Hatsan BT65 HuMa Regulator - DIY Fit
This is for a DIY fit HuMa internal regulator for the Hatsan BT65. It is best suited to people who have a good understanding of their rifle and who know how to adjust the power.
For the Hatsan BT65 (also called Hammerli Pneuma) we have designed a regulator what can be fitted into the pressure tube/air cylinder. This regulator is vented to the atmosphere without any modification to your pressure tube/air cylinder. So no drilling in the tube and also no creeping up in power.
The regulator is CNC produced out of high grade 7075 Aluminium. Every regulator is manually assembled, tested and adjusted to the requested pressure. Of course the regulator can be easily adjusted up or down in pressure if needed
Please note that the 2018 models have slightly different size air cylinder so these regulators will not fit, these are for rifles made before 2018.
They are available for .177, .22 and .25.
This regulator is only suitable for FAC/high power rifles, it is not suitable for sub 12ftlbs rifles unless you know how to tune your own rifle and adjust the regulator pressure.
The fitting instructions can be found on the HuMa Air website
Before ordering a regulator, please make sure you have made yourself familiar with the fitting instructions on the "Fitting Instructions" page on the website, you are happy to carry out the necessary work and you are able to adjust your power to keep your rifle legal.
You will need access to a chronograph to set the power once the regulator has been fitted.
Please do not exceed the legal power limit for your country/state.
