Nice!
All my Hatsan's have been great shooters.
You should visit Gatewaytoairguns.org if you haven't already.
My newest addition.
Evanix RainStorm II .30 cal Mini-carbine
That's a DonnyFL silencer with the .30 tag on it.
Both the .50 and .30 were bought used from a friend in Hawaii.
Both have taken wild Boar on the Islands!
