+1, I want to get the tools so that I can do the barrel swap.
Wheeler action wrench and barrel nut wrench. Less than $100.00 and you can be a barrel swapping fool Add a go gauge, a little cellophane tape(use a couple of strips on the base of the go gauge to check that the action will not close) and you can set headspace without fear! You could also add a no-go gauge, but really not needed. If you want to use a fired casing you can also use that for headspacing as no two headspace gauges are ever the same anyway, in my experience. Really not that hard to do and rewarding to do your own work too.
