welcome from southeast Vermont! There are a bunch of different level of "making your own - all the way from felling a likely looking tree for the stock to something which requires a few screwdrivers to assemble, and some secret goop to finish. most of us probably fall in the middle, as do I. If you get a "kit" from Track of the Wolf or Pecatonica, remember that these aren't "kits" like the model airplanes we built as kids - more on the order of "parts collection. If you want something more finished, look at Kibler (here's a link)

these are fantastic looking rifles, they have great parts, and i'm saving my soda can money to buy on of his Southern Mountain rifles.
in any event, you've come to the right place for a boatload of information and support. make some wood shavings on the floor, then
Make Good Smoke
