I did a lot of research before I bought mine. (I would have bought a Henry lever action anyway, but not necessarily for hunting.) I have read and watched a number of reviews going as far back as 5 years. All reviews were excellent, including accuracy at longer ranges (technically "mid-range" to long range enthusiasts). The one exception in all the reviews was the heavy trigger pull. I have seen it measured between 5.5lbs all the way up to a high of 7.25lbs. Everyone has the same comment - perfect rifle, if only they would do something about the trigger.
I am really surprised that there is not a more active after-market for Henry rifles. They have been around a long time and have a pretty loyal following. But there seems to be nothing serious out there in the way of after-market parts or modifications. I assumed such an established brand would have the same sort of availability as the AR platform. I worked with my son building his AR from the ground up, and the options for everything were almost limitless.
Almost resigned myself to one of the two picatinny rails and scope (only place I seem to have any real options). Take it to a range and zero it in. Go hunt. Rinse and repeat once in a while. Not really a hobby gun that I planned to constantly tinkering with.
