Flobert in 22 long (not long rifle), so it's fairly rare because most were .25. Circa 1870-80. Locking breech rifle (not a rolling block). Also known as a "gallery gun", popular for small game in the time. French made.
My first AR I built. Aero upper and lower. Faxon barrel. BCM KMR hand guard. POF trigger, Maxim Defense brace. Romeo 5, radical firearms suppressor. More to come =)
