With its browned barrel, case-hardened lock, brass furniture and distinctive over-size patch box, the "Mississippi Rifle" is considered by collectors to be the best looking of all U.S. military percussion longarms. During it's period of use the Model 1841 Rifle was considered to be the best weapon of its type.
