Is that so?
In that case, we can't discuss the sharpshooters on both sides during your recent civil war that used scopes on their muzzleloading rifles. Optical sights have been around for muzzleloading applications since at least the 1830s.
The first documented telescopic rifle sight was invented between 1835 and 1840. In a book titled
The Improved American Rifle, written in 1844, civil engineer
John R. Chapman documented the first telescopic sights made by Morgan James of
Utica, New York. Chapman gave James the concepts and some of the design, whereupon they produced the
Chapman-James sight. In 1855,
William Malcolm of
Syracuse, New York began producing his own sight. Malcolm used an original design incorporating achromatic lenses like those used in telescopes, and improved the windage and elevation adjustments. They were between three and twenty magnification (possibly more). Malcolm's and those made by L. M. Amidon of Vermont were the standard during the Civil War. Still other telescopic rifle sights of the same period were the
Davidson and the
Parker Hale.

An early practical
refractor telescope based telescopic sight was built in 1880 by August Fiedler (
Stronsdorf, Austria), forestry commissioner of Prince Reuss. Later telescopic sights with extra long
eye relief became available for handgun and scout rifle use
