If you're interested in a flintlock that comes standard with many modern features, check out the new Traditions PA Pellet rifle. It's super reliable with a removable breech plug, Williams adjustable Tru-Glo metal sights, single or double trigger models, wood or soft touch stocks, a 26 inch barrel and a newly designed specially hardened frizzen.
It's light weight enough to add a scope yet still be managable to handle.
