Man, that's nice. It would be so cool to hunt bushytails with that thing.
I'm just getting started with this stuff, but I love hunting squirrels with selfbows, more than deer hunting I think, so a squirrel rifle is certainly on my short list.
And it's cool that there's some original parts in it. That's good mojo for the hunt.
Make sure you share some nice harvest pictures when you venture out with it.
