HW100/HW101 HuMa Regulator - Internal - DIY Fit
This is for a DIY fit HuMa internal regulator for your Weihrauch HW100 or HW101, it is suitable for 12ftlbs/16j models and FAC/export models. The DIY fit model is useful if you do not want to post the complete action or cylinder, you are familiar with the workings of your rifle and you know how to adjust the power. If in doubt about the fitting instructions, please seek the advice/services of a professional.
Because this regulator fits inside the air cylinder it makes no difference to the overall length of the air cylinder or the looks of the rifle. It does not involve drilling a breather hole in the air cylinder, unlike some other regulators on the market. You will need to ensure the inside of the air cylinder is well polished to allow the regulator O rings to seal properly. You may also need to disable the standard regulator (covered in the fitting instructions).
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 able/happy to carry out the necessary work and you are able to adjust your power to keep your rifle legal. There are no printed fitting instructions sent with the regulator.
For more details about the regulator have a look on the HuMa Air website.
You will need access to a chronograph to set your power after fitting the regulator.
Please do not exceed the legal limit for your country.
