All guns or materials should be checked by a qualified gunsmith before using.
I built this matchlock rifle a few years ago, it has a green mountain 54 cal. barrel, made everything else of my own design including auto opening pan cover.
Also a link to a hunting story using it to bag a white tail.

And a 50 cal matchlock pistol with a bayonet made from scratch.
