Yup, peeps work period. Now how hysterical, I mean historically correct on flintlock rifle guns they are well, have at it. Kudos to Daryl for showing the illustration of the full buckhorn sight. Never has a piece of shooting gear been so misunderstood and so disparaged as the old and humble buckhorn. I blame armchair gun writers for the past 50 years. They make excellent expedient peeps; deadly on running game with an experienced trigger puller backstopping the butt plate.
Others’ mileage, and sights, may vary.
