I recently bought a new North American Arms mini-revolver with the second cylinder, this way I can fire the .22 magnum and the .22 LR. This gun is a smooth bore, it has no rifling. It shot ok for its type at the range, did better with the magnum in the accuracy department.
They make a target model with adjustable sights, do all of their revolvers have smooth bores?
I have a Casuls Freedom Arms model from the early 80's that is a mini-revolver and it has a rifled bore.
Thanks
