Huben Tuning Service for GK1


**Only Available for European Union**

As any mechanical device, extended use takes a toll on the different parts that make up the GK1, and, eventually, it might start showing some symptoms that a good service is in order. Anything from worn-out O-rings, weakened springs, or more complex issues such as regulator creeping or leaks, we offer a service that would do away with any of these issues. And there is also place for a little extra, in case you're interested in a deeper dive into the airguns service and updates.

Huben Airguns Shop will inspect the GK1 upon arrival and determine whether the selected service is correct according to the year of manufacture. Should it not match our requirements, we will inform you about the price difference, and you'll be able todecide whether to proceed or not.

Airguns should be sent without any scope mounted on them, without ammunition nor any air in them. Ideally the GK1 should be sent in its original box; any other box/case might be subject to an extra cost, depending on the volume. We advise forwarning us so that we can evaluate each case.
