Hatsan BT65 tuning regulator


For the Hatsan BT65 we have a tuning regulator available what will boost your airrifle's performance to the highest shot consistency and best accuracy.
This regulator is vented to the atmosphere without any modification to your pressure tube. So no drilling in the tube and also no creeping up in power during time.
it will fit all the Hatsan BT65 versions.


The benefits of the Huma-Air regulator for your Hatsan BT65:

  • Higher accuracy of your rifle due to the elimination of the pelletspeed fluctuations
  • A constant pellet speed over the full working pressure range.
  • Maximum use of the air volume due to our ultra compact build.
  • It will give you a better shotcount and a full flat shotstring immediately.
  • Adding a regulator to your airrifle will probably give you the biggest benefit in the tuning process.
  • Often the rifle will make less noise due to better balance in air usage

When you order your Hatsan BT65 Tuning Regulator you will receive:

  • Your regulator preset on to your own wishes.
  • A pressure scale in Bar on the regulator, for fine-tuning or re-adjustment.
  • We will include a “Huma-Air Regulated” breech sticker.
  • Fitting instructions as pdf download

Pressure settings of the Hatsan BT65 Tuning Regulator


Your Hatsan BT65 regulator comes preset on the most common pressure setting. It is equipped with a clear pressure scale label, so you can very easy re-adjust, or fine tune the pressure setting without the need of a regulator pressure tester.
The output pressure range is adjustable from 90-170 bar. 

Aditional information:


Only when you have bought your rifle in- or after 2017,  please let us know the production date of the pressure tube. This date is printed on the fillcap in month/year.
For older rifles it is not necessary.
The .30 version is currently not suitable for rifles with a production date starting from 2018


Huma-Air Quality Control


Huma-Air regulators are CNC produced out of high grade aircraft Aluminum and bronze.
To guarantee a perfect product, every regulator is manually assembled, tested and adjusted to the requested pressure. 
We only use high-end materials and our belleville springs are designed for critical applications to achieve the highest repeat accuracy. This gives our regulators a repeat cycle less than 1% difference.

Prodotto ottimo. Seguendo le istruzioni che ho trovato sul sito non ho avuto alcun problema a installarlo e trovare la regolazione ottimale per la mia BT65. l'ho tarato a 140 bar e, dopo avere lavorato anche sulla spinta della molla come indicato da Huma, riesco a tirare fino a 60 colpi senza notare variazioni di preciisione.
Apprezzazbile anche il supporto tecnico a cui avevo rivolto alcune domande prima di procedere all'installazione-
Veramente consigliato.

Na het monteren van de Huma regulator in de drukbuis van mijn Hatsan BT65 SB
afgesteld op 130 bar een merkbaar verschil in de geschoten groepjes.

Really great product. The regulator has increased my accuracy by so much. I'm getting one inch to one and a half inch groups at one hundred yards. I would really recommend this regulator as it's worth every penny.

Excellent regulator for taming my Hatsan BT65 SB Elite!
Good flat response ~1015-fps @ 130-bar using H&N Baracuda 10.65gr (I will be experimenting more with even lower pressures)
Lovely machining, easy to install and no modification to the original air pressure cylinder necessary.
Arrived in record time and really like the way the Huma team keeps the customer informed every step of the way and prompt response to all questions.

After a lot of research and reading reviews on the Huma regulator, I decided to purchase on for my BT65 and Galatian. So far it's been one the best decisions I have made as far as getting better performance from my rifles. Installation was quick and easy. Instructions were simple and easy to understand. Accuracy and shot count have improved dramatically. When I need another regulator for one of my air rifles, this will be my first stop.

Bought this regulator to tame my BT65SB, .177 cal from 35ft/lbs, 1250 fps to below supersonic and get the accuracy from 'shotgun style' to where it should be. Very high quality regulator, easy to install - I did use the second method of installation filing through the valve threads to allow regulator to vent. Ended up with the regulator set at 100 bar from 140 bar. Velocity down to 925 fps, muzzle energy around 22 ft/lbs and the consistency is incredible. Ping has also gone from the cylinder. Shot count up, air consumption greatly reduced. Using 10.65 grain pellets. Great product and Huma customer service is also very good.
Well done Huma Team, thank you.

This is the second Huma I own , I have fitted the .25 regulator in a .22 for the bigger plenum volumn this is giving me 30 shots @ 40fpe with 21grn pellets. Very good product .

Al final no lo llegue a comprar.
Ya tenia uno, pero la verdad es que funciona bien.
La única pega es que por debajo de los 110-100 bares, no va tan fino.
