Huma-Air Tuning Regulator For The Kral Arms Breaker

For the Kral Arms Puncher Breaker bullpup airrifle we have a pressure regulator available that can be pushed into the pressure tube.
This Huma Kral Puncher 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 during time.
This  model is not suitable for the Puncher NP3.
This regulator with plenum is suitable up to caliber .25
 

The benefits of the Huma-Air, Kral Arms Breaker tuning regulator are:

• 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.
• Adding a regulator to your airrifle 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 

When you order your Huma-Air, Kral Arms Breaker tuning regulator you will receive:

• Your regulator preset to your own wishes;
• A pressure scale in Bar’s on the regulator, for fine-tuning or re-adjustment;
• We will include a “Huma-Air regulated” breech sticker;
• Fitting instructions as pdf download 

Huma-Air Quality Control  

Huma Air regulators are CNC produced out of high grade aircraft aluminum and bronze. To guarantee a perfect product, every regulator is individually assembled, tested in a computerized simulation program and adjusted to the requested pressure. 
We only use high-end materials and our belleville springs are designed for critical applications to achieve the highest repeat accuracy. This gives our regulators a repeat cycle less than 1% difference.
Huma Air provides a 2-year warranty on their regulators. Excluded from warranty are shipping costs and parts that are subject to normal wear and tear such as o-rings and valve discs.

 

Pressure settings of the Huma-Air, Kral Arms Breaker tuning regulator 

The tuning regulator comes preset on the most common pressure setting, or we will adjust it according to your personal wishes.
It is also equipped with a clear pressure scale label, so you can very easy re-adjust or fine tune the pressure setting suitable to your wishes.

Why would you need a regulator?

A bit about PCP basics:
A PCP air rifle has a high pressure air reservoir. When firing the rifle, a “hammer” slams on a valve what will open a little and a certain quantity of air escapes. This airflow speeds up the pellet.

In an unregulated air gun you normally start with a pressure of about 200 bar. But after every shot this pressure will decrease. You can imagine when the hammer slams the valve and there is 200 bar of primary pressure on the valve, it will only open a tiny bit and giving the pellet a certain speed. After a few shots the primary pressure is reduced and there is far less pressure pushing against the valve; but the hammer still slams with the same force, so the valve will open more, giving your pellet a higher speed.  Therefore you can see you point of impact (POI) “climbing” after a few shots. Then after a certain more shots, pressure drops even further and your POI will go down again.

A regulator is a kind of internal pressure regulator that divides your pressure tube in two sections. The first large section contain the “primary” high filling pressure. The second section is just a tiny pressure chamber (plenum) that contains a certain quantity of air with a pre-set pressure that is needed for the pellet speed you desire. This we call the secundairy or regulated pressure. The regulator will keep this pressure constant every shot, until the primary pressure is equal or lower to the set pressure of the regulator. This will result in a very constant pellet speed, and also a steady POI of your pellet.


More benefits of using a regulator in your PCP.

Your rifle is set up to work in a relatively large pressure range.
After fitting a regulator you can optimize your rifle for the lower, constant, working pressure.
This means that you probably do not need as much hammer spring tension as before. This can also reduce air consumption.
Sometimes the hammer weight can be reduced too, this will give less movement inside the rifle. This will optimize the shooting behavior of your rifle.
On  several internet forums you can find tons of info for “tuning” your specific rifle in combination with a pressure regulator.
