My shooting buddy has one, with a .17HMR barrel and a 20 gauge shotgun barrel, in a neat little nylon case. He likes it, though the .17HMR barrel has a rear sight that looks to be only adjustable for windage by tapping right & left.
It is drilled and tapped for a scope mount though.
Which I feel is absolutely necessary to get full performance from the wee .17!
Especially with his "fifty yard eyes".....
I think the Rossi is a better looking gun than the NEF/H&R design.
