Jjim Kibler's offerings are on the money for build, performance and value. Built a .54 Colonial about 4 years ago, just completed a .45 SMR, have another .54 Colonial up on the workbench. His new Woodsrunner kit looks like another winner, too. These kits will require some tooling and some smarts, not for everyone, but world's better than those offshore "screwdriver" kits and their annoying patent breech plugs. If you can well handle files, rasps, chisels, scrapers, etc, do try a Kibler kit, you won't be disappointed.
