The M1817 common rifle (also known as Deringer M1817 rifle) was a flintlock muzzle-loaded weapon issued due to the Dept. of Ordnance’s order of 1814 produced by Henry Deringer and used from the 1820s to 1840s at the American frontier. Unlike the half-octagon barreled Model 1814 common rifle that preceded it it had a barrel that was round for most of its length. The 36-inch barrel was rifled for .54 caliber bullets. For rifling it had seven grooves.
