Gunz,
Either CVA or Thompson Center Arms are good for a first kit. I lean towards Thompson as I built one of their rifles several years ago. The kit was complete with well made instructions and the rifle was very accurate.
You have to decide what caliber and style of projectile. I like .50 and a faster twist so I can use both round ball and conical bullets. The round ball gives fun plinking and the conicals are for hunting. Some rifles will do well with sabot's using jacketed pistol bullets for expansion while hunting.
Thompson has a "less historically accurate" Hawkin rifle with adjustable sights. That's what I got in .45 for the first rifle and took deer with it using soft lead conical slugs.
Get a kit and have a ball with it. It is just as easy to brown the hardware as it is to blue it. Just take your time and remember to "degrease" the steel wool when polishing during the process.
Good luck!
