Huma-Air BSA Scorpion pressure regulator (external)

This regulator is specialy designed for tuning your BSA Scorpion and BSA scorpion T10 airrifle.

It’s very easy to install on your rifle, just depressurize the rifle, unscrew the pressure tube and screw the regulator between valvehouse and pressure tube and your are finished.*

We copied the original BSA valve body thread to allow the body of the regulator to be screwed directly to the valve body and air cylinder.
Important to know that the regulator ads 36 mm of length to the pressure tube.
When you have a Scorpion with a 320 mm long pressure tube you can probably still fit a HW silencer. For the other models BSA’s please check if your silencer will still fit the rifle when the regulator is placed. You will probably need a 27 mm silencer.

The benefits of this regulator over other regulators currently on the market:

Higher accuracy of your rifle due to the elimination of the pelletspeed fluctuations
A constant pellet speed over the full working pressure range.
It will give you a better shotcount and a full flat shotstring immediately.The regulator housing is made of extremely tough 42Cr steel,
Tested for a working pressure of at least 3x the working pressure of the rifle, for everyone’s safety,
It uses a long stroke piston that gives great consistency.
The regulator body and the housing are one piece, so no chance of the regulator moving inside the cylinder,
The one piece body and regulator housing also reduces the possibility of leaks,
The regulator piston is captive and does not need any adjustment or extra work to keep it in place,
DIY fitting is a real option for the most people,
High quality bluing, same colour as the original BSA pressure tube,
Adding a regulator to your airrifle will probably give you the biggest benefit in the tuning process.

Due to his length, this reg has a restricted airvolume, so this makes it specially suitable for the 12 ft/lbs – 16 Joule versions. The maximum power of the reg is about 25 ft/lbs – 35 Joule with a 47cm. barrel. If you are looking for a high power regulator for your BSA mmc rifle please take a look at our high power internal regulator

* Please remove the brass restrictor part out of the valvehouse and check if your transferport is between 4 - 4,5 mm. Otherwise open it up for best performance
