Huma BSA Ultra MMC Pressure Regulator (External)

This regulator is specially designed for tuning your Bsa Ultra mmc air rifle.
It is very easy to install on your rifle, just depressurize the rifle, unscrew the pressure tube and screw the regulator between valve house and pressure tube and you 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 and we designed it for a wide pressure range (70-150 bar) to suit sub 12 ft/lbs (UK) and high power FAC models.

The benefits of this regulator over other regulators currently on the market:
Higher accuracy of your rifle due to the elimination of the pellet speed fluctuations.
A constant pellet speed over the full working pressure range.
It will give you a better shot count and a full flat shot string 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 air rifle will probably give you the biggest benefit in the tuning process.

When you order one of our regulators you will receive:
Your regulator pre-set on to your own wishes.
A pressure scale in Bar’s on the regulator, for fine-tuning or re-adjustment.
We will include a “Huma regulated” breech sticker.

Pressure settings of the Huma-Air, Bsa Ultra MMC tuning regulator (external):
The Huma-Air, Bsa Ultra MMC tuning regulator (external) comes preset on the most common pressure setting according to your choice of barrel and caliber, or we will adjust it according to your personal wishes. The length of the barrel is measured from the magazine until the tip of the actual barrel (not the end of the shroud). After fitting the regulator, always check the power setting of the rifle and finetune it when needed to stay within legal limits.

Due to his length, this reg has a restricted air volume, so this makes it especially suitable for the 12 ft/lbs – 16 Joule versions. The maximum power of the reg is about 25 ft/lbs – 35 Joule with a 47 cm barrel. If you are looking for a higher 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 valve house and check if your transfer port is between 4 - 4,5 mm. Otherwise open it up for best performance.
