Safety instructions (even more important)!:
The possession and purchase of our spare part is permitted, the installation is prohibited in Germany due to the increase in performance and leads to the loss of warranty claims for your marker.
This is not an original Umarex part.
I would also like to point out the risk of injury that could result from using this power pin.
When using your marker in Germany, make sure that you do not exceed the legally permitted 7.5 joules. Liability of any kind is excluded. Use in Germany is not recommended! Sale only from 18 years!
We have many other interesting tuning parts and ammunition for your marker!
