Made on special request for the HFT and UK shooters. Huma Air in close cooperation with Airborne Arms NZ, developed this tune kit for the Edgun Leshiy to convert your rifle into a 12 ft/lbs (16 Joule) HFT version with an enormous shotcount.
Our kit contains our micro regulator, a special plenum with a matching valve return spring, a power sleeve and a new softer hammerspring.
The kit is specially designed for .177 but also works fine for .22 and it is capable of providing you an huge shotcount with the highest shot to shot consistency. (see the shotstrings below) 

The benefits of the Huma-Air, Edgun Leshiy tuning regulator set are:

  • Huge increase in shotcount
  • Easy to adjust due to the pressure scale, you do not need to gues, or use a reg-tester to set the pressure
  • This regulator comes in our special low pressure range of 60-120 bar
  • Excellent consistency
  • Higher accuracy of your rifle due to the elimination of the pellet speed fluctuations
  • Tested in .177 and .22. (no test data for .25 available yet)
  • (Maximum power for this model is tested @ 21 ft/lbs in .22)

When you order your Huma-Air, Edgun Leshiy tuning regulator set you will receive:

  • Your regulator preset to your own wishes;
  • A pressure scale in Bar on the regulator, for fine-tuning or re-adjustment.
  • A delrin powersleave
  • A new valve return spring 
  • A new hammer spring
  • We will include a “Huma regulated” breech sticker;

If you want to do some more tuning; the regulator has a clear pressure scale so you can easy adjust it to your wishes.
These regulators are also vented to the atmosphere without any modification to your pressure tube needed so no creeping up in power.

This Edgun Leshiy regulator model is deveopped and tested in cooperation with Wingman of Airborne Arms NZ. Check his results and fitting instruction in this direct link to to video
Not every rifle is identical and you might try some different setups to get the best results. 


Please note: these shotstrings are made by "Wingman" of Airborne Arms. He is an skilled tuner and spent a lot of time in finding the best performance for his Leshiy. He used a 300 bar fill pressure. (Please check your rifle's owner manual for your maximum fill pressure). His instructions video will give a good indication of the setup, to tune and adjust your rifle to the best performance you do need some skills in adjusting your hammerspring tension and regulator pressure combination.

Beside the Gen1-Gen2 differences, there are also some different strengths/types of hammersprings used in some leshiy rifles. These rifles might need some different setup and can give another performance.
Please check the tab "Reviews" of this regulator were we share the user feedback and their setup used. Per 1-2018 we include an new softer hammerpring to the set.

Easy purchase, fast delivery, excellent back up support, sale price. Great product which works well. Easy to install, great fit. So much to like.

Only 4 stars though as the setting instructions (third party) though good were not entirely clear to me; some relate to preproduction versions. A basic starting point and procedure for finding optimum would be useful.

A replacement or perçut valve option would be an advantage.

The perfect upgrade for U.K. Leshiy owners. More shots per fill, more consistency and it even makes the gun quieter. Added to that it’s so simple to install although a spare valve stem might be a wise addition to your order if you’re not confident about cutting the stock valve stem to size.

Bill - 07-12-2020 20:37

Huma provide very fast shipping to the U.K., 5 days from ordering to receiving in my case. The reg is easy to fit and gives very consistent shots, increased shot count and it also makes the Leshiy much quieter too. This is a ‘must have’ for anyone wanting a sub 12 ft/lbs rifle. I would highly recommend keeping the standard hammer spring (adjusted to suit) and fitting the Delrin plenum insert for best efficiency.

Very consistent output and high shot count - what's not to like

Jim - 23-12-2019 15:08

An excellent piece of kit that has transformed my Leshiy by extending the number of shots per fill which results in great fun.

Excellent quality product. Very well made regulator, easy to install. More shots, tighter strings

V1ktor - 19-04-2019 17:34

An excellent product, oozing quality.
Increased shot count with tighter spread = more consistent shooting.
It really has transformed my Edgun Leshiy.

Initially fitted with the insert and a quick chrono session.
Remove insert and repeat.
Figures indicated no need for insert in my setup.

A breeze to install and adjust. If a spare valve was included for the price the kit would be worth every penny.

Absolutely superb

Sactargetshooter - 21-03-2018 05:04

Excellent quality product. It took some experiments and lots of hand pumping to figure out the most optimal configuration. With a .177 caliber 250mm barrel, I get about 60 shots from 250 bars down to 80 bars, 11 FPE each shot. Reg. is set to 85 bars and the delrin insert is left out. At least with a .177 barrel, increasing reg. pressure to 120 bars and putting the delrin insert in did not improve shot count from 200 bars to 150 bars compared to 85 bars and no insert. A .22 gun is probably a bit more efficient due to the increased cross section area and utilize the higher pressure better.

More shots, tighter strings, excellent support with installation which was very easy. Delrin insert offers greater tuning flexibility depending on personal preferences. A shortened valve stem would be a good addition to the kit though as this would allow you to keep the original in tact if ever required. Even if it increases the cost slightly. Really pleased.

Very well made regulator, easy to install. Getting 90 shots from a 250 bar fill, regulator set at 100 bar in my .22 Leshiy. Fantastic consistency. I do think that the reduced plenum should be one piece though, negating the need for the delrin insert.


Phiroze - 08-10-2017 11:05

I received my sub 12 reg sooner than I expected .. it took me a few days to gain the courage to install it as I had to cut down the valve stem.. it would have been great and stress free if a shortened machine cut valve stem would come with the kit.. that would be my only gripe..

I still have some more testing to do but I’m very happy I made the choice to install it already.. way more number of shots that I ever expected from this little goblin and consistency on par with the original.. ave spread 10fps..
All round Def a happy customer..

I bought this tuning kit prior to the delivery of my Edgun Leshiy which arrived last Wednesday. I had ordered a 12ftlb version as I live in France whose power limit is 20 joules and to stay legal I could only buy a sub 20 joules air rifle.
Prior to purchase I watched the installation video several times and assessed that the modifaation to the valve was within my capabilities and in my comfort zone.
The kit arrived very quickly and it waited until the Leshiy was delivered.
I did the first chrono runs as it was delivered and it had been very conservatively but never the less legaly set to sub 11 ftlbs.
The modification went well and I left the reducer at factory 110 bar as it was my intention to run the air rifle at

Hi i have a Gen2 Leshiy ,serial number 057X .20 cal 250mm short barrel.
i discovered my leshiy has an extremely stronger than normal hammer spring fitted so i had to try all variations of settings between reg pressure and hammer tension to get the best tune for my setup and needs,
My sufficient needs require no more than about 11ft/lbs / 600fps , so that was the aim for my tune.
after lots of testing i have got it just right.
Using the new Huma sub12 hft regulator kit, i have the regulator set at 82bar and my hst is 12clicks from lowest.
Using unsorted/unweighed straight from the tin JSB Exact .20 Diabolo 13,73gr Pellets
i have achieved 85 tight consistent shots from a 250bar air fill down to around 70bar air where it then drops off with no power spike. see results below...........

Shots 85
min power ft/lbs 10.51
max power ft/lbs 11.09
min speed fps 587.0
max speed fps 603.0
average power 10.90 ft/lbs
average speed 597.7
max spread 16.0
gem deviation 2.6

I am extremely happy with these results!
85 shots for such a small rifle with small cylinder Amazing!
I highly recommend this kit!

I have a Gen2 Leshiy, serial number 062X.
I have tested the regulator with three barrels between 90 bar and 120 bar and have found 105 bar reg setting to be best on mine.

The short .22 barrel gave me +100 consistent shots using 18.1gr JSB 5.52.
(300 bar fill pressure)

The short .177 barrel gave me +80 consistent shots using 8.4gr JSB 4.51.
(300 bar fill pressure)

The long .177 barrel gave me +90 consistent shots using 8.4gr JSB 4.51.
(300 bar fill pressure)

I kept the power around 11.5 ft/lb via the hammer spring adjuster, which was normally 2 or three clicks either way depending on which barrel I used.
With the regulator set at 120 bar the power did creep just over 12 ft/lb after it fell off the reg with all of the barrels but it is fine set at 105 bar.

Double the shot count and very little deviation compared to the original regulator.
Very happy with mine!
