My experience with flinters is long but paper thin. It wasn't until I got to shoot Rebel's Jackie Brown Carolina smoothbore with a Siler lock that I experienced sure and instant ignition, and I was astounded. Now I am trying to decide on a kit or an in-the-white flint smoothie. My heart is set on a French fusil or early English style with a pied-de-vache butt. However, the Siler is not correct for these guns, and most of the AFFORDABLE kits I see use the L&R locks. I could be wrong, but I have heard a lot of folks say the L&Rs have quality control and authenticity issues. Perhaps that is hearsay. I juts know that if I go the kit route, it will need to come with a fully inletted stock, as I have at least three thumbs on both hands. Anyone have thoughts on locks, speed, quality and kit guns?
