Many amateur gun enthusiast believe only front action locks were used during the Flint lock period.
This rifle was made in Jefferson Co. Ky. possible 1820?
There's no missing/repaired wood for it to have had the huge lockplate a back action flinter had. The one in your pic is actually a double barrel that turns and has two piece lockplates with two frizzens, one for each barrel. You can see the frizzen for the bottom barrel showing in the pic.
