yes, after your item is shipped you will receive a track and trace link so you can follow the parcel. (Unless it is mentioned differently)

If your items were in stock at the time you ordered them, and you did not received a track email after max 5 days, please check you spam/unwanted email folder. The track and trace email is sometimes marked as "spam" by some internetproviders.
Our logistic partner uses "Tracking" as sender name.

In transit means that the package has left our mail depot into the direction of the destination country. It is therefore currently located between countries.
Upon arrival in the destination country it will go directly to the customs services for inspection.
As soon as the package is released, it is hand over to the local postal services and the track and trace will be updated. This period can last between 1 and 6 weeks.

This means that there was no error in the shipping process. Otherwise you would have received an email notification and the notification would have indicated on the screen: Error Notification : Sent -date-

The expected delivery date in the tracking link is just a general indication and does not include customs retention period and delays due to Covid19.
Custom retention can be between 1 and 8 weeks depending of the speed of your countries custom services.

We use tracked priority sending services (unless mentioned different) with our contract partner Logic parcel.

When we ship outside the EU, a custom declaration form is required. Al our high pressure air parts are shipped as "pneumatic parts"

We cannot ship parcels to PO boxes or APO boxes.

Do not sign for proper delivery if the parcel is visiblily damaged. You can accept the parcel, but let the driver make a mark of the damage. Also take pictures before opening the parcel.

it means that it has actually been sent.

Our courrier will update the track and trace normally within 48 hours during working days.

Untracked shippings:

As mentioned on our website, some small parts are standard sent without track and trace to reduce your shipping costs. In this case you will not receive a track and trace code and your items were sent by normal letter post.

You can trace your items by using the links you received in your email when the parcel was sent.

Or a good international tracking service can be found here:

From the moment the track shows a parcel was sent abroad or in transit, it has to be processed by your countries custom services, the legal period for a custom investigation is maximum 6 weeks. These circumstances are beyond our control and can cause delay. As soon as the parcel is hand over to the local courier services the track will be updated again.

Average shipping time can time can be anything between 1 and 8 weeks depending of the speed of your countries custom services.

You can trace your items by using the links you received in your email when the parcel was sent.

If there is no movement in the supplied track and trace code for at least 4 weeks, we can start an investigation of the shipment. If there is no movement in the trace for 6 weeks we consider the parcel to be lost and you can contact us with your order number and track and trace code for a replacement shipment.
So if there is no movement in the track and trace for 4 weeks, you can contact us by filling in the contact form

No, never exceed the factory adviced fill pressure of your rifle! When an o-ring in the regulator would fail, the (higher) fill pressure will be on the action of your rifle and it is not designed for this. This can cause a dangerous or even lethal situation.

If you want to know more about pressure settings or fine-tune your rifle check our general adjustment tips what can be found in the fitting instructions page

Because there are numerous combinations of pellets, pellet weights, pellet speed etc. it is not posible for us to test them all,
So unfortunately we cannot give any advice about shotcount, air consumption and pelletspeeds.
This kind of information can normally be found on the bigger local and international airgun forums like Airgun Nation were people share their results.
If we have information available about our own test results, it can be found in our fitting instructions page

If you want to shoot extra heavy pellets you might consider selecting a larger caliber regulator, so a .25 instead of a .22 or a .30 instead of a .25 These plenum sizes are bigger what will have a positive effect one the pelletspeed with the extra heavy pellets.

A regulator plenum or secundairy volume chamber is the space behind the actual regulator what stores a certain amount of air, at the regulator set pressure, needed for a shot.

No, plenum sizes are caliber and power specific, for example, the .25 caliber models are physically larger when compared to the .22 caliber models. .30 calibers will be even longer.

Yes, setting the regulator output pressure is as easy as turning up your central heating:
In between the slots of the set screw there is a very fine mark on the side of the set screw, indicating the set pressure.
If you want to change the pressure setting of your regulator, please follow the manual how to adjust the regulator pressure in the fitting instructions page

When a regulator is brand new or it has been rebuild, the valve seat and setscrew need to wear into eachother. This is what we call the "inbedding" of the regulator and it will improve accuaracy after a period of use.

For any questions about fitting of the regulator to your rifle, please check the fitting instructions page of our website.
We list all information we have available and we will also share thirth party information.
Also on many bigger airgun forums there is a lot of information to be found about specific settings and set-ups.

A regulator can only let air through one way, from high pressure side to low pressure side. So in case of a CZ200 a quickfill on the other end of the tube is necessary. And you cannot fill your scuba tank trough an external inline regulator

No, the low pressure regulators have a different spring packet.

In between the slots of the set screw there is a very fine mark on the side of the set screw, indicating the set pressure.
If you want to change the pressure setting of your regulator, please follow the manual how to adjust the regulator pressure in the fitting instructions page

When your pelletspeeds climbs up at the end of the shotstring, the regulator pressure is set to high compared to the hammerspring tension. You can increase hammerspring tension what will create a higher pellet velocity or reduce the regulator pressure and also re-adjust the hammerspring tension again to get the best balance

A regulator is not a direct "On/Off" type of valve but it is a delicate balance between forces. During a period of not using the rifle, the pressure in the regulated chamber can go up slightly higher, causing the first shot to have a higher or lower velocity.

This is a normal symptom and not to be confused with regulator creep.

Pellet speed fluctuations can have different causes:

When you shoot over the chrony, shoot slowly like you are on the shooting lane and use a good fixed position of your rifle.

When the regulator is brand new fitted to the rifle, it indicates the balance between regulator pressure and hammerspring tension is not correct. Check the general airrifle adjustment tips for setting up your regulated rilfe properly.

Too much grease on the hammer or hammer spring can cause a "sticky
hammer" causing pelletspeed fluctuations.

A defective o-ring on the pelletprobe or transferport can give fluctuations in pelletspeed.

When your regulator is used for a longer period and it starts being inconsistant it might need a rebuild. More info about a rebuild can be found here: regulator revision instructions

When a regulator is brand new it needs to get worn in, this is what we call the imbedding period of the regulator. During this period the pressure can vary a bit before it get fully stable. This is not regulator creep but a normal phenomenon.

Regulator creep can have a few causes:
A tiny scratch on the delrin valvedisk or dirt between the setscrew and valvedisk. Flipping over the white valve disk will probably solve the issue.
The other option is a defective o-ring of the setscrew, in this case the reg does not stop creeping and the regulated pressure gets equal to the fill pressure.
The last option is there is a scratch on the setscrew tip, this is highly uncommen but you can check it with a magnifier glass.

Please follow the regulator revision guide before you start. It can be found in the fitting instructions page of our website

An air leak is never rocket sience but it can be very anoying. A large shissing leak indicates an o-ring what is not seated properly.
Small leaks are 9 out of 10 times caused because the inner wall of the pressure tube is a bit rough or the surface were the regulator stands on is not smooth enough. A good polish will probably solve the problem.

Inside the regulator there are a few o-ring what will by used dynamicly. So when you notice fluctuations in the pelletspeed it might be time for maintenace or rebuilding your regulator:

We have complete rebuild kits available in our webshop including our special delrin valve disk and low viscosity silicone grease.

As long as you open up the regulator at the back side with the C clip, the setting stays about the same and you can service and swap o-rings. When you want to unscrew the set screw, alway measure the total lenght of the regbody + screw so you can screw it back together in the same length. Please follow the regulator revision guide for full explanation. It can be found on fitting instructions page of our website.
