What it is

A flintlock rifle with a screw plug under the barrel that, with a single turn, opened the breech and let the shooter load from behind and fire four to six rounds a minute. It was one of the first breech-loaders in British army service, though in a single experimental unit.

The Frenchman Isaac de la Chaumette had patented a similar screw system in 1721; Ferguson improved it and brought it into service. Only about a hundred were made because of their cost.
