD of the Huma reg is just enough to keep it from sliding in all the way.
I think there were some changes in the reg from the first R3s to the next, and it may be that this is a problem for only a small number of guns, but I don’t really know. On the pother hand, since the seals are orings, it seems like the body diameter could be reduced slightly without any adverse affects for any version.
I did test the Huma reg in a tester, and it seemed to work great. Just not in my Matador. I’m going to drop a note to Huma and see what they say.
O.k., that makes sense, thanks.
The valve is in behind the plenum, it remains untouched.. there is no need to remove the vavle or plenum.. just the reg body.
If someone wanted real performance out of the 34gr heavy .25 cal JSBs the old reg body could machined out more to a thin walled tube to get a plenum even larger than Eds .30cal unit.
Larger plenums mean you can run lower reg pressures to achive the same or higher velocities providing you have enough barrel length.
This means the Matador valve which in the .25cal is already over worked is under less stress during the shot, it also gets quieter due to less HST needed meaning the whole system isnt working as hard.
This is a great mod for the .30 cal matadors too as they really shouldnt be set over 130 bar due to the valve stress and under rated hammer system.
Does this maintain the same spacing with respect to the hammer? So you can use the same valve stem? It’s been a while since I pulled out a reg and I’m having trouble picturing it.
interesting !
i have both,
i’m getting’em both ! thanks for all info NZ

Thanks a lot very helpful

Great advice here! Thanks Wingman.

The complete reg is removed at the first thread including the piston and washers. That leaves the std housing for the piston and washers as additional plenum space as the Huma is a smaller self contained reg that threads on the end.

Yes follow the link in my post to suppliers.
The matador reg isnt much smaller than the std Edgun reg but uses the old reg body as a plenum extension which makes the best use of lower reg pressures for better air useage and tight shot strings.
You remove only the washers from the matadorĪs regulator or the complete system ( washers and holder)under the tap due to install the new huma tap-reg?

I love that pistol
Now, can the huma-reg be fitted into the Matador. I know the standard .22 Matador get a good 70+ already.
That’s awesome. Question is, if it is possible to make the reg so small, why is the edgun one so big?

Wingman do you think it would work to install one of the in my .22 Lelya and use the extra volume to increase the FPS and get around the same shot count?
