I am considering building an 1842 Smootbore from parts.

One approach would be to start with a Dunlap stock and add original parts and utilize a custom barrel from Whitacre or Hoyt.

Another would be to start with an Armisport 1842 and customize it.

How interchangeable are Armisport parts with original parts?

The nice thing about going the Armisport route is the firearm is functional from the start.

Thanks,
Steve
