SPA P12 Bullpup HuMa Regulator (sub 12ftlbs) - DIY Fit
This is for the latest version DIY fit genuine HuMa internal regulator for your sub 12ftlbs/16J SPA P12 bullpup.
By special request HuMa Air have designed a regulator for the Chinese SPA P12 PCP airrifles.
This regulator is very easy to install; just slide it into the into the pressure tube and you are done in the FAC models, in low powered rifles you may need to open up the transfer port and balance the hammer and firing valve spring.
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.
It will give your rifle an almost flat shotstring due to a constant pellet velocity.
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
They are available for .22/5.5mm and .177/4.5mm

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.
