Southern Gunner just did a review/overview which shows its features and performance after a little tweaking of the hammer spring.
They told me about a year ago the Supernova would be released early this year (2017). I got tired of waiting for one and got the nova. I'm hoping when/if they release the Supernova that the thumbhole stocks will fit the Nova."Cokemaster"According to Hatsan USA, the Supernova will also available in USA next year. They will also sell a regulated version of this rifle.
