Exceptional and Incredibly Scarce Colt Model 1855 Half Stock Sporting Rifle in rare .56 Caliber. Referenced by noted firearms historian R. L. Wilson, this rifle is one of only eighty produced in .56 Military caliber. Select walnut straight grip stock and butt plate which is numbered to stock #102. High condition example, befitting of the most advanced private or institutional collections. Certainly one of Colts finest condition revolving rifle extant we have observed, sporting or military.
