Two fellows that I shoot with regularly each bought the SMR Kibler kit. One of these guys is a relatively experienced builder. He took his time with it and knew what he was doing when it came to finishes on the wood and barrel. He added a couple of custom features to his and wound up with a gorgeous rifle that shoots like a laser, but doesn't fit him very well, so he sold it to someone just getting into muzzleloader shooting.
The other guy had never built anything. Didn't know much, if anything about metal or wood finishing. He was able to put the kit together, albeit with a couple of "oops" along the way and ALSO end up with a rifle that shoots like a laser, but instead of looking like a "Showpiece", his looks more like an authentic, well used Mountain rifle that someone found in Great-grandpa's attic and he's enjoying the heck out of it.
