Definitely a military action. Receiver and trigger guard profile indicate late 1896 to 1901 production dates. The rolling block rifle with straight bar extractor was manufactured from 1866 to 1870 with a couple of select contracts to 1874 then not used again until the advent of the first smokeless actions in the fall of 1896. They were discontinued in favor of a new type rotary extractor/ejector in 1902.
