Hatsan AT-44 HuMa Regulator - DIY Fit
This is for a DIY fit HuMa internal regulator for the Hatsan AT-44. It is best suited to people who have rifles with no anti-tamper and who know how to adjust the power.
The regulator can be slid into the air cylinder of the Hatsan AT-44, it does not need the air cylinder to be drilled, unlike some other regulators.
This regulator is vented to atmosphere without any modification to your pressure tube. So no drilling of 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.
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 don't exceed the legal power limit for your country/state.
