G'day Rugster, and et al.,
I purchased one of the new Henry Mini-bolts for my son when they first came out. It has been a very good shooter and is very well proportioned for youths. Very accurate! The fiber optic sights are a big plus!
Trigger group was a bit rough out of the box. Only modification was to apply a minimal amount of grease to the bearing surfaces to get them to move freely.
Note: this is only a single shot and you do have to articulate the striker for each shot. That spring is pretty stiff.
Good Luck in you search. Merry New Year! Cheers!
