Designed for the Air Arms S400/S410 and S500/S510 series of .177 and .22 air rifles, this pressure regulator can be used with the original air cylinder. It will give you better consistency and shot-to-shot accuracy immediately.

This regulator is vented to the atmosphere with minor modification to your pressure tube. This will prevent the regulated pressure from creeping up between shots.  Simply slide the regulator into the pressure tube following the included fitment and modification instructions.

The regulator has a seperate volume bus (plenum) matching the caliber and preferred power.
The regultaor body is only 16 mm long and the regulator neck is round 13 mm with a length of 15 mm. So there is almost no loss of air volume in the pressure tube.

Benefits to using this Huma Regulator:
Higher accuracy due to the elimination of the velocity fluctuations.
A constant velocity over the full working pressure range.
Maxiumum use of the air volume due to the ultra compact build.
Better shot count and a flat shot string immediately.
Adding a regulator to your air rifle will probably give you the biggest benefit in the tuning process.
Often the rifle will make less noise due to better balance in air usage.

The regulator is CNC produced out of high grade aircraft Aluminum and bronze.
To guarantee a perfect product, every regulator is manually assembled, tested and adjusted. 
Huma only uses belleville springs designed for critical applications to achieve the highest repeat accuracy. This gives their regulators a repeat cycle less than 1% difference.
