I saw from Kalibrgun facebook page that Airgun World is their official parts store so I decided to order a few parts from them, including hard to source part such as Kalibrgun factory regulator tester. They ship from czech republic and shipping is 40 bucks flat rate to the USA. Communication can be delayed since they are at the other side of the world but they have so far answered all my questions before purchase. I purchased twice from them and takes about 2 weeks to get to USA. Overall, good experience and would purchase again for my kalibrgun parts needs.
