Originally a Civil War muzzleloading U.S. rifle-musket that was subsequently converted in the second half of the 1860s to a breech loader with a Remington Rolling Block action for use with centerfire cartridges. At the conclusion of the Civil War, the U.S. Government found itself with a surplus of hundreds of thousands of muzzle loading rifle-muskets that were quickly becoming obsolete due to the introduction of breech loading cartridge arms. The most cost-effective solution to keep up with the rapidly advancing arms technology was to convert these muzzle loading rifle-muskets to breech loaders. Many of these rifle-muskets found their way to the Western Frontier, first in the hands of the military and later remained in use by anyone that could get their hands on them. The standard two-line E. Remington & Sons address and patent dates ending in 1866 are visible on the upper tang. The barrel retains the block blade front and Model 1864 rear sight. "US" marked buttplate. "38112" marked on the left of both tangs.

Very good, with smooth gray and brown patina and some scattered mild freckling, typical of a frontier-used firearm. Wood is also very good as arsenal refinished, with scattered scratches, dents, undersized at the edges, some hairline cracks at some of the edges, and a few repaired spliced sections visible on the right of the forend. Mechanically fine.
