Remarkable effort, if entirely dishonest. The flintlock was introduced in 1610, 167 years (nearly 200 years, as I said) prior to the Revolutionary war.

The Ferguson rifle was never adopted in large numbers because it was fundamentally unreliable, as this article illustrates-

It would likely jam before 10 rounds were ever fired, black powder being what it is. The ability to machine parts to the close tolerances required was extremely limited, as well. Only 200 were ever produced & only 2 exist today. It was not until the introduction of brass cartridges circa 1845 that breech loaders became practical at all.
Neither percussion ignition (unknown during the revolutionary war) nor rifled barrels were US military issue until the 1840's-

Early flintlock Pepperboxes were merely multibarreled smoothbore pistols with the barrel rotated by hand & the pan reprimed for every shot. Early revolvers (introduced circa 1600, 176 years prior to 1776) were mere curiosities given the limitations of black powder & flint. The notion that they were reliable is absurd. They were rare & awkward toys of the aristocracy, mostly for show, until 1819 when Elisha Collier introduced the first half assed reliable flintlock revolver, well after the revolutionary war.-

I'm pretty sure that the founders couldn't see any of that in their crystal balls, let alone the development of brass cartridges in the 1840's & smokeless powder in 1884 that spawned a whole new revolution in firearms pioneered by Browning & others.
