The kit i built is Deer Creek Mountain Rifle in .45cal The rifle was somewhat scary when i first opened the box and took notice to the carving and sanding that was in store but at the end, I finished the rifle in 4 days. Traditions and Lyman are pretty much the only 2 makers that offer affordable rifles to the average man. I own a Traditions kentucky classic flintlock " pictured below" that i bought and refinished, Beautiful shooting rifle and very easy to handle in the woods. The deer creek mountain rifle is a hell of a shooter. I personally would go with a rifle kit, you can do so much more with it and do it the way you want it. Shaping, finish, what ever way you want, a kit is the way to go if you want a rifle built to your personal liking.
Heres the deer creek below.
Heres a good place to look at kits they offer and see what you like. cayugad bought the traditions hawken and has had good success with it so far.

Also, the cva mountain rifle is exactly like mine, except my rifle has a Douglas barrel and is a .45, Great price on the rifle.
