rifle musket

Greetings from Virginia, I’m new to joining the forum, been reading it for a while. Lots of good information. I have several black powder pistols, want to get into rifles.

Attempting to de-sporter a French 1859 musket I got for fairly cheap. Missing sights and bayonet lug. Figured I could use enfield sights since they look similar, not really any thing else new I could use. For the bayonet lug I couldn't find anything and was thinking I could have a new one made...
